Ben will take a first look. Thanks.

Device doesn't receive initial 4-byte socket info message so closes the outbound socket. Nexus 7 (4.4.2) and HTC One (4.3) cannot send file to mac either. Will check hcidump for more information.

Dietrich, please turn on bluetooth sharing on your mac as following and try again. The problem is gone after I turn it on. Let me know if it works for you as well. https://wiki.mozilla.org/B2G/Bluetooth#FAQ 5. Why can't I send a file to or receive a file from my Mac? If you would like to share files to Mac, the file-transfer function should be enabled beforehand. 1. Click the Bluetooth icon at the top-right corner of the screen 2. Select "Open Bluetooth Preferences" from the drop down menu, then click the "Sharing Setup..." button at the bottom right of the dialog that opens 3. Make sure the "Bluetooth Sharing" checkbox is enabled.

We have tested on MacOS X 10.8.2, based on Comment 3.

Yes, this was the problem. Apparently I will file this bug each time I use a new laptop! My apologies. On the Mac, because it's disabled, there's no indication that something has gone wrong. On our end, we might be able to get the user to a solution more quickly by giving a better message. If can we detect that Bluetooth on the paired device is *enabled* but file cannot be sent, is there something in the protocol that says "feature not supported" or "feature not enabled" so that we can give a better message to the user?

Gecko is unaware of "feature not supported" error since feature support negotiation is handled by bluetooth backend (bluedroid). Gecko only gets error to read socket data and then disconnects. ni? UX Neo to comment on better error message wording.
