I bought SIM868 breakout board with GNSS support. https://www.aliexpress.com/item/33013782111.html
However, I can’t get coordinates using standard at-command AT+CGNSPWR=1, AT+CGNSTST=1, etc. I get “+CME ERROR: unknown” all the time. I tried commands for GPS also, in case if seller was not exact. Does anybody know how to get location with this kind of module? PS. There are also extra UART pins for GNSS. As far as I know, there is is an alternative way to work with GNSS, however It will make to remove two resistors, what I don’t want to do.
