We need solid base to enable BT API v2 support. need unit test as well

Fred, https://wiki.mozilla.org/index.php?title=Gaia/Team/Taipei&oldid=1047643#Fred Why is this bug listed on the wiki but with no updates for a month?

The main PR is blocked on test and will continue the test when Bluetooth APIv2 paring is ready. There are several discussions, experimental branches, related bugs around this bug in a month. Most work are forked to unblocked this issue. I'll update and link them accordingly to this bug to keep information synced.

Some experimental PRs: Bug 1116437 - [Bluetooth] promisify Bluetooth getadapter https://github.com/mozilla-b2g/gaia/pull/27059 to move adapter into promise format lazyload bluetooth To use same window.bluetooth domain for v1/v2 support https://github.com/mozilla-b2g/gaia/pull/27057 Bug 1090799 - move nfc related bluetooth to separate module To cleanup nfc/bt misery but may leverage george's nfc_core refactor work https://github.com/mozilla-b2g/gaia/pull/27003

From today I will start the v2 BT file receiving test (send from android because it allow send file without paring first)

Successfully got picture from samsung android device to flame with APIv2 (with ian's BT/Settings app patch)

The current patch remove the NfcHandoverManager dependency parts to make test work. To test on device, you need apply settings patch first curl https://github.com/mozilla-b2g/gaia/pull/26139.patch | git apply Current gaia master must work with flame 18D image.

The bluetooth.js part would be done in bug 1088591, which fix the quick settings issue in v2

The bluetooth_transfer.js part could be resolved by bug 1116437. work based on bug 1128812, make getadapter return promise allow v1/v2 share same bluetooth_transfer.js, test on device ok.

since we decide not expose getAdapter function with BT APIv2, the bug 1116437 patch is obsolete. Will implement new v2 bluetooth_transfer here based on bug 1128812

Is this bug still valid?

Both transfer and receive works after system bug 1142371 resolved & BT app support getAdapter via V2 API
