Which binary protokoll for a own DIY-device?
Why just a binary protocol?
A text system could achieve every position with less than 200 bytes (and you could use a well documented existing system)
Okay, but do you know any easy protokoll .... with a sample how to use with Arduino?
I use the Queclink Air Interface Protocol, which is supported by Traccar.
You do not need to implement the whole protocol. RESP:GTFRI in Section 3.3.1 (page 112) is all you need for position reports.
Hello,
I'm using the DIY-GPS Device "TTGO SIM7000G" - with a ESP32 and GSM modem.
It is running with own arduino script in the 2G-band & with the "OSMAND"- Protokoll very well (Port 5055, HTTP GET).
But I am using a HOLOGRAM-International SIM with a MAKE-Account (1MB for free). Every Position cost 2.74KB of my data, this means approx. 10 positions a day.
Is there any easy to implemend binary protokoll to send a position? How can I save data?
Thanks, Ralf
