I have this GM862 module which I’d like to connect it to my MCU board. I want the MCU to collect data from the GPS receiver and store them on its flash. I guess I can do it via the IIC, SCI or the CAN interface of my board. I am not sure which one is best way. Also, do I need to send commands like “AT$GPSACP” to the GM862 to collect the commands? I appreciate some hints to jump start my approach.
