Polling a GPS module

NEMA input commands

Hi @rgsparber , Please tell us which M10 document you are looking at. I couldn’t find Table 2-4 that you mentioned. Please also tell us which Pro Micro board you are using. There are several. Most are 3.3V, but some older ones are 5V. Please be careful. The u-blox MAX-M10S is 3.3V. You may hit problems if you are using a 5V Pro Micro. I’ve put together a generic NMEA polling example (see below). It will set the rate of the standard NMEA messages to zero, using the UBX VALSET configuration interface. Then it polls GNGGA using the xxGNQ message. All of the bits you need are in there; there is code to calculate both the UBX and NMEA checksums (they are different). I hope this helps, Paul // Communicate with the u-blox MAX-M10S over Serial (UART) // Set the rate of the standard NMEA messages to zero // Poll individual NMEA messages #define myConsole Serial // Change to e.g. SerialUSB if needed #define mySerial Serial1 // Change this if needed void ubxWriteByteUpdateChecksum(uint8_t…

I hope this helps,
Paul
