I recently purchased a GPS / GSM tracker. The device has a built in vibration sensor (not sure what type - possible accelerometer).
I would like to provide an external logic input (switch etc) so that I could trigger the "send sms" functions at will. This normally only triggers when vibration is detected, or if I text it a set numeric (8880000). I would also like to re-program certain elements (if possible) so that I can control the output SMS - currently returns a string pointing to a chinese GPS website. I would just like a the coordinates, no URL.
The first step is trying to figure out how this device works - hardware used, language used, ROM, sensor(s) used and way to capture or override their output.
