Bluetooth LE technology was designed to enable products that require lower power consumption, lower complexity and lower cost compared to the Bluetooth classic or Bluetooth high-speed systems. A typical BLE system consists of an LE controller and a host. The LE controller consists of a physical layer (PHY) including the radio, a link layer (LL) and a standard host controller interface (HCI). The host consists of a HCI and other higher protocol layers, e.g. L2CAP, SM, ATT/GATT, GAP etc. In many designs the LE controller and the host reside in two separate silicon chips and are controlled by 2 different microcontrollers. Communication between the two is transmitted via a hardware connection, e.g. UART, SPI, USB, etc. The host can send HCI commands to control the LE controller. The HCI interface and the HCI commands are standardized by the Bluetooth core specification. Please refer to the official document for more information. The HCI interface provides a significant benefit. Any Bluetooth tester can easily connect to the controller via the hardware connection, e.g. SPI, to test the controller by sending HCI commands. This removes the need to involve the host if the only interest is to test the controller. Figure 1. Bluetooth LE system with separate host and controller Sometimes the LE controller and the host can be combined into a single chipset solution. This lowers the cost of hardware, first because it reduces the number of silicon chips to one rather than two, and second because the hardware connection between the host and the controller is no longer required. Under this scenario, the host may directly control the LL/PHY. In this way, there is no need to generate the standard HCI commands, transmit the commands to the LL, and then process them. As a result, the execution time is improved and the calculation load on the CPU is reduced. However, if the HCI is removed completely, it will be more difficult to test only the controller with an external Bluetooth tester. 14/137 DocID026257 Rev 4 UM1755 Overview Figure 2. Bluetooth LE system with combined host and controller 1.1 BlueNRG ACI architecture The BlueNRG is implemented using a combined host and controller solution. An application command interface (ACI) is provided for accessing the BlueNRG host and controller. User applications, i.e. programs running in another silicon chip, can send ACI commands to control the BlueNRG. The ACI commands should be sent over an SPI connection. The SPI protocol is described in a later section. The ACI interface also supports HCI commands. If a command is received the ACI will check whether the command is for the host or for the controller. If the command is a HCI command, i.e. a command for the controller, the ACI will forward directly the command to the controller, bypassing it from the host. This implementation has two advantages: (1) normally the host can control the LL/PHY without using the HCI commands, which improves performance, and (2) user applications can still test the controller individually or set up some low-level hardware parameters with the HCI commands, without going through the host. Figure 3. BlueNRG ACI architecture DocID026257 Rev 4 15/137 137 ACI command data format 2 UM1755 ACI command data format When sending an ACI command to the BlueNRG, the command must be formatted as described in this chapter. 2.1 Overview The BlueNRG ACI commands utilize and extend the standard HCI data format. The standard HCI data format is a part of the Bluetooth core specification. To avoid redundancy and inconsistency, the texts are not copied into this document. Please refer to the official Bluetooth specification, Volume 2, Part E, Chapter 5 for detailed information. According to the Bluetooth specification, a standard HCI packet can be an: 1. HCI command packet 2. HCI ACL data packet 3. HCI synchronous data packet 4. HCI event packet In the BlueNRG, the HCI synchronous data packet is not supported, but the other three are. 2.2 HCI command packet When an external device gives a command to the BlueNRG, the command must be formatted in a HCI command packet. The BlueNRG only receives the HCI command packets, but does not transmit. Figure 4. HCI command packet *$066* Each HCI command uses a 2 byte OpCode to uniquely identify different types of commands. The OpCode is divided into two fields: the OpCode Group Field (OGF) and the OpCode Command Field (OCF). The OGF is the upper 6 bits and the remaining lower 10 bits are used by the OCF. All HCI commands are grouped into logical groups by the Bluetooth specification and each group is assigned a unique OGF value. 16/137 DocID026257 Rev 4 UM1755 ACI command data format Table 1. OGF value Group name OGF value Link Control Commands 0x01 Link Policy Commands 0x02 Controller and Baseband Commands 0x03 Information Parameters 0x04 Status Parameters 0x05 Testing Commands 0x06 LE Controller Commands 0x08 Vendor Specific Commands 0x3F Depending on the OGF, the commands can be categorized into 3 sets: 1. Standard HCI commands: the commands with an OGF value other than 0x3F. These commands are designed for the controller. All standard HCI command are clearly defined in the Bluetooth specification, so they are not described in this document. 