1. Pairing a Nexus 4 and a Buri.
2. Send image from Nexus4 to Buri.
3. <ISSUE >Nexus 4 shows 'The transfer has started' in notification, no file actually sent.

4. Continue to send image from Buri to Nexus4 -> okay
5. Continue to send image from Nexus4 to Buri-> okay
6. Switch off Bluetooth on both phones.
7. -> back to step 2 & 3.

It works on my Nexus 4 and Unagi (sorry but I don't have Buri at hand). Which Buri build were you using? Could you attach Buri's hcidump log? Thanks.

I waited from "The transfer has started' to 'File could not be sent' (UI on Nexus 4 notification).

The HCIDUMP has nothing on BURI

xxxx@xxxxx:~/Desktop$ adb shell hcidump dev0 --hex
HCI sniffer - Bluetooth packet analyzer ver 2.0
device: hci0 snap_len: 1504 filter: 0xffffffff

That implies your nexus 4 has never sent any packets to Buri. The same issue was reported once and I don't think we're able to solve it from Gecko side in the near future. When inquiry is in process, any outbound connection seems to be very easy to fail. It's more about the capability of stack.

Shouldn't block any other bugs since BT transfer still works most of the time.

Close as WFM since we don't see the same symptom for about 9 months.
