Is there the protocol for the tracker 311b device?
Do you have the protocol documentation? I can't really find any matching protocol.
I don't have it...
but with your hexadecimal,
is reading the imei of the device
when sending the SMS, check123456 gave me this:
311-L-2_V1.06_220715
Try 5001 i had some of then and they are smallers tk103 use gprs123456 after programming
I also tried, with a 303 device...
but when sending the check command, notice that it says "baanool" , as if they updated the tracker devices
the port? in 303 is 5001 10% sure i use it everyday
Apparently a new protocol came out, "baanool", which has the same name as the models we already use.
Because I have tried all the ports of the clone devices
and it doesn't work with any of them
I have had several of that brand, xexun and coban sell them by lot and they put their brand in the box and the check as well as their ip, but they have always worked with traccar, if you want try these sms and confirm and post the answers
adminpassword13142324 the answer will be password123456, this will delete it and reset it completely
version123456
imei123456
check123456
With that, I could help you a little more.
Try the ports for clone devices.
