A7670SA-FASE NMEA Parsing error TinyGPSPlus #80

Closed AlverGant closed 8 months ago

AlverGant commented 8 months ago

Hi,

Please help.

I have the following modem: Manufacturer: INCORPORATED Model: A7670SA-FASE Revision: A011B04A7670M7_F A7670M7_B04V02_220927 QCN: IMEI: 869731059073809 MEID: +GCAP: +CGSM,+FCLASS,+DS

I am trying to parse GPS data and it appears the modem is spilling a correct NMEA but parsing with https://github.com/mikalhart/TinyGPSPlus is giving me wrong coordinates...

Here is my startup GPS code

modem.sendAT("+CGDRT=4,1"); modem.sendAT("+CGSETV=4,0"); modem.sendAT("+CGNSSPWR=1,1"); modem.sendAT("+CGPS=0"); modem.sendAT("+CGNSSMODE=3"); modem.sendAT("+CGPSNMEA=1,1,1,1,1,1,0,0"); modem.sendAT("+CGPSNMEARATE=2"); modem.sendAT("+CGNSSTST=1"); modem.sendAT("+CGNSSPORTSWITCH=0,1");

AT+CGNSSINFO +CGNSSINFO: 3,15,,05,07,22.9284973,S,43.1748390,W,190124,064019.00,110.3,2.196,,18.29,10.06,15.28, OK

But parsing with modem.getGPS(&lat, &lon) gives me wrong coordinates Latitude: -0.116667, Longitude: -0.000000

Also modem.getGPSTime(&year, &month, &day, &hour, &minute, &second) is giving me the wrong date Date: 2124-19-00, Time: 06:40:22

What could be wrong here

A011B04A7670M7_F This version of GPS should not have problems. I checked that the location you provided should be correct. Please try to use the NMEA Parse example I provided for testing. https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/tree/main/examples/GPS_NMEA_Parse

Thank you @lewisxhe for the prompt return

I am trying to compile your code having added:

define LILYGO_T_A7670

define TINY_GSM_MODEM_SIM7600

But I am encountering issues with the gps library: Compilation error: 'TinyGsm' {aka 'class TinyGsmSim7600'} has no member named 'setGPSBaud'; did you mean 'setBaud'?

Please what gps library are you using?

Best regards

lewisxhe commented 8 months ago

Are you using the previous example? Please see README and reinstall TinyGSM in the warehouse. Do not use upstream TinyGSM. Upstream TinyGSM does not support A7670.

Thank you again @lewisxhe that was my problem indeed.

Your code is working!

Will integrate it into my code

Um . I added many useful examples that you can test and if the problem is solved please close it