2. Vendor specific (VS) HCI commands: the commands with an OGF value 0x3F and are designed for the controller. Each vendor can define their own VS commands based on the hardware implementation. The VS commands defined for the BlueNRG are described in this document. 3. Vendor specific (VS) ACI commands: the commands also with an OGF value 0x3F, but these commands are designed to control/access the host. The Bluetooth specification does not define any command for the host, so all the ACI commands are naturally vendor specific. The ACI commands for the BlueNRG are described in this document. To clarify, the commands designed to control the controller are called HCI commands. This name is defined by the Bluetooth specification and we maintain it here in order to comply with the specification. The commands designed to control the host are called ACI commands. We give it a different name to indicate that this command is rather assigned to the host, i.e. to the whole BLE system, and not only to the controller at the lower level. However, because both ACI and HCI commands are the commands received from the external device via the ACI interface, and both of them share the same data format, sometimes it is not very important to differentiate between the two. So in this document, when referring in general to commands, we use the term “ACI commands”. In practice, the value of the OpCode is more important. Each command, regardless of whether it is an HCI or an ACI command, matches only one OpCode value. The user application should guarantee the OpCode value is used correctly. Please note that the Bluetooth specification uses bit-wise little endian format for the OpCode. So in Figure 4, the OGF field is placed to the right. But in this document, when writing an OpCode in the format of 0xXXXX, we imply the most significant bit to the left. For example, if an OpCode is 0xFE81, its top 6-bit OGF is “111111”, i.e. 0x3F, so it is a vendor specific command. And its OCF is 10-bit 0x281. For another example, if an OpCode is 0x0406, the 6-bit OGF is 0x01, and its OCF is 0x06. So this is a standard HCI command, HCI_Disconnect. DocID026257 Rev 4 17/137 137 ACI command data format 2.3 UM1755 HCI event packet The BlueNRG uses event packets to acknowledge a command or to notify that its status has updated to the user application. The BlueNRG only sends HCI event packets, but does not receive them. Figure 5. HCI event packet *$066* 2.4 HCI ACL data packet The ACL data packets are used to exchange data. Figure 6.

The sequence is in case of starting advertising. When using the commands at HCI level, the correct sequence has to be followed as below: 1. HCI_LE_Set_Advertising_Parameters - Used to set the advertising parameters. 2. HCI_LE_Set_Advertising_Data - Used to set the data used in advertising packets that have a data field. 3. HCI_LE_Set_Scan_Resp_Data- Used to set the data used in scanning packets that have a data field. 4. HCI_LE_Set_Advertise_Enable - Turn on Advertising. DocID026257 Rev 4 21/137 137 Vendor specific commands 4 UM1755 Vendor specific commands The VS commands can be either ACI VS commands to access the host of the BlueNRG, or the HCI VS commands to access the LE controller. Both types of the commands use the OGF value of 0x3F. 4.1 VS command and VS event format The OCF field of the OpCode of the VS commands is further divided into two fields: Command Group ID and Command ID. Figure 7. OpCode format for VS Commands 2*) 2&) &RPPDQG,'&,' &RPPDQG*URXS,' &*,' ELWV ELWV %LWV *$066* Figure 7 above gives the 16-bit OpCode format (see also Section 2.2). The OGF field is always 0x3F for VS commands. The 10-bit OCF field is split into two parts: 3-bit Command Group ID (CGID) and 7-bit Command ID (CID). The CGID is used by the BlueNRG ACI interface to route the commands to different logical layers, e.g. L2CAP, GAP, GATT, etc. It also helps to categorize the VS commands with a more clear structure. The CID determines the ID of each command. Each CGID group can have up to 128 VS commands. Table 4. CGID group Command group Description CGID HCI HCI extension commands 0x0 GAP Generic access profile commands 0x1 GATT Generic attribute profile commands 0x2 L2CAP L2CAP commands 0x3 Reserved 0x4 – 0x7 The VS event also has a slightly different format than the standard HCI event (see also Section 2.3). (1) The 8-bit event code of the VS event always has the value of 0xFF. (2) The 16-bit event parameter 0 has a different format. 22/137 DocID026257 Rev 4 UM1755 Vendor specific commands Figure 8.

These 2 bytes together are defined as the BlueNRG Event Code (ECODE). ECODE is further divided into 2 fields: Event Group ID (EGIO) and Event ID (EID). BlueNRG combines the events into logical groups using the EGID. And the EID is used to specify an event in the group. The EGID occupies 6-bits in the ECODE field while the EID occupies the remaining 10 bits. Table 5.

