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.

Some modems get confused by the CSIM commands and reply with an error,
which we treat as sim not inserted.
|
|
|
|
These modems don't support voicecall anyway. Recommended by Denis.

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+CME ERROR: SIM busy\r\n
ofonod[12395]: > AT+CLIP=1\r
ofonod[12395]: < \r\n+CME ERROR: SIM busy\r\n
ofonod[12395]: > AT+COLP=1\r
ofonod[12395]: < \r\n+CME ERROR: SIM busy\r\n
ofonod[12395]: > AT+CCWA=1\r
ofonod[12395]: < \r\n+CME ERROR: SIM busy\r\n
ofonod[12395]: drivers/atmodem/voicecall.c:at_voicecall_initialized()
voicecall_init: registering to notifications
ofonod[12395]: src/sim.c:ofono_sim_add_state_watch() 0x1bf8e50
ofonod[12395]: > AT^SYSINFO\r
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.

Tested with Huawei E1552 HSDPA USB stick using a finnish Saunalahti prepaid
SIM.

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.
|
|
To avoid the race condition that modem is registered before we retrieve
the data device property.

Dell 5530 seems to have three tty ports labeled:
"Dell Wireless 5530 HSPA Mobile Broadband Minicard Modem"
"Dell Wireless 5530 HSPA Mobile Broadband Minicard Modem 2"
"Dell Wireless 5530 HSPA Mobile Broadband Minicard GPS Port"

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.
Refer to commit 6d28f82dc1ccb3de3a028a88eafb96fb001c7e61 for details.

Seems that polling support in phonesim is less than working

This is not official oFono API

Add ofono_sim_inserted_notify function to notify the core of SIM
insertion / removal.
Make every plugin generate a sim inserted event on start. For devices
with removable card, the event should be emitted after the
plugin detects such event. For devices that need to wait for SIM card
initialization, they can emit this event later.

The second port might be used for a second active context via ppp

With V1 parser the driver fails to detect when a SMS is successfully
sent and keeps re-trying until Max retries.

Comparing with general Huawei modem, EM770 is a full feature modem that
supports voicecall, phonebook, call forwarding, call barring, etc.
