The next time you receive the +CMS message, terminate the smsbox and
bearerbox. Connect to the Siemens M20 using minicom or kermit.
Check and see if it can respond to any AT commands. Try the following:
- ATE1
Turns echoing back on since Kannel turns command echoing off during
initialization. Reponse should just be "OK".
- AT+CMGF?
Returns info about whether the modem is in TEXT or PDU mode. This
should be set to 0 (PDU).
- AT+CPMS?
Returns info about how your messages are stored and if you have
any messages in the storage memory. The info should be something
like:
+CPMS: "SM",0,20,"SM",0,20
The "SM",0,20 means:
"SM",0,20
^ ^ ^-- Maximum capacity for the memory store is 20 messages.
| +----- There are no messages in the memory store.
+--------- Read, list, delete message stored in SIM memory.
I have found that three situations that cause errors during sending using
a GSM modem:
1) AT+CMGF switches to 1 (TEXT mode)
2) GSM modem does not handle unsolicited SMS the way kannel wants it
to behave. +CNMI cannot be set to 1,x,x,x,x on some modems
(WAVECOM-based). Instead, it can only support 2,x,x,x,x
(unsolicited responses go to storage memory).
3) Carrier network's signaling channel was congested.
To rectify 1), I modified smsc_at2.c to execute an "AT+CMGF=0" before
any sending (+CMGS) or reading (+CMGR) from the GSM modem.
For case 2), I added code to smsc_at2.c to check for a "+CMTI:" response
from the modem. +CMTI indicates there's an unsolicited response from
the modem. The message store and message storage number follows the "+CMTI:".
I made smsc_at2.c read the unsolicited message from the message store.
For case 3), I added code into smsc_at2.c to pause if the first attempt
was not successful.
See ya...
