teng-arduino

Measure analog signal using an Arduino and Bluetooth communication. This program was written (and tested) for the Arduino RP2040 Connect.

https://github.com/MatthiasQuintern/m-teng has a backend that can connect to the Arduino.

Configuration

See settings.hpp for which pin needs to be connected. The program uses 3 leds for displaying device status, however these are optional.

Installation

git clone https://github.com/MatthiasQuintern/teng-arduino
arduino-cli compile --profile nanorp
arduino-cli upload --profile nanorp

Communication via Bluetooth

The Arduino will advertise a Bluetooth Low Energy service which can be used to interact with the device.

Service UUID: 00010000-9a74-4b30-9361-4a16ec09930f

  1. status (uint8_t, rn): 00010001-9a74-4b30-9361-4a16ec09930f
    • 0: ERROR: error occured: invalid command received, can not advertise Bluetooth service, etc.
    • 1: BUSY
    • 2: WAIT_CONNECT: waiting for Bluetooth connection
    • 3: CONNECTED: connected, waiting for command
    • 4: MEASURING: connected, measurement running
  2. command (uint8_t, rw): 00010002-9a74-4b30-9361-4a16ec09930f send a command to the arduino:
    • 0 - STOP: stop active measurements
    • 1 - MEASURE_COUNT: measure count measurements with interval see count and interva below
    • 2 - MEASURE: measure with interval until interrupted see count below
  3. reading (uint16_t rn): 00010003-9a74-4b30-9361-4a16ec09930f the reading from the Arduinos analog pin
  4. count: (uint16_t, rw): 00010004-9a74-4b30-9361-4a16ec09930f set the number of measurements to take with MEASURE_COUNT
  5. inteval: (uint16_t, rw): 00010005-9a74-4b30-9361-4a16ec09930f set the interval between measurements in ms
