PI(3) recent bluetooth issues?

Post by lost »

Hello,

If you experience issues recently using bluetooth on PI3, this may be because patched firmware is not loaded anymore at boot due to a path mismatch, see hereunder:

In my case, I use BT just for phones lookup/presence detection. Was 100% reliable since august updates (I only installed last week).
Looks now solved by a symbolic link:

Regards

You're right:

Code: Select all

sudo ln -s  /lib/firmware/ /etc/firmware
Firmwares have always been located in /bin/firmware but current BT seeks them from unexisting /etc/firmware... Killing hci & re-launching /usr/bin/btuart script manually makes hciattach complaint clear.
