Lenovo Z710, 16.04 LTS and Bluetooth (or lack thereof)

JBL Bluetooth speaker cannot be found by my laptop. All the Bluetooth apps/drivers seem to be installed correctly (one error that I noticed, below). Cell phone has Bluetooth turned off as it has a current pairing relationship with the speaker. Speaker was power cycled as was my laptop, yet the laptop cannot find the speaker. Output from " lspci -nnk | grep -iA2 net; lsusb; hciconfig -a; dmesg | egrep -i 'blue|firm' " is as follows:

Might the boldfaced section be the problem? I honestly don't know what to do from here. Thanks!

Code:

---

wget https://www.dropbox.com/s/f503f6r686riiow/fw-105b_e065.hcd
sudo cp fw-105b_e065.hcd /lib/firmware/brcm/BCM.hcd
sudo modprobe -r btusb
sudo modprobe btusb

Then it should work

Thank you! That got me part of the way home in that I now find the "JBL Charge 2" and can add it. It appears to pair OK, but when I go to "Connect" I get "Device added successfully, but failed to connect" and I get this whether I try "Headset", "Audio Sink" (?) or "Handsfree".

In this thread here - https://ubuntuforums.org/showthread....ght=jbl+charge - there is mention of being prompted for the PIN code, which did happen when pairing with my cell, but I have not been prompted for any PIN code thus far.

Is there a conf file somewhere that I can enter the PIN code or something like that?

Thanks!

I have never had to enter a PIN for a headset, post results for

Code:

---

pactl list short | grep blue

---

By the way, I managed to locate an error code that may help:

Code:

---

Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available

There are no results (hit "Enter" and it just drops to a new line; no response from the system).

Got it! Google'd the error code about "Protocol not available" and found this post: https://zach-adams.com/2014/07/bluet...-setup-failed/

Didn't work after the first step, but now is working fine after the second. Thank you!

OK, partially solved. The speaker has been found, paired, and connected ... but no sound comes out. Not as a headset nor with the high fidelity option. So, any ideas? =)

Thanks again!

See https://askubuntu.com/a/837732/300665 and see if it helps

OK, read through the link you gave me and the page it linked to as well. That looks ... awesomely confusing. What, exactly, do I do with that script? Sorry, but I do OK up to a point and digging into scripts is one of those things I've always wanted to understand but, as yet, I do not. Do I download the ZIP and ...? Unpack it ... where? And then what? Thanks again!
