sim508 evaluation board
HI
I am using the SIM508 with its evaluation board.
I developed my controller board and test in lab and could send data to server.
When I try to test in CAR, the evalboard resets after command AT+CIICR
in the LAB the power supply was 2A@12V
in the car I use the 12 Volt direct form the battery but it's not working the car battery is 45A.
I face the same problem when I try to Power up the system from 9V Alkaline battery
So what's the problem?
