1. connect unagi device to mac book pro via bluetooth
2. launch gallery app
3. from mac book, transfer photo of size 6 KB (see attached image) via bluetooth
4. on the unagi device, accept the transfer
5. View the gallery app for the newly added photo.

Expected: Image is added
Actual: Image is not added.

Small size media (music, photo, video) files < 25 KB (approx.) when received via Bluetooth doesn't trigger change notification inside Gecko.

As a result if the respective app (Music, Gallery, Video) is open in background, the file doesn't show in the app. Only closing and reopening respective app triggers scan, and shows the file.

Media files in bigger sizes successfully triggers change notification for music, video and photos and if the app is open in background, the file shows up in the app immediately.

I worked with Punam trying to reproduce this and everything works perfectly when transferring from my linux host.

I even sent Punam one of my development images (for unagi) and the problem (BluetoothOppManager::NotifyAboutFileChange wasn't called) only manifested on her Mac. When the same small file was sent from my linux machine, BluetoothOppManager::NotifyAboutFileChange was called.
I'm going to change this to general, since my gut tells me this is a gecko problem and not a gaia problem.

Just in case its relevant, adb shell cat /proc/version reports (for both my phone and Punam's phone):

Hi Punam, Dave,

This is a Gecko Bluetooth bug, I'll take it. Thanks for reporting this.

I can reproduce this issue on Mac Air. This is because Mac Air wraps the photo in one packet, and BluetoothOppManager does not send notification in this case.

Triage - partners will take this as leo+

Attached example seems to be a common image size that can be downloaded from the internet.
