AT+CNMI=1,2,2,1,0
< OK
Well you can try to see what Android is doing for SMS with:
# echo 0x7fffffff > /sys/module/ts27010mux/parameters/debug_level # dmesg | grep ts27010 | grep ATTo send SMS, looks like Android RIL first does:

2 AT+CMGS=327 where 327 seems to be the size of the whatever encoded message. Then the next packet to dlci 2 contains the encoded message that is of size 327.
Sending SMSes seems to work with ofono.
OK is this over ttyUSB or ngsm port?
ttyUSB. ngsm port behaves too strangely for me.

When receiving, mdm6600 sends these on dlci 1:
~+WAKEUP
~+WAKEUP
~+WAKEUPThen mdm6600 sends this on dlci 9:
~+CMT=372And that's probably the incoming SMS size. But I don't see anything for what actually reads the incoming SMS.
Hmm it occured to me that maybe the incoming messages are read using QMI over USB.

That seems to be standard message ftp://www.3gpp.org/tsg_t/TSG_T/TSGT_04/Docs/PDFs/TP-99129.pdf .

Do you see AT+CNMI during boot and AT+CNMA after message is received?
I'm only seeing AT+CNMA=0,0 on dlci 9 after resume. I think that is used to query for new messages.
No CNMI in my logs it seems. But if QMI over USB is used to read the messages that would explain it only checks for new SMS.
Thanks for info. No real leads there :-(.

I tried debugging this some more, and it is rather frustrating :-(.
State of the modem is kept over tries, which makes me reboot rather often.
Is there way to power cycle the modem without reboot? That should make the debugging... less bad.
Best regards,
Pavel
