If a Novatel device allows to enable a secondary AT command based
channel, then use that for device information, SIM handling, network
registration etc. and only leave the GPRS context setup to the first
command port.
The important part here is that the SMS atom needs to be on the second
AT command port since the main port doesn't handle sending correctly. It
never returns any success or error after the submission of the PDU.
Instead of using ofono_modem_set_powered(), use ofono_sim_inserted_notify()
which is the proper way to notify about sim state changes.
Now the problem is that voicecall commands fail with my Huawei E1552:
ofonod[12395]: > AT+CRC=1\r
ofonod[12395]: src/sim.c:ofono_sim_add_state_watch() 0x1bf8e50
ofonod[12395]: src/sim.c:ofono_sim_add_state_watch() 0x1bf8e50

ofonod[12395]: < \r\n^SYSINFO:0,0,0,0,255,,0\r\n\r\nOK\r\n
ofonod[12395]: > AT+CGMI\r
ofonod[12395]: < \r\nhuawei\r\n\r\nOK\r\n
ofonod[12395]: EventChannel: < \r\n^STIN:0,0,0\r\n
ofonod[12395]: > AT+CLCC\r
ofonod[12395]: < \r\n+CME ERROR: SIM busy\r\n
But as I can't make voice calls with this modem anyway, I don't worry
about them right now.
With Huawei E1552 I got sim busy errors when I plugged in the modem
and ofono was already running:
May 24 17:02:04 tukki ofonod[7619]: > AT+CRC=1\r
May 24 17:02:04 tukki ofonod[7619]: < \r\n+CME ERROR: SIM busy\r\n
May 24 17:02:04 tukki ofonod[7619]: > AT+CLIP=1\r
May 24 17:02:04 tukki ofonod[7619]: < \r\n+CME ERROR: SIM busy\r\n
Fix this by following sim state changes with ^SIMST notification and
only enable modem after SIM is ready. In case SIM is already ready
and we miss the notification for some reason, also use AT^SYSINFO
to check the state during enable phase.
Also change huawei_enable() to return -EINPROGRESS to make sure that
ofono modem is not powered too early. I believe this was a bug.
Adding a new notify function in the netreg atom for notifying a
received Network Identification and Timezone (NITZ) indication. This
data is consumed via a nettime plugin, of which there is also an
example.
Sometimes, Udev device 'remove' event could not report correct parent
node of current udev_device. Current code replies on the devpath
attached on the parent node to find modem and then remove it.
This fix is to change the way to store the devpath info into a
hashtable. So that we search hashtable to get devpath and remove the
modem.
The Wavecom WMP100 is a serial based modem, however it assumes CPIN to
be the final response. This requires some quirking in the sim driver.