Broadcaster shall have a transmitter and can optionally have a receiver. • Observer: In observer role device receives the advertising events. An observer shall have a receiver and can optionally have a transmitter. • Peripheral: Any device that accepts the establishment of LE physical link is referred as peripheral. A device operating in peripheral role will be slave in LL connection state. A peripheral shall have both a transmitter and receiver. • Central: A device that initiates the establishment of LE physical link is referred as central device. A device operating in central role will be master in LL connection state. A central shall have both a transmitter and receiver. BlueNRG is capable of being the peripheral or central in the GAP profile context because: • BlueNRG controller is capable of acting as a slave in a connection, i.e. it can accept the LL connection request from a central device and can support all the mandatory requirements of the GAP peripheral role as dictated in Table 2.1, Part C, Generic Access Profile of Bluetooth core specification 4.0. • BlueNRG controller is capable of acting as a master in a connection, i.e. it can issue the LL connect request to a peripheral device and can support all the mandatory requirements of the GAP central role as dictated in Table 2.1, Part C, Generic Access Profile of Bluetooth core specification 4.0. 28/137 DocID026257 Rev 4 UM1755 4.3.2 Vendor specific commands GAP VS Commands Table 17.

This event will be given to the application only if the event bit for this event generation is set when the characteristic was added. When this event is received, the application has to check whether the value being requested for write can be allowed to be written and respond with the command Aci_Gatt_Write_Response. The details of the parameters of the command can be found. Based on the response from the application, the attribute value will be modified by the stack. If the write is rejected by the application, then the value of the attribute will not be modified. In case of a write REQ, an error response will be sent to the client, with the error code as specified by the application.

Aci_Hal_Set_Tx_Power_Level Command name Parameters EN_HIGH_POWER PA_LEVEL Aci_Hal_Set_Tx_Power_Level(0xFC0F) Return Status Description: This command sets the TX power level of the BlueNRG. By controlling the EN_HIGH_POWER and the PA_LEVEL, the combination of the 2 determines the output power level (dBm). See the table below. When the system starts up or reboots, the default TX power level will be used, which is the maximum value of 8 dBm. Once this command is given, the output power will be changed instantly, regardless if there is Bluetooth communication going on or not. For example, for debugging purpose, the BlueNRG can be set to advertise all the time. And use this command to observe the signal strength changing. The system will keep the last received TX power level from the command, i.e. the 2nd command overwrites the previous TX power level. The new TX power level remains until another Set TX Power command, or the system reboots. Table 285.

Aci_Hal_Device_Standby Command name Parameters Aci_Hal_Device_Standby (0xFC13) Return Status Description: Normally the BlueNRG will automatically enter sleep mode to save power. This Aci_Hal_Device_Standby command further put the device into the Standby mode instead of the sleep mode. The difference is that, in sleep mode, the device can still wake up itself with the internal timer. But in standby mode, this timer is also disabled. So the only possibility to wake up the device is by the external signals, e.g. a HCI command sent via SPI bus. Based on the measurement, the current consumption under sleep mode is ~2 uA. And this value is ~1.5 uA in standby mode. The command is only accepted when there is no other Bluetooth activity. Otherwise an error code “command disallowed” will return. Table 289.

This command implements this feature. If the Direct TX test is started, a 32-bit counter will be used to count how many packets have been transmitted. After the Direct Test End, this command can be used to check how many packets were sent during the Direct TX test. The counter starts from 0 and counts upwards. As would be the case if 32-bits are all used, the counter wraps back and starts from 0 again. The counter is not cleared until the next Direct TX test starts. Table 291.

