Hi!
I have problems with getting CNMA to work, so I'm exploring other
possibilities. Apparently ofono should be able to work without
that.. but is it working properly?
ofonod[5218]: < \r\n+CIEV: 1,3\r\n
ofonod[5218]: < \r\n+CIEV: 1,4\r\n
ofonod[5218]: < \r\n+CMTI: "ME",2\r\n
ofonod[5218]: drivers/atmodem/sms.c:at_cmti_notify() Got a CMTI
indication@ME, index: 2
ofonod[5218]: > AT+CMGR=2\r
ofonod[5218]: < \r\nOK\r\n
ofonod[5218]: > AT+CMGD=2\r
ofonod[5218]: < \r\nOK\r\n
ofonod[5218]: < \r\n+CIEV: 1,3\r\n
ofonod[5218]: < \r\n+CIEV: 1,4\r\n
So.... modem told us we have new message and where it is, but then
ofono ... deleted the message without delivering it...?
There's no new message@monitor-ofono...
Best regards,
Pavel

And this is quite reproducible.. It might be something power-management-related, I'm fighting with that a lot; but I believe modem is simply weird.

Would it make sense not to proceed with +CMGD in case modem did not provide a message for +CMGR? I don't think it is timing, as we see OK after CMGR... Fortunately, I found a mode that works...
