Issue Setting Up RTK with SparkFun LG290P GNSS Modules

GPS/GNSS
1

Setup:
We connected two SparkFun LG290P Quadband GNSS modules through UART3.

From the default values:

  1. Set the base GNSS to base mode with:
    $PQTMCFGRCVRMODE,W,2
  2. Changed the baud rate of UART3 to 115200 with:
    $PQTMCFGUART,W,3,115200
    (as we are planning to use the SparkFun LoRaSerial Kit – 915MHz to send the RTK corrections, and the maximum baud rate is 115200).
    3.Configure the base station to Survey-in mode
    $PQTMCFGSVIN,W,1,60,15.0,0,0,0*3E
  3. The baud rate of the rover has also been changed to 115200.

Each module is connected to a separate antenna.

Current Situation:
The RTK LED is blinking, but we receive the following errors:

  • On the base board: $PQTMVER,ERROR,3
  • On the rover board: $PQTMVER,ERROR,3

Any suggestions?
