Parc Technologique PRE ROUX IV 283 rue Louis NEEL 38920 CROLLES - FRANCE declares that the product if used and installed according to the user guide available on our web site : www.adeunis-rf.com Product Name: ARF32 Product Number(s): ARF7044A is designed to comply with the RTTE Directive 99/5/EC: EMC: according to the harmonized standard EN 301 489. Safety: according to the standard EN 60950-1/2001 Radio: according to harmonized standard EN 300-328 covering essential radio requirements of the RTTE directive. Notes: - Conformity has been evaluated according to the procedure described in Annex III of the RTTE directive. - Receiver class (if applicable): 3. According to the 1999/519/EC recommendation, minimum distance between the product and the body could be required depending on the module integration. Warning : - CE marking applies only to End Products: Because this equipment is only a subassembly, conformity testing has been reduced (equipment has been design in accordance to standards but full testing is impossible). Manufacturer of End Products, based on such a solution, has to insure full conformity to be able to CE label marking. - As the integration of a radio module requires wireless technological knowledge, ADEUNIS RF proposes its technical proficiency to its customers for a precompliance qualification of end products. In case of no-conformity, ADEUNIS RF will not be held back responsible if this stage has not been.

The ARF32 module fully complies with the V2.0 Bluetooth® standard and data rate goes up to 723 kbps. Data exchange and set-up are only done through an UART data port, under SPP profile. A miniature antenna is integrated. ARF32 can be used in two modes: Classical Bluetooth® mode : Master starts with GAP identification, then, SDAP profile review, SPP connection and transparent communication. Ref. 08-07-V10-ltu p6 TOP A RF32 User Guide Automatic Bluetooth® mode: Identification, profile review and connection to 1 to 3 known slaves are recorded by the master. After booting, Bluetooth® link is directly open in transparent mode. ARF32 modules are available as standalone ARF7044 module or in the ARF7069 DemoKit. This DemoKit can be fully set-up and used with the National Semiconductors® “Simply Blue Commander” Software.

Data Rate Jumper (red link) In case of setup error while evaluating, communication with ARF32 module can be lost (bad UART parameters setup). By connecting the “Data Rate Jumper”, UART settings are forced to : • Data rate = 9600 bps NB : other settings (Parity, Stop bit & Flow control…) remain the same and have to be check for recovery values.. It becomes possible to re-program the “Non volatile Settings” to access again the ARF32 Module. When done, jumper can be removed.

The command mode is used to set up the Bluetooth® link between two pieces of Bluetooth® equipment. The transparent mode is used to transfer data between two pieces of Bluetooth® equipment. Command mode A specific protocol is used to send commands to the Bluetooth® module. The frame format is the following : All the values are in hexadecimal format. Start delimiter 1 byte Packet type 1 byte Operation code 1 byte Data length 2 bytes Checksum 1 byte Data <data length> bytes End delimiter 1 byte Start delimiter: 02 (<STX>) Packet type : 52 (‘R’ for request), 69 (‘i’ for indication), 43 (‘C’ for confirm) Operation code : command dependent Data length : size of data. First byte is the Least Significant Byte and second byte is the Most Significant Byte Checksum: Sum of all bytes from the packet type field to the data length field Data : command data End delimite r: 03 (<ETX>) Example of the inquiry command Start delimiter 02 Packet type 52 Operation code 00 Data length 03 00 Checksum 55 Data End delimiter 0A 00 00 03 Frame : 02 52 00 03 00 55 0A 00 00 03 Ref. 08-07-V10-ltu p 13 TOP A RF32 User Guide Transparent mode In this mode all the data received on the UART RX pin are sent by radio to the target Bluetooth® module and will be available on the target Bluetooth® module UART TX pin. Mode selection A specific command (transparent mode) is used in order to switch from command mode to transparent mode. A specific pattern : “UART break” is used to switch from transparent mode to command mode. Setting up a link using the command interface Quick start using “Simply Blue Commander” SBC software (*) : Connect one module with the RS232 link to a PC supporting SBC software. Setup “SBC Configuration / Transport layer” at the current baudrate (default 9600), 8 bits, 1 stop, no parity, “Low level driver” & “CTS output flow control” enabled. Power up the two Bluetooth® modules. SBC must return: < Rx: Event: SimplyBlue Ready, SW Version: 0212 It means Master Module, serial port setup and connection are OK Open “SBC ARF32 DATA over SPP quick start” commands sub directory. > Click “BT environment inquiry” & “Send” < All BT devices nearby send their own BDADDR & Class of Device (SPP modules class of devices = 000000) > Click “SPP link establishment”, replace FFs with slave BDADDR & “Send” In bold : address of the target Bluetooth® module, discovered during previous step. < Target module will confirm the connection (State has to be 00) > Click “Enter SPP transparent mode” & “Send” < Target module will confirm entering transparent mode (State has to be 00) You can now close SBC and use any kind of terminal software to exchange data or files through the Bluetooth SPP link.

