Bluetooth Low Energy Data Connection to iOS Device This demonstration show how serial data is transmitted from BM77EVB (via PC Chat) to an iOS device using Bluetooth Low Energy connection. This demonstration uses ISSC BLETR APP to connection to the BM77EVB. Bluetooth Low Energy is utilized since iOS devices do not support Bluetooth Classic SPP data connections. A key feature of the BM77 is transparent serial data connection from BM77 UART to an iOS device. a. Using an iPhone 4S or later, iPad3 or later device, download and install “ISSC BLETR” APP. As illustrated below, the BLETR App is available on the AppStore. © 2014 ISSC Technologies Corp. 17 b. Turn on the Bluetooth radio in iPhone, iPod or iPad Settings application. c. Go to Settings/ General/ Bluetooth Page. d. Turn ON the Bluetooth. e. Launch the iSSC BLETR APP and it will scan the Bluetooth Low Energy Peripheral devices and list them. If the device does not appear press the “Refresh” button to restart the BTLE peripheral scan. Find the Dual-SPP BTLE peripheral device. Select it to start a connection to the BM77EVB named Dual-SPP. f. After a successful connection to BM77EVB, BLETR will display the device as connected as shown below. © 2014 ISSC Technologies Corp. 18 g. Select the connected Dual-SPP device to display the top level view. This view presents three options when connected to a BM77EVB. Transparent - View to display received data, send data, and enable features Proprietary- This view sets Bluetooth Low Energy connection parameters Device Info -This view displays the settings for Bluetooth Low Energy Device Information Service © 2014 ISSC Technologies Corp. 19 h. Selecting “Transparent” button opens the transparent Serial Data view as shown below. The default mode is Raw (ASCII) mode where any data characters received are displayed in the large text box in red font. Data Mode Transfer © 2014 ISSC Technologies Corp. 20 To send data from BLETR iOS device to the BM77, select the input text box. The soft keyboard will be displayed as shown below. Enter text in the input text box. Click “Send” button to transmit text to BM77. After clicking “Send” the text is received via the BM77 UART and displayed in the BT CHAT text window. © 2014 ISSC Technologies Corp. 21 Timer Feature In addition to Raw mode (ASCII) the Transparent data view also has Timer and Echo features. The Timer feature allows the BLETR to send a repeated test pattern to BT CHAT for test throughput and data transfer test. An example of the “Timer” test feature is shown below. BLETR configured to transmit a 100 test blocks of 20 characters, every 1000ms. BT CHAT tool receives the test pattern data and displays it in red text. The line break indicates a Bluetooth Low Energy packet break, meaning a transmittted test block was fragmented into multiple BLE packets. Clicking the “Start” button initiates the data transfer. © 2014 ISSC Technologies Corp. 22 Tx File Feature Another test feature similar to the Timer feature is the “TX File” transfer. The “TX File” functions transfers files, which as embedded in the BLETR APP, to the BM77. The steps to use this feature are as follows: a. Click the “TX File” button to open a dialog with list of file sizes to transmit b. Select the file size to send c. Observe the file received on BT Chat. c b a © 2014 ISSC Technologies Corp. 23 Echo Feature The Echo feature is an optional function for the Transparent data view. When Echo is enabled, any data received by BLETR is echoed back to sender. The example below show text sent from BTCHAT being echoed to BLETR when the Echo mode is enabled. © 2014 ISSC Technologies Corp. 24 Device Information Feature The Device Information view displays the characteristics associated with Device Information service. The Device Information service is available to all Bluetooth 4.0 low energy host that access the BM77EVB. It exposes the information identifying information about the BM77 peripheral device. These values can be programmed using a configuration tool described in the application note. © 2014 ISSC Technologies Corp. 25 Proprietary (Configuration) Feature The Proprietary view demonstrates the capability to change Bluetooth Low Energy connection parameters remotely via BLETR application. These parameters only affect Bluetooth Low Energy connections. 1. Max Interval: time (ms) between communication interval between BM77 and Bluetooth LE Central device. 2. Connection Timeout: time (ms) between communication events before a connections considered lost 3. Latency: Number of connection events peripheral (BM77) is allowed to skip 4. Bluetooth LE Name used to advertise Peripheral name to scanning Central devices. Enter new name in text box and click “Change Name” to invoke change. © 2014 ISSC Technologies Corp. 26 5.
