This project is intended to help you get familiar with the Qualcomm Robotics RB3 Bluetooth application and to verify the initial setup and working of the Bluetooth functionality.

Objective

Test the basic functionalities and features of Bluetooth settings on the Qualcomm Robotics RB3 Development Kit using Bluetooth application.

Materials Required / Parts List / Tools

• Robotics DragonBoard™ 845c development board - Based on the Qualcomm® SDA845 processor
• Power Adapter - 12 V with 2500 mA required by the 96Boards specification
• USB to Micro USB cable - For serial console interface and ADB, Fast boot commands
• USB to USB Type C cable - For connecting the USB3.0 Type C port and flashing images
• Ubuntu 14.04 LTS Linux distribution for 64-bit architecture - Host PC OS for RB3 SDK build process

Source Code: BT Application

Build / Assembly Instructions

Prerequisites:

Complete the build instructions in the "Hello RB3" project, and make sure that the following steps are done before proceeding with running the application on device:

1. Setup the development environment

• 1.1) Install Android SDK tools (ADB, Fastboot)
• 1.2) Install and configure the USB driver
• 1.3) Flash the firmware image on the board
• 1.4) Setup serial port for debugging purpose
• 1.5) Install the App Toolchain SDK,/li>

 

2. Bluetooth application:

• 2.1. From the Thundercomm Qualcomm Robotics RB3 Development Kit web page, under the Technical Documents tab in the “Sample-apps-codes” section, download source code for the Bluetooth application : “bt-app_test.tar”

• 2.2. After decompressing the .tar file, the directory is as follows:

3. Build and transfer the application:

• 3.1. Check the configuration script for running makefile by using ‘cat’ command. Compile and build the application using makefile.

• 3.2. Build the application:

  Load the environment setup for arm7 using ‘source’ command

• 3.3. Transfer the application:

  Connect the Qualcomm Robotics RB3 board to the host PC via Type C cable and ensure that the ADB port can be used (check using ‘adb devices’ and connect using ‘adb shell’)

  Transfer the application on to the Qualcomm Robotics RB3 board:

• 3.4. Once the application is pushed on the Qualcomm Robotics RB3, run

in the background (only once at the beginning) before running

• 3.5. After executing the “btapp”, type “gap_menu” command and press Enter

Next, as a result of the "gap_menu" command, the below menu of options will display for activities to be done using Bluetooth, such as enable, disable, inquiry etc.

If the gap_menu command is successful in displaying the menu for Bluetooth settings, external devices can then be connected to the board to perform various Bluetooth operations.
