Hi All,
I did some tests with the following setup:
- Meego Netbook 1.0.x
- ofono git (1.9.2010)
+ Patch "[PATCH 1/2] huawei: poll sim state" from Kalle
- connman git (31.8.2010)
+ Patchset "[ofono-refactor-v2 PATCH xx] oFono API breakage, take 2"
+ Patchset "[service-leak PATCH xxx] fix service leak"
- EeePC 1005HA
- Huawei K3715 (Vodafone Mobile Connect USB)
- Huawei E172 (Vodafone Mobile Connect USB)
Below is a summary of the results. I have separate logfiles for each
test run with "OFONO_AT_DEBUG=1 ofonod -n -d '*'" output. Shall I post
them here?
Please let me know what I can do to improve the Huawei support.
Thanks to Kalle and Pekka for helping out on IRC.

Test run 1: Huawei K3715 with unlocked SIM (no PIN required)
================================================================================
1. Start ofonod after modem has settled
-> Everything is fine
-> Modem shows up in connman
2. Unplug / plug
-> First sysinfo shows sim_state: 0
-> Later sysinfo calls return sim_state: 1 (checked in Minicom)
-> Modem not detected in connman
3. Unplug / plug
-> same as 2.
4. Unplug / plug
-> same as 2.
5. Unplug / plug
-> same as 2.
Summary: Modem only works if already settled before ofonod starts.
Test run 2: Huawei K3715 with locked SIM (PIN required)
Note: Whenever a "PIN required" showed up, I used the "tests/enter-pin"
script.
================================================================================
1. Start ofonod after modem has settled
-> Everything is fine
-> Modem shows up in connman
2. Unplug / plug
-> same as 1.
3. Unplug / plug
-> enter-pin throws "DBus.Error.NoReply" exception
-> Modem not detected in connman
4. Unplug / plug
-> same as 3.
5. Unplug / plug
-> same as 1.
Summary: Modem works if already settled before ofond starts and
sometimes when plugged in.
Test run 3: Huawei E172 with unlocked SIM (no PIN required)
================================================================================
1. Start ofonod after modem has settled
-> Everything is fine
-> Modem shows up in connman
2. Unplug / plug
-> First sysinfo shows sim_state: 255 (handled by Kalles patch)
-> Next SYSINFO shows sim_state: 1
-> Modem not detected in connman
3. Unplug / plug
-> First sysinfo shows sim_state: 255
-> Next SYSINFO shows sim_state: 0(!)
-> Then a SIMST reply comes in (not there in 2.)
-> Modem not detected in connman
4. Unplug / plug
-> First sysinfo shows sim_state: 255
-> Next SYSINFO shows sim_state: 0(!)
-> No SIMST reply
-> Modem not detected in connman
5. Unplug / plug
-> First sysinfo shows sim_state: 255
-> Next SYSINFO shows sim_state: 1
-> Modem shows up in connman
Summary: Modem works if already settled before ofond starts and seldom
when plugged in. Several different behaviours are observed.
Test run 4: Huawei E172 with locked SIM (PIN required)
Note: Whenever a "PIN required" showed up, I used the "tests/enter-pin"
script.
================================================================================
1. Start ofonod after modem has settled
-> Everything is fine
-> Modem shows up in connman
2. Unplug / plug
-> AT chat gets out of sync early (no "right" reply after ATE0)
-> Modem not detected in connman
3. Unplug / plug
-> same as 1.
4. Unplug / plug
-> same as 1.
5. Unplug / plug
-> First sysinfo shows sim_state: 255
-> Next SYSINFO gets no reply
-> This happened quite often in other tests. The modem is still
delivering replies to previous commands and the SYSINFO
request seems to get lost.
-> Modem not detected in connman
Summary: Modem works if already settled before ofond starts and seldom
when plugged in. Several different behaviours are observed.
