I am using the GSM Module from Itead studio. I cannot get it to register on the GSm network,
This is the module:
The response I get in the serial window is:
system startup GSM doesn't response Registration 0
and in the arduino software:
Error inside Serial.serialEvent() java.io.IOException: Bad file descriptor in nativeavailable at gnu.io.RXTXPort.nativeavailable(Native Method) at gnu.io.RXTXPort$SerialInputStream.available(RXTXPort.java:1532) at processing.app.Serial.serialEvent(Serial.java:215) at gnu.io.RXTXPort.sendEvent(RXTXPort.java:732) at gnu.io.RXTXPort.eventLoop(Native Method) at gnu.io.RXTXPort$MonitorThread.run(RXTXPort.java:1575)
it seems that its not able to register on the gsm network.
Any help would be great. I am giving up and consider the SIM900 package on the module to be broken and i dont think its worth buying another.
