Passing $PSTM commands to Quectel L89 using Arduino

IoT Modules GNSS Module

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

  1. Please use the serial port tool on the PC to directly send commands to L89 to ensure that the command can be sent successfully.
  2. Connect L89’s UART through Arduino’s UART, and refer to the protocol document for the command format.
