[rilmodem] Not possible to get the IMEI without a SIM

[Evan]

I have a Nexus 4 (mako) without a SIM card. When I try to ask ofono for the IEMI, I don't get one back:

root@ubuntu-phablet:/# /usr/share/ofono/scripts/list-modems
[ /ril_0 ]
    Features =
    Emergency = 0
    Powered = 0
    Lockdown = 0
    Interfaces =
    Online = 0
    Type = hardware

It's definitely not busted though, as I can get it through other means:

root@ubuntu-phablet:/# od -j 0100000 -N 16 -c /dev/mmcblk0p19
0100000 x x x x 3 6 0 5 8 3 6 x x x x \0
0100020

This is known:

[13:16:43] <rsalveti> ev: it works fine, but you need a sim card atm
[13:17:05] <ev> rsalveti: hmm, why? The IMEI isn't tied to a SIM.
[13:17:16] <rsalveti> ev: I know, bug from our code
[13:18:11] <rsalveti> don't think we have one yet, we discussed it yesterday, and would need a few changes in ofono as we're not starting the modem if the sim card is not available (our current logic)

IMEI is exposed as the the top-level 'SerialNumber' property. I'm currently working on an update to the ofono/rilmodem code which should provide 'SerialNumber' on supported RIL-based devices irregardless of SIM availability. I just confirmed that this works on maguro sans SIM.

Here's the output of 'list-modems' on the device mentioned above on comment #1:

root@ubuntu-phablet:/usr/share/ofono/scripts# ./list-modems
[ /ril_0 ]
    Features =
    Emergency = 0
    Powered = 1
    Lockdown = 0
    Interfaces = org.ofono.VoiceCallManager
    Online = 1
    Model = Fake Modem Model
    Revision = I9250XXLA2
    Type = hardware
    Serial = 351746051290297
    Manufacturer = Fake Manufacturer
    [ org.ofono.VoiceCallManager ]
        EmergencyNumbers = 08 000 999 110 112 911 118 119

FYI, the device serial number can be grabbed from the Android property 'ro.serialno'.

This bug was fixed in the package ofono - 1.12+bzr6836-0ubuntu1

---------------
ofono (1.12+bzr6836-0ubuntu1) saucy; urgency=low

  [ Ricardo Salveti de Araujo ]
  * Changing packaging tree to make it part of the daily CI jobs
    - Changing source format to 1.0 (required by CI)
    - Creating bzr bd compatible branch, with the same content as available in
      the previous package

  [ Tony Espy ]
  - Ensure that *netreg_data is always set in callback data (LP: #1234491)
  - Re-factor rilmodem initialization code to enable set online/offline
    (LP: #1210502)
  - Fixing parcel parsing when probing for mute.

  [ Mathieu Trudel-Lapierre ]
  * Make the package use bzr-builddeb split-mode to properly build the source
    tarball.