The external device normally is an application processor. It sends ACI commands to control the BlueNRG device. And the BlueNRG generates ACI events to report back to the external application processor. The ACI commands and events are transmitted through the SPI bus. This chapter describes the BlueNRG hardware SPI interface. Also it describes the communication protocol over the SPI bus between the BlueNRG and the external device. 5.1 Hardware SPI interface The BlueNRG SPI interface is Motorola protocol compliant, which has 5 wires: CLK (clock), nCS (chip select), MOSI (master output slave input), MISO (master input slave output), and DataRdy_IRQ (transmit interrupt request). The BlueNRG always behaves as the slave device on the SPI bus. The external device must be the SPI master. The table below shows the 5 SPI pins on the BlueNRG device, including the pin number of the silicon chip and the pin direction from the BlueNRG's side. Table 298. SPI pins Pin name Pin n° Direction SPI_CLK 2 Input SPI_NCS 31 Input SPI_MOSI 1 Input SPI_MISO 32 Output SPI_IRQ 3 Output Here is the summary of the SPI parameters: 1. The CS line is active low. 2. The clock signal can go up to 8 MHz, or can go as low as 100 kHz. 3. The clock is inactive low, i.e. the clock polarity CPOL = 0. 4. The data is valid on clock leading edge, i.e. the clock phase CPHA = 0. 5. The data transfer is always 8-bit byte based. 6. For each byte, the Most Significant Bit is sent first. Figure 9 shows how to connect BlueNRG SPI bus to an external SPI master. DocID026257 Rev 4 131/137 137 SPI interface UM1755 Figure 9. SPI wire connection The SPI master, i.e. an application processor, always controls when to start an SPI transaction. This can happen at any time. It is started by putting low the nCS line to activate the BlueNRG device. Then the master should provide the SPI clock. Together with the clock, the master should output the data on the SPI bus through the MOSI line, either dummy data or valid data. At the same time, the slave returns data from the MISO line, because SPI is in principle a shift register. When the SPI master wants to send data to the BlueNRG, i.e. an SPI write, it sets nCS to low, then sends the SPI clock and dummy data to read an SPI header from the BlueNRG. The SPI header format will be described in the following section. If the SPI header indicates that the BlueNRG has enough space in the buffer, the SPI master can then send real data over the SPI bus. The SPI master should not overwrite the BlueNRG SPI buffer, otherwise the communication will fail. When the BlueNRG wants to send data to the SPI master, i.e. an SPI read, it must use the IRQ pin, because the SPI slave cannot control the nCS line. The BlueNRG will set the IRQ pin to high, which notifies the SPI master that there is data to be read. Then the SPI master should start an SPI transaction, reading the SPI header, and from where it will know how many bytes it should read back from the BlueNRG. The SPI master should not read bytes other than those indicated as the SPI header, otherwise the communication will fail. The DataRdy (IRQ) pin of the BlueNRG should work as follows: (1) it must be high when BlueNRG has data to send to the SPI master; (2) It must be high impedance when BlueNRG has no data to send to the SPI master. On the SPI master side, this pin must be configured as an input pin. The SPI master may poll this pin, or use it as an interrupt source, to detect when an SPI read is required. Also there should be a pull down resistor, either on the SPI master IRQ pin or externally connected. This pull down resistor makes sure the DataRdy value goes back to 0, so it does not confuse the SPI master to misread data. Note that the reason that IRQ pin must be high-Z when there is no data to send is because we also use this pin as input when BlueNRG boots up. The IRQ pin value will determine if the updater mode is required or not. After the BlueNRG goes to normal working state, the IRQ pin is configured as output for SPI interface. Note also that the MISO also goes to high-Z when BlueNRG does not send data. This allows multi-SPI slaves on the same bus. This other SPI slave may access the bus when BlueNRG does not. 132/137 DocID026257 Rev 4 UM1755 5.2 SPI interface SPI communication protocol To communicate with the BlueNRG, the data on the SPI bus must be formatted as described in this section. An SPI transaction is defined from the time instant when the master puts the nCS line to low, until the time instant when the nCS line is back to high. Each SPI transaction should contain 1 data frame. Each data frame should contain at least 5 bytes of header, and may have 0-N bytes of data. 5.2.1 Header Figure 10. SPI header format Figure 10 above shows an SPI frame, with minimum 5 bytes SPI header, and 0 byte SPI data. The header of the master is on the MOSI line, which is 1 control byte and 4 bytes 0x00. The control byte can have only the value of 0x0A (SPI write) or 0x0B (SPI read). The BlueNRG returns the slave header on the MISO line at the same time. The 1st byte is the SPI READY indication. It must be 0x02 to indicate the slave SPI interface is ready. If it is any value other than 0x02, the master must ignore the following 4 bytes and abort the SPI transaction. If the BlueNRG SPI is ready (Ready byte = 0x02), the