I've had a B2 for some time now, and whilst every now again it can be a bit twitchy so far I've been quite pleased with the experience. However, I recently picked up an Echo Show 8 (and a Bluetooth dongle for the B2) and things have, to use the words of the Immortal Burns,
gan aglae.
As I understand it, if I pair the B2 and the Echo, I should then be able to use the B2 as a Bluetooth speaker for the Echo. (I have it connected by optical to my amp+speakers.) However, the devices seem to think I want to do the exact opposite.
Using the Bluetooth button in the GUI I've got the B2 to see the Echo and vice versa. However, if I connect, the only thing the Echo will do is try to receive an input from the B2, which causes it to display a large Bluetooth icon on the display with the message 'not supported'. At one point, the Echo even somehow made the B2 start playing a track from my B2's library, whilst still continuing to play a completely different track through its own speakers, which sounded exactly as good as you'd expect it not to.
Am I critically misunderstanding how the two should work together, or is there some step I'm missing?
