SMS Timeout

[Mike Meyer]

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.

at
OK
at+ccid
+CCID: 89011702272024881861

OK
at+creg?
+CREG: 0,1

OK

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
OK
at+cnmi=2,2,0,1,0
OK
at+cmgf=1
OK
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.

at#sgact=1,1
#SGACT: 10.161.98.28

OK
at#ping=”www.google.com”
#PING: 01,”172.217.3.164″,28,51
#PING: 02,”172.217.3.164″,2,51
#PING: 03,”172.217.3.164″,2,51
#PING: 04,”172.217.3.164″,2,51

OK
at#sgact=1,0
OK
