Hello,
a question for specialists / hardware coders. There's a tiny mobile GPS tracker on the market (obviously made in China) named ZX612, ZX613, ZX302 etc. They use the MT6261D or MT2503D chip which seems to be pretty well documented (as far as my quick google searches say). Reading roughly through the papers, I am really impressed what this tiny thing can do ...
The tracker is programmed to use a SIM-card to make a connection to the network, wait for incoming messages / calls and do whatever it is asked for. Example: you send a message with 999 and the tracker "wakes up", finds gps-position and replies with a message containing the coordinates.
I would like to change the behavior of the device. Actually no, I am looking for someone who can do this. How difficult is it? Who can do it?
Here's a link to the tracker hardware with some details on parts & features:
