Currently in Settings/Bluetooth, we do defaultAdapter.connect(device.address, 0x111E); to connect with remote Bluetooth headsets. The magic number 0x111E is actually the UUID of Handsfree profile (HFP). This works well when the target Bluetooth headset supports HFP. However, there is another Bluetooth profile used in some headset models called Headset profile (HSP, UUID 0x1108). With current implementation, we have no chance to establish a HSP connection with those HSP-only devices. Moreover, to do Bluetooth HSP certification test, we have to modify 0x111E to 0x1108 manually. We should check do something like "Try HFP first, if an error is returned, check if the reason of the failure is 'the remote device doesn't support HFP'. If it is, then try HSP".

Nominate as tef+ since we want Bluetooth HSP certification could run smoothly.

Yes it does. Like I said, we have no way for partners to test HSP unless they modify settings/bluetooth.js on their own.

per comment 3, let's stick to tef+

Evelyn, Alive, I am waiting for Eric checking this patch. Because this issue is urgent, I would like you take a look at the patch first. It's fine to give the final review once Eric confirms that this patch does solve the problem. Thanks!

Looks like things are in good shape here. Can this be landed and resolved?

I've re-tested based on Comment 7 pull request, it's good to go! Please just land it.

Thank you for doing the review and test! master: https://github.com/mozilla-b2g/gaia/commit/25253ebe685b3c112bb52b8f0af7c832eed9ea79 v1-train: https://github.com/mozilla-b2g/gaia/commit/23cec618ba1ad9f39da1fc5dfa2a4df2b2d5f933 v1.0.1: https://github.com/mozilla-b2g/gaia/commit/1a9dfa4599d3ac42d0e21a564d734a070a17f89a

Can you please provide steps to verify this fix - as we can perform blackbox testing from the UI?
