  1. Download the latest Arduino IDE from https://www.arduino.cc/en/Main/Software
  2. Add the SODAQ board manager URL http://downloads.sodaq.net/package_sodaq_index.json to File → Preferences → Additional Board Manager URLs and install the SODAQ board files.
  3. Select SODAQ ONE board from Tools.
  4. Install the SODAQ RN2483 library. Search for RN2483 under Sketch → Include Library → Manage Libraries...

Sodaq One configuration

The configuration is based on the code from https://github.com/SodaqMoja/SodaqOne-UniversalTracker-v2

In order to reduce the battery consumption, the GPS usage is disabled and only the temperature and the battery status are sent. The following modifications are made in the code:

Modifications in SodaqOneTracker_v2/Config.cpp

  1. Default settings in void ConfigParams::reset() 
    _defaultFixInterval = 0;//15;
    _repeatCount = 5;//0;
    _isAdrOn = 0;//1;
    _spreadingFactor = 12;//7;
    _isGpsOn = 0;//1;
    _isDebugOn = 1;//0;

    _isLedEnabled = 1;
    _isCayennePayloadEnabled = 1;

Modifications in SodaqOneTracker_v2/SodaqOneTracker_v2.ino

  1. Specify the ABP keys:
#define DEFAULT_DEVADDR_OR_DEVEUI "0000000000000000"
#define DEFAULT_APPSKEY_OR_APPEUI "00000000000000000000000000000000"
#define DEFAULT_NWSKEY_OR_APPKEY "00000000000000000000000000000000"
  1. Comment out everything in void loop() and put the following code there:
    //sodaq_wdt_safe_delay(15000);
    sodaq_wdt_safe_delay(10*60*1000);
    if (getGpsFixAndTransmit()) {
        setLedColor(GREEN);
        sodaq_wdt_safe_delay(800);
    }
  1. Comment out the filling of the GPS record in void updateSendBuffer() 
/*
         // Add GPS record on data channel 1
         float latitude = (float)pendingReportDataRecord.getLat() / 10000000.0f;
         float longitude = (float)pendingReportDataRecord.getLong() / 10000000.0f;
         float altitude = (float)pendingReportDataRecord.getAltitude();
         cayenneRecord.addGPS(1, latitude, longitude, altitude);
*/
  1. Leave only the following lines in bool getGpsFixAndTransmit() 
    // populate all fields of the report record
    pendingReportDataRecord.setTimestamp(getNow());
    pendingReportDataRecord.setBatteryVoltage(getBatteryVoltage());
    pendingReportDataRecord.setBoardTemperature(getBoardTemperature());

    if (params.getIsDebugOn()) {
        pendingReportDataRecord.printHeaderLn(&DEBUG_STREAM);
        pendingReportDataRecord.printRecordLn(&DEBUG_STREAM);
        debugPrintln();
    }

    updateSendBuffer();
    transmit();

    return true;//isSuccessful;
