Bluetooth not working

[vansloneker]

On my Lenovo G700 laptop Bluutooth does not seem to work. It is showing in the panel, however does not find any devices. It is working perfectly under the other operating system on this computer. I do not see it listed under inxi -Fxz

Maybe it is a driver issue?

[JeremyB]

More likely to be a firmware issue, a decent tutorial at https://askubuntu.com/a/632348/300665

[vansloneker]

Thank you for your reply.

[JeremyB]

Post results for lsusb if you need more help with it

[vansloneker]

I dug into it but found it all very complicated.
I'll post lsusb asap, other issues demanded my attention priority.

My bluetooth audio was initially working fine under Mint 19, but some update seems to have broken it. Bluetooth scans and finds the speakers, having already been correctly paired to them. But when I try to connect it, it connects briefly and then immediately disconnects. Kern.log shows repeated error messages: 1522.001134] Bluetooth: hci0: last event is not cmd complete (0x0f). It has been doing this both before and after the Bluetooth update that showed up this morning on Update Manager.

I just made an edit to fix the problem command, supposed to be cp for copy not cd

[vansloneker]

Thanks again.
It works, but not 100%. A tested headphone works ok.
A keyboard connects, but the system does not respond to inputs from the connected BT keyboard.

[JeremyB]

I can't be sure on that problem as I have tested bluetooth with a compact Logitech keyboard and it works fine, it appears you might be using an Apple bluetooth keyboard

[vansloneker]

It's just an ordinary cheap BT keyboard from the cheap-store.
