Has anyone played with the SM5100B quad cell module? I have a Sparkfun CEL-09607 adapter board and module. They have some documentation including a 141 page command manual, but no luck getting the module to send a text message.
I have a level shifter (the module is 3.8v) and can talk to it through RealTerm on my laptop. I have a working SIM card for data. When I turn it on, I get all the correct commands back. I set it in the text mode (AT+CMGF=1): that is OK. I send "send a short message" (AT+CMGS=(a phone number here).. It is still happy and sends back a ">" which means "enter your text now"... I enter text (example: hello test) followed by a control z... Now it just locks up....
Has anyone played successfully with one of these modules? Am I doing something wrong?
Thanks,
Jim
