    • RE: GPS acquisition doesn't work on T-A7670E with GPS

      Hello all,

      It seems I am alone trying to debug my issue 😉

      I have found at least one of the source of the problem, which was coming from the fact the TinyGSM library was actually updated only for T-SIM A76XX series, available on github but NOT on the TinyGSM library Github as one could guess.

      The updated TinyGSM library is located in one of the subfolders of the T-SIM A76XX series github. Accessible through download and erase of the library distributed over internet. A regular update of the library would be x1000 times better and would have saved me at least 4h of chaotic troubleshooting 😞

      However, my GPS does not work yet (even if this time, the enable function works correctly and the examplary code provided runs without error...)

      Any clue on best parameters to use and optimize GPS acquisition would help ...

    • RE: GPS acquisition doesn't work on T-A7670E with GPS

      After some more debugging it appears that my GPS simply does not enable when running the modem.enableGPS() function.

      Here is my modem name : Modem name : A7670E-FASE
      Here is what I have in the AT command dump :
      AT+CGPS=1

      ERROR

      In the "Builtin_GPS" example provided on Github, the modem.enableGPS function is used with a PIN int passed as argument :

      modem.enableGPS(MODEM_GPS_ENABLE_GPIO)

      however when I compile the code with the PIN passed as an argument, I receive the following error "error: no matching function for call to 'TinyGsmSim7600::enableGPS(int)'

      So everything seems like the GSM_SIM7600 is not the right modem... but even looking in the TinyGSM library I cannot find the modem for T-SIM A7670...

      Can someone please help??

    • GPS acquisition doesn't work on T-A7670E with GPS

      Hello
      I cannot find a way to acquire GPS data from my T-A7670E board (equipped with GPS)

      When I use examples available on github, I get the error that my "modem does not exist" when the following modem is selected : #define TINY_GSM_MODEM_A7670

      Github example I am using is : https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/examples/GPS_BuiltIn/GPS_BuiltIn.ino

      When I replace the modem by #define TINY_GSM_MODEM_SIM7600, all functions work fine (including 4G communication) but GPS data remains unaccessible (attempts to run modem.getGPS() function but data never comes)

      Can somebody let me know a "working" sketch using GPS on T-SIM A7670E?
      The one on github does not work!!

      Thanks a lot
      Guillaume
