Bluetooth BCM43xx error with hassio. 0.67.0

Hello
I am running Bluetooth BCM43xx device tracker. It was working ok with the previous version 0.66.x. I updated to 0.67 and the behavior become sporadic.

Two changes:
(1) in known devices: the devices MAC address changed. From BT_14:56:8E:45:D4:49 to BT__14:56:8E:45:D4:49. Note that I got “double underscore”. Before, with previous HASSIO release the name had only one underscore

(2) i get a lot of errors in the home-assistant.log file as below

Anybody else had the same issue?

Error:

Yes I had the same problem, the double underscore entries in knowndevices.yaml can be deleted. I read somewhere that it’s a bug that will be fixed in the next release.

Found your tread, I also have starting having issues with the Bluetooth BCM43xx, in will not start…

starting version 3.2.4
bcm43xx_init
Initialization timed out.

Is this also a bug or is something wrong with my Pi3?

its a bug tht will be fixed in the next release
