I have used a GPS & 4G module (QUECTE EC21-EC), it is mounted on the device and runs OpenWRT.
1 / For 4G, it works OK
2 / For GPS, I don't know if there are any missing commands (I also have used some command lines), even though I have searched for some guide information available on Google. I need your help:
- How do I use the command line to send LAT, LONG to the central system?
- Or do I have to do anything else for this?
Thanks in advance,
