Hello.I am doing various tests to my project Arduino+GSM Shield+Sensor.This is the workflow of it:
1-Power apply to the prototype
2-After 2 minutes,GSM Shield send data from a sensor to pachube(xively) platform.
3-Every 30 minutes send data from sensor.
4-Disconnection from power source after 8 hours.
5-After 12 hours aprox. from disconnection, restart power to the prototype(Arduino+GSM+Sensor same time).
** It doesn't connect to xively and not send data.
The code in Arduino resets after x hours?
Thank very much.
