The BLE Blinky Example uses the LED Button Service Server module. This module implements a custom LED Button Service with an LED and Button Characteristics that are used to toggle LEDs and receive button statuses from Pitaya Go.
Before you start building, remember to set up the nRF5 SDK development environment first. See Setup the nRF5 SDK for details.
Building the example¶
You can find the source code and the project file of the example in the following folder: pitaya-go/examples/ble/ble_app_blinky.

Programming the firmware¶
If compiled successfully, the firmware is located in
ble_app_blinky/armgcc/_build with the name
While pushing the USER button, press the RESET button to enter the DFU mode. Then program the firmware using the nRF Connect for Desktop tool.
If the SoftDevice is not programmed before, remember to add the SoftDevice. The SoftDevice is located in
See Programming section for details about how to program your Pitaya Go.
You can test the example with the nRF Connect mobile app by performing the following steps:
