Originally based on the radio transmitter example, from nRF5 SDK 12.1

This project is an attempt at controlling Milights using a easy to get nRF51 dongle.

• Building
  • nRF5 SDK 12.1 - Version might not be required
  • arm-none-eabi toolchain - I'm using 5.4.1
• Testing
  • CMake - Cmake is used for building the unit tests
  • Check - C Unit testing framework

1. Go to the location of your nRF5 SDK and create a projects subfolder

   git clone https://github.com/NZSmartie/MilightGateway
   cd MilightGateway/src/nrf51822_xxaa
   make

   1.1. If you want to use your own bootloader, modify ORIGIN and LENGTH to suit in src/nrf51822_xxaa/gcc_nrf51.ld

   # ...
   FLASH (rx) : ORIGIN = 0x0, LENGTH = 0x40000
   # ...

2. Using Nordic's nRF Studio, download the application firmware using your prefered method.

   Do Not Use a SoftDevice as this code requreis direct access to the radio.

Navigate to the root directory of this repository and:

mkdir build && cd build
cmake ..
make && ctest -V

There are 3 tests so far, TestCRC, TestMillight and TestUtil.

Only tests the 16bit CRC poly functions (which is requried for milight)

Tests the packet structure, integrity and auto increment of the packet counter.

Since there's a 4bit "trailer" transmitted by PL1167 radios, It is nessesscery to shift all the nibbles over 1 following that trailer in order to preserve the LSB data transmitted over the air.

1. Try to building using CMake, make life easier, ya'know.
