Re: [b2g] (mozBluetooth|mozWifiManager).setEnabled() and mozSettings

[Gene Lian]

Tim,

This is an existing issue. Please see https://bugzilla.mozilla.org/show_bug.cgi?id=729877. I'm just taking this one (for the Wifi part). Hopefully, it can be done in 1~2 weeks.

Thanks,
Gene

Gene, Kaze, Evelyn,

We just have a offline discussion about this.

Gene will be working on the bug to allow wifiManager to consume
mozSettings value directly. In the mean time, Evelyn will deliver a
Gaia change that (A) actually ask Settings app and Quick Settings in
System app to respect the mozSetting value, and (B) sync that value
from mozSettings to wifiManager in System app.

The part (B) will be removed once Gene's platform fix is delivered.

Kaze, Evelyn is working on wifi part of the Settings app extensively,
so you might need to hands off from there now.

Correct Evelyn's email address :-/

[Evelyn Hung]

I found there is an updated version of the wifi in Setting app (from Kaze),
I'm trying to merge now.
