[Bug 1692448] Re: Bluetooth speaker fails to reconnect when turned on (but it tries)

[Daniel van Vugt]

I finally tested:

https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/src/service.c?id=2e2edc36a91d6a8f2c65d793273df28a166d6bed

on xenial. But it did not improve the situation.

** Description changed:

  Bluetooth speaker fails to reconnect when turned on. Watching the
  Bluetooth icon in the Unity panel I can see it is trying (B icon briefly
  gets the expected padlock and then loses it). The speaker doesn't
  reconnect then unless initiated by the laptop (set Connection = ON in
  the panel).
- 
- Sounds kind of like this (which is fixed in newer releases than xenial, but not in xenial):

  Note this bug is only about the Bluetooth connection, and not about
  audio problems (of which there are a few).
