Sample iBeacon implementation for the nRF52 chipset.
The build environment uses CMake and assumes an nRF52 Development Kit from Nordic Semiconductor.
Press Button 1 on the DK to start advertising in a loop. LED 2 should light up.
In the default configuration, the beacon will advertise for 3 seconds (LED 3 on) followed by 17 seconds of silence.
In each advertising pulse, the beacon's minor value will increment from 1 to 20.
By default, the beacon broadcasts the following identity:
- Proximity UUID: 33013f7f-cb46-4db6-b4be-542c310a81eb
- Major: 204
- Minor: 1 .. 20
Create a CMakeEnv.cmake file on the same level as CMakeLists.txt, with the following contents:
set(ARM_NONE_EABI_TOOLCHAIN_PATH "PATH_TO_ARM_GCC_TOOLCHAIN")
set(NRF5_SDK_PATH "PATH_TO_NORDIC_NRF5_SDK")
set(NRFJPROG "PATH_TO_NRFJPROG")
Example using nRF5 SDK 14.2.0, and the most recent version of the GCC ARM toolchain:
set(ARM_NONE_EABI_TOOLCHAIN_PATH "/Users/ahs/local/gcc-arm-none-eabi-7-2017-q4-major")
set(NRF5_SDK_PATH "/Users/ahs/local/nRF5_SDK_14.2.0_17b948a")
set(NRFJPROG "/Users/ahs/local/nRF5x-Command-Line-Tools_9_7_2_OSX/nrfjprog/nrfjprog")
Generate makefiles and build out of source tree:
cmake -H. -B"build"
cmake --build build --target nrf52-ibeacon
cmake --build build --target FLASH_ERASE
cmake --build build --target FLASH_SOFTDEVICE
cmake --build build --target FLASH_nrf52-ibeacon
