Firmware for a bluetooth beacon, like this https://forum.mysensors.org/topic/6951/nrf5-multi-sensor-board-12-14

This firmware acts as a eddystone bluetooth beacon, announcing RuuviTag URLs (see https://tag.ruuvi.com/). RuuviTag has different sensors and a more capable processor, so the source (https://github.com/ruuvi/ruuvitag_fw) does not fit for this beacon.

I don't know the origin of this beacon, but the "ITC PolyU HK" refers to a Hong Kong university. This beacon could be some kind of research project.

Beacon harware:

• nRF51822QFAA (Cortex-M0, 16kB RAM, 256kb Flash, SPI, I2C, UART...)
• Two buttons
• RGB LED
• MPU6050 accelerometer
• AP3216C distance and ambient light sensor
• BMP180 pressure and temperature sensor

Compiling requires:

• Linux
• nRF5 SDK v11 https://developer.nordicsemi.com/nRF5_SDK/
• ARM GCC, for example gcc-arm-none-eabi-5_2-2015q4
• Segger JLINK or compatible
