SIMCOM SIM900 GSM GPRS w/Arduino
Posted: Sat Jan 31, 2015 4:01 am
Hello guys!
My hardware is:
1) SIM900 GSM GPRS shield
2) XDRduino UNO
My software is:
"C:\Program Files\Arduino\libraries\GSM\examples\Tools\TestModem\testmodem.ino"
- an example tool from arduino library.
My problem is:(COM PORT received data:)
Starting modem test...ERROR, no modem answer.
Checking IMEI...Error: Could not get IMEI
My question is:
1) How to set jumpers X1 "Xduino", "RX", "07(RX)", "SWserial","08(TX)"
2) Power switch can be set to ext(external supply present) or Xduino(USB) - OK.
3) 3V CR1220 is absent on my plate. is it OK?
4) what I should do? Have you any simple test to test the plate?
