[Bug 1442962] Re: Dialer app reports "No network" even though cellular is connected

 

So, the problem here is that mission-control now uses an internal
account property (always_dispatch) to control the account availability
when there is no network. Previously this behavior was completely
disabled with a dconf key, which was triggered by the ofono-setup script
(the one responsible for creating the accounts during startup)

Unfortunately there is no way to set the always_dispatch property via
mc-tool, so it make it impossible to continue using ofono-setup to
create the accounts. After a discussion with boiko we agreed the
approach taken by jolla with telepathy-ring was the right way to go.
They have a mission-control plugin that provisions the accounts and also
set all the required properties (including always_dispatch=true). This
approach will avoid having duplicate accounts (a bug we fixed some weeks
ago) and make sure we will always have the right number of accounts (one
for each sim slot).

The plugin is in a separate package as it only makes sense to have it
installed on devices with ril modems, this way it can be pulled by
another package (not sure which yet) for each specific device as needed.

  Dialer app reports "No network" even though cellular is connected

Bug description:
  current build number: 165
  device name: m75
  channel: ubuntu-touch/vivid-proposed
  last update: 2015-04-08 05:43:13
  version version: 165

  It happens almost daily to me that the dialer app decides that there's
  no network available. Indicator says the correct network is connected,
  and I can even use GSM data, but no telephony apps work.

  When this happens, my `mc-tool dump` looks somewhere along the lines
  of (this is modified from memory, will update when happens again):

       Account: ofono/ofono/account0
  Display Name: Nju
       Enabled: enabled
          Icon: im-ofono
      Connects: automatically
       Service: ofono

  Presences:
     Automatic: available (2) ""
       Current: offline (1) ""
     Requested: available (2) "online"
      Changing: yes

        (string) modem-objpath = /ril_0

  Stopping/starting the dialer doesn't help, only thing that does is
  killing mission-control (or well, restarting lightdm or the phone).

  Please let me know what else to collect when this happens again.
