IRC

You can find us on the IRC server irc.mozilla.org, channel #fxos-comms(There is no specific channel for network-alerts, but you could still find devs here).

Filing bugs

You can file bug on Bugzilla. Please include the Firefox OS version you use, and possibly a screenshot or a video.

Debugging with emulator

Firstly you will need a emulator build to run the emulator and enter the command "cbs pdu [PDU_HEXSTRING]" for firing the fake alert message. Here is the example:

cbs pdu C0021112011154741914AFA7C76B9058FEBEBB41E6371EA4AEB7E173D0DB5E9683E8E832881DD6E741E4F7B9D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D100

The bold "1112" is the message identifier and this ID represents different channel. Please reference |9.4.1.2.2 Message Identifier| in spec.

The alert message structure

Please reference the CellBroadcast in gecko layer

Some future development

Handling all alert message in network-alerts app

• bug 1093922: Currently we only handled CMAS message in network-alerts and handled rest of cell-broadcast messages in system app cellbroadcast module. In long term we will need to remove this module from system and handle all the alert message in network-alerts app.
