sim508 interfacing
Hi ALL,
I try to send AT commands using microcontroller to the SIM508 EVB but it don't respond and I find disturbance in the behavior(appear in the status leds).
when I use the pc to simulate the board behavior it work well, also interfacing the board with the PC and sending AT commands work well.
note: in some cases I may notice the disturbance just during connecting the serial cable or connecting the power to the microcontroller board.
I hope some one respond soon.
THANKS
Fayek
