5,076
You are missing firmware for the bluetooth.
cd /lib/firmware/brcm
sudo wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-13d3-3404.hcd
sudo modprobe -r btusb
sudo modprobe btusb
See if it works

Why does Blutooth not connect?
The Bluetooth unit can find, but not connect to other devices on Debian Testing (9.0 Stretch). Bluetooth works well with a different Operating System. BIOS settings permit wireless.
The following packages were installed:
- bluez-firmware
- broadcom-sta-common
- broadcom-sta-dkms
- broadcom-sta-source
- firmware-brcm80211
- firmware-misc-nonfree

Vineet Basantani about 7 yearsThanks very much. There was an improvement. For a few seconds, the button changed to disconnect. But now it is back to connect again. 1) The other files in that folder are .bin, not .hcd. 2) Maybe the speaker actually is connected, but the interface says it isn't. How could one check using the CLI?

Jeremy31 about 7 yearsCheck
pactl list short | grep blue
to see if module-bluetooth-discover is loaded, if notpactl load-module module-bluetooth-discover
Then see if reconnecting works -
Vineet Basantani about 7 yearsThanks again @Jeremy31 The first command run as root returned no message. The second command had the following error message: Failure: Module initialization failed

Vineet Basantani about 7 yearsAs pulseaudio-module-bluetooth was absent, I installed it, but there seems to be no improvement. There is no file /usr/bin/start-pulseaudio-x11. Maybe a reboot or something is required.
