Hi,
I use an UNO R3 with SIMCOM GPRS shield and Ublox Neo-6m GPS for SMS based car tracing. Now I'm in testing period and I test my UNO with external power supply. It's working well some hours. After 3-8 hours the UNO doesn't answer the SMS request. If I restart (sometimes not enought one time) it working corretly again. Do I need some kind of restart after an exact time period?
I tested it to further. The stopping is not based on time. The device stops after 5-9 SMS received and I have to re-upload the code for work again.