Ref. 08-07-V10-ltu p 14 TOP A RF32 User Guide Final use with a PC terminal or a microcontroller Power up the two Bluetooth® modules. Connect one module with the RS232 link to a PC or Notebook or PDA. Use a terminal software configured at the current baudrate (9600 by default), 8 bits, 1 stop, no parity, flow control material. Please find below a typical request / response sequence in order to establish a typical link. All requests must be sending by the PC / NB / PDA (i.e. the master). All indication and confirm responses are sent by the Bluetooth® slave module: > GIAC Inquiry request: < Inquiry module indication: 02 52 00 03 00 55 0A 00 00 03 02 69 01 09 00 73 34 BE 1F 17 00 08 00 00 00 03 In bold : address of the target Bluetooth® module. This address will be used within the command SDAP Connect and the command SPP Connect < Inquiry module confirm: 02 43 00 01 00 44 00 03 > SDAP connect request: 02 52 32 06 00 8A 34 BE 1F 17 00 08 03 < SDAP connect module confirm: 02 43 32 01 00 76 00 03 > SDAP service browse SPP request: 02 52 35 02 00 89 01 11 03 < SDAP service browse SPP module confirm: 02 43 35 0D 00 85 00 01 02 10 01 11 01 05 43 4F 4D 31 00 03 > SDAP disconnect request: 02 52 33 00 00 85 03 < SDAP disconnect module confirm: 02 43 33 01 00 77 00 03 > SPP connect request: 02 52 0A 08 00 64 01 34 BE 1F 17 00 08 01 03 < SPP connect module confirm: 02 43 0A 02 00 4F 00 01 03 < SPP connect module indication: 02 69 3E 04 00 AB 01 0C 00 00 03 > Enter transparent mode: 02 52 11 01 00 64 01 03 < Enter transparent mode module confirm: 02 43 11 02 00 56 00 01 03 Now you can exchange data in transparent mode between the two Bluetooth® modules. To come back to the command mode you have to send an UART break. Ref. 08-07-V10-ltu p 15 TOP A RF32 User Guide Automatic connection For serial cable replacement the ARF32 master can be configured to connect automatically to a specific ARF32 slave and switch to transparent mode. The automatic connection is done on boot or reset. The ARF32 master tries 3 times the link establishment. In order to do this the following commands have to be entered one time on the ARF32 master with for example the “Simply Blue Commander Software: > Store default connection request : 02 52 13 0A 00 6F 01 01 01 34 BE 1F 17 00 08 01 03 < Store default connection confirm 02 43 13 01 00 57 00 03 In bold : address of the target bluetooth module. > Write operation mode (auto) request : < Write operation mode confirm 02 52 4A 01 00 9D 01 03 02 43 4A 01 00 8E 00 03 Advanced commands Other commands are available in command mode.
