Hi everyone,
I have waveshare sx1302 LoraWAN gateway hat https://www.waveshare.com/wiki/SX1302_LoRaWAN_Gateway_HAT which comes with the GPS module Quectel L76B-M33 Q1-A7861 and hat is connected to raspberry pi 3b as a device /dev/ttyS0 and if i see data coming from this device i dont see GPS time of week in milliseconds, so i wanted to query if there is any other specific command needed for this and how to use that command basically i need that time for crystal correction.
Thanks
Adding one more thing on serial port /dev/ttyS0 i can see various NMEA sentences coming starting with GNGDA, GNRMC, GNVTG, GNGGA, GPGSA, BDGSA, GPGSV, GPGSV, BDGSV ..etc.
Hi @john3
Our module doesn’t output GPS TOW data.
it can be converted using RMC UTC data output by our module.
I will send an email regarding the code and the explanation for the following NMEA messages you have asked on the follow up questions
Thank you
