Purpose / Scope

This sample project is used to add observer role to a peripheral Bluetooth low energy peripheral device to show scanning functionality in a peripheral based project. The project is based on simple_peripheral. This project is configured to run on the CC2650 Launchpad.

Method

  1. Compile and load the projects:

    • First build and load cc2650lp_stack
    • Next build and load cc2650lp_app

  2. Connect to the LaunchPad via PuTTY (or other serial console emulator). For instructions on connecting via PuTTY, please see our FAQ page.

  3. After connecting you will notice that the device is advertising, the terminal will display as below. (note that your BD_ADDR may be different)

 Advertising

  4. You may initiate scanning at any time by pressing KEY_LEFT (BTN-1), scanning may be canceled via KEY_RIGHT (BTN-2). Scan reports are displayed on the terminal as

     Scanning On
 Device info 1. 0x247189083301
 Device info 2. 0x247189083A84
 Device info 3. 0xB0B448EE1902
 Device info 4. 0x68C90B07B68B
 Device info 5. 0x9059AF0B7C82
