Hi Eric,

I make sure that Gaia does not received onDeviceFound() callback while a user click "Search for devices" button in BT headset connected state.

Gaia register callback function "defaultAdapter.ondevicefound" in 
https://github.com/mozilla-b2g/gaia/blob/v1.3t/apps/settings/js/bluetooth.js#L60

And the onDeviceFound() function be called in
https://github.com/mozilla-b2g/gaia/blob/v1.3t/apps/settings/js/bluetooth.js#L568

I would like to suggest Gecko::Bluetooth for investigation the situation.

Ian, which BT headset is this?
Also which build are you on?

Naoki,

The headset is JABRA TALK. And I will try it again with latest build version with different headset module since my build updated. I'm requesting other BT headset module from partner.

I can reproduce. This is an issue because of custom bt-stack or the capability of bt firmware.

When there is a bt profile-level connection, I try to start inquiry but got an InquiryComplete event replied immediately, which indicates that the inquiry process has completed.

< HCI Command: Inquiry (0x01|0x0001) plen 5
    lap 0x9e8b33 len 8 num 0
> HCI Event: Command Status (0x0f) plen 4
    Inquiry (0x01|0x0001) status 0x00 ncmd 1
> HCI Event: Inquiry Complete (0x01) plen 1
    status 0x00

Steven, could you assist with passing this issue to partner to confirm what I observed?

Ian, I don't think this is an IOT issue. So I think you don't need find another device to do further test. Thanks for reporting.
