Love this! I’ve spent ages with a naff (and it was expensive) A2DP dongle plugged into a 3.5mm in order to output to BT speaker.
So things I’ve noticed, I’m sure most of them are knowns.
I can stream in from one bluetooth source and out to another, so bandwidth available for 2 paired devices both pushing stereo audio.
Once the incoming bluetooth sink is latched to an output it can’t be software swapped, ie if set to output to BT speaker, switching back to HDMI manually causes the audio to drop until you break the incoming link and reconnect. However, if you switch the BT speaker off it will fallback to HDMI audio, even though it’s not set to it.
Once the BT speaker has been connected it will disconnect and reconnect happily when switched on and off. The settings will switch HDMI to BT and back fine, and disconnecting/reconnecting speaker fails over and relinks fine if you’ve left the setting on ALSA. Both the incoming phone and the outgoing speaker needed a forced connect after boot. For the speaker this was by “re-connecting” in “My OSMC-Network”, for the phone I was able to trigger the connect by turning off and back on the “Throw” feature.
The Bluetooth Adapter is Cambridge Silicon Radio chipset. http://www.amazon.co.uk/gp/product/B00KNPTHS8
The speaker is Bose Soundlink III, phone input is Sony Z3C.
Happy to answered/try more if required.
Please could this add-on package remain available if the main features don’t get integrated into OSMC, the A2DP out to speaker is something I’ve needed for ages.