following 4 bytes give 2 buffer sizes for write and read, 2 bytes for each buffer. Of the 2-byte buffer size, the lower byte comes first, then the higher byte. The write buffer size means how many bytes the master can write to the BlueNRG. The read buffer size means how many bytes in the BlueNRG are waiting for the master to read. For example, if the slave header is 0x0200010500, the write buffer size is 0x0100 and the read buffer size is 0x0005. So the master cannot write more than 256 bytes to the BlueNRG, and it should read back 5 bytes from the BlueNRG as soon as possible. The SPI master may poll the BlueNRG by sending dummy SPI headers, just to check what value is in the BlueNRG SPI header. For example, the SPI master can send an SPI frame with only 5 bytes header: the CTRL byte can be either write or read, then following 4 bytes 0x00 dummy bytes. After the header, the SPI master stops the frame, without sending any real data. So the write/read action will not happen in practice. DocID026257 Rev 4 133/137 137 SPI interface 5.2.2 UM1755 Write data to BlueNRG To write data to the BlueNRG, the SPI master must start an SPI frame to check the BlueNRG SPI header, and the following 3 conditions must be met: 1. The master sends the CTRL byte as 0x0A. 2. The slave replies with SPI READY byte as 0x02. 3. The write buffer size is bigger than 0. If so, the master can put the data bytes following the 5 header bytes on the MOSI line in the same transaction. If the master is fast enough, it may start sending data bytes immediately in the same SPI transaction where the 3 conditions are just seen satisfied. Or the master may choose to stop the SPI transaction for now, go back to prepare the data, and send them in a later SPI transaction. The SPI master is allowed to write less bytes than the write buffer size, but it is forbidden to write more. In case an ACI command packet is bigger than 128 bytes. The master has to send it in 2 SPI write transactions. The master firstly sends 128 bytes, then waiting for the write buffer to be available again, and then write the remaining bytes. The BlueNRG will count how many bytes are actually received on the MOSI line. So the master does not need to indicate how many bytes it intends to write. The write buffer size value is the data bytes of the payload. It does not include the 5 header bytes. When the master is sending real data bytes on the MOSI line, the BlueNRG will return the same amount of bytes from its own shift register. The master should ignore these bytes. 5.2.3 Read data from BlueNRG The BlueNRG uses the IRQ pin to notify the SPI master when it has data to be read. When the SPI master sees the IRQ pin become high, it should read data from BlueNRG. The protocol is similar to SPI write. The SPI master starts a transaction to check the SPI header. The master puts 0xB in the CTRL byte, and checks again if the slave is ready (0x02), and the read buffer size is non-zero. Then the master sends certain amount of dummy bytes (e.g. 0x00 or 0xFF) on the MOSI line, while reading back the slave data from the MISO line. The reading process can happen in 1 SPI transaction or in multiple SPI transactions. The SPI master should read from BlueNRG as long as the IRQ pin is high. 134/137 DocID026257 Rev 4 UM1755 5.2.4 SPI interface SPI operation with BlueNRG sleep mode The BlueNRG device is designed with a deep sleep mode, in which it turns off most of the internal functions to save power. The BlueNRG goes into sleep mode automatically when there is no Bluetooth activity ongoing. So it is very likely that the BlueNRG is sleeping when the master starts an SPI transaction. The BlueNRG wakes up as soon as the nCS line is put to low. But then it needs to initialize and prepare the SPI buffers. This will take some time. So the following sequence is likely to occur on the SPI bus: 1. The master puts the nCS line to low and the BlueNRG wakes up. BlueNRG is expecting a command within 2 ms before going to sleep. 2. The master sends the header, but the BlueNRG replies with the READY byte as 0x00 or 0xFF. This means the BlueNRG SPI interface is still not initialized. 3. The master keeps polling the BlueNRG, (releasing and asserting CS again). In order to read again the header, the SPI master has to release the CS line and assert it within 2ms from the previous CS assertion. After a while, the READY byte becomes 0x02 but both the buffer sizes are 0x00. This means the BlueNRG SPI is initialized, but the buffer is not yet prepared. 4. As soon as the buffer size becomes non-zero, the master can write data to the BlueNRG. With the measurement, the master should allow about 0.5 ms for the BlueNRG to be completely ready for the SPI communication. Note that 0.5 ms is when non-retention RAM of BlueNRG must be initialized upon wakeup (i.e. device in mode1 - slave only mode). The value can be 0.3 ms if non-retention RAM initialization is not required, which makes the SPI ready faster. This waiting operation is only needed when the SPI bus is idle for a while. If the master is continuously writing, from the 2nd write transaction there is no need to wait, because the BlueNRG will not sleep if there is still SPI data to be processed. Also, there is no need to wait when reading from the BlueNRG, because it cannot sleep if it still holds data for the master.
