The simplest is probably the OsmAnd protocol.
@Meir99
LBS is very inaccurate
Thank you for replies.
@Anton Tananaev
I am familiar with OsmAnd protocol. But never saw LBS parameter in string.
@Track-trace
No need accuracy just know roughly where. No GPS modules on the PCB..
We do support cell and wifi for it. Check the protocol decoder.
Hello I have few units of a IoT temperature and humidity sensor device over GSM. I am wiling to use it as LBS tracker, no GPS module on board. Which protocol is best to use in order to track on Traccar. I have source codes and compiler of the board ,I can change the firmware codes and download into MCU.
Thank you
