interesting question.
I use only bike gps TK906 with watch protocol and it work not so good.
Mirko What do you mean that is not working so good? you re not watching it in a traccar server or the signal is not stable?
there is a problem with the message length. tracecar server and signal is fine!

hope you have better luck with the tracker, give him a try
Mike sorry for my bad english , i dont understand the problem with message length.
So i have one question
Are you tracking your bike using that GPS Model and you re watching it at traccar without any problem?
I would like to use it in Colombia
No problem!
I do have problems with the tracker....sometimes - not everytime the tracker send wrong length data, so traccar will discard it.
With programming knowledge and the will to do it is possible to fix, i think.
If you have GPS and mobiledata SIM you can use it everywere :)
Thank you Mirko , is good to know it , so you can recommend it , Dont you know anything about smart watch for kids or old people?
