    I’m trying to get my dragonfly to send an SMS message and I’m having some issues.

    I’m using:
    Dragonfly_Cellular_SMS_Example
    https://developer.mbed.org/teams/MultiTech/code/Dragonfly_Cellular_SMS_Example/

    I’m getting this message across debug port (I’ve removed my cell phone number):
    [INFO] initializing cellular radio
    [INFO] setting APN
    [WARNING] sendCommand [AT+CMGS=”+1xxxxxxxxxx”,145] timed out after 2000 milliseconds

    main.cpp has line “radio->sendSMS(msg)”

    I’m finding sendSMS at line 254 in Cellular.cpp. It calls sendCommand, which I’m finding at line 170 in Cellular.cpp. A final check at line 245 is what generates the timeout message on the debug port. The timeout has to do with getting a response from the Telit module, and if it doesn’t get a response it sends out the message seen above.

    I’ve also tried VVV_MultiTech_Dragonfly_ATT_Dallas. I basically get the same error message.

    I’ve tried running the YYY_Dragonfly_USBTerminal and sending AT commands. It appears that my SIM is connected to the network.

    It seems like my .bin file was correctly programmed in. My debug port is working. The micro is responding. SIM appears to be connecting to the network.

    What do I look at next? I’m not sure what would cause the message I’m getting.

    Are you able to send an SMS message using AT commands?

    at+cnmi=2,2,0,1,0
    at+cmgf=1
    at+cmgs=”+1 YOUR PHONE NUMBER”

    You’ll get an extra prompt. Type your message then press control-z to send.

    If the SIM has data service, does a ping work? Try

    at#sgact=1,1
    at#ping=”www.google.com”  
    at#sgact=1,0

    Here is what I got:

    at+cmgf=1

    at+cmgs=”+1xxxxxxxxxx”
    > Test message
    +CMGS: 72

    OK

    I didn’t receive the text. I tried it again with my wife’s number and didn’t receive the text.
