2. Turn WIFI ON and then WIFI OFF quickly (<2s)
3. Turn WIFI ON and then BT ON quickly (<4s)
4. Turn OFF BT
5. Turn OFF WIFI
6. Turn BT ON and then BT OFF quickly (<2s)
7. Turn BT ON and then WIFI ON quickly (<4s)

Evelyn, can you take to investigate?

[Evelyn Hung]

I'm wondering the build number, because we did blocking input when BT/WIFI is initialing, to prevent asynchronized states between device interface and UI. On my unagi with latest build, it's not possible to turn BT/WIFI on and off within 2 seconds, because we gray-out(disabled) the switch before getting the response from device interface.

Looking at the issue history, it was reported by Test on AU 156 [1], so that's:
gaia  @ 63f7b9ca0cacde
gecko @ 8dbe4cc16746bf

The gaia commit number is in nightly branch, there are 73 commits! Hard to identify which one causes the problem. :'(

But we know it's 2012-12-24 Gaia build.

I found easier STR.

STR:
1. Launch Settings app and choose Wi-Fi
2. Quick click on Wi-Fi toggle several times
3. Click the "<" to back to menu right previous steps
4. Enter Wi-Fi settings and trigger the toggle.

Expected Result:
*. The toggle can be triggered correctly

Actual Result:
*. The toggle is broken

Hi Al,

After the STR, the Wi-Fi toggle is really broken in B2G 2013-01-07-10-58-06 build.

Is Evelyn working on this bug? Could I take this?
Thanks. :)

I'm looking on this. I know how this happened but still figuring out it's a Gecko or a Gaia bug.

You could talk to Rudy or Evelyn later to see if they can redirect a bug to you.

I'm working on this bug. It's really an old problem that I'm trying to fix it for a long time.
This issue may need Gecko Bluetooth fix as well as Gaia writing settings fix. The problems are:
1. Bluetooth onadapteradded event didn't be passed to child process successfully.
2. Settings app didn't lock the UI on the right moment.

[Evelyn Hung]

I file a issue for Gecko fix: bug 827759. and keep this for Gaia fix which is locking Wifi/BT UI in the correct time.

This patch partially fix the problem here. We still need the patch of bug 827759 to completely fix the problem.
