Hi, I am trying to interface L89 GNSS module with Arduino board and getting the desired outcomes. Now I wanted to pass $PSTM commands to switch between constellations but I do not have any idea how to do it in Arduino board. Can you suggest me something?
Hi Nikhil
- Please use the serial port tool on the PC to directly send commands to L89 to ensure that the command can be sent successfully.
- Connect L89’s UART through Arduino’s UART, and refer to the protocol document for the command format.
