[SOLVED] LM 20, Bluetooth not detecting any device

[ppojol]

Hello all. I am really new to Linux and have very recently replaced my Windows OS with Linux Mint 20 on my HP Stream 11. Everything works fine and I am very pleased, except that the Bluetooth on my laptop detects NO devices. I have searched for posts on the same problem and have tried different solutions but none seems to work. Based on my beginner's reading of the posts, I may lack firmware, but I do not know how or where to obtain it.

Following what I have seen in other posts, here is information about my system that may be helpful:

If it is the same version the BCM43142 then the same solution!

Thank you for your tip, asinoro.
I also saw the same post during my previous search,
and I tried the commands again, just in case.
But still no devices found by my Bluetooth.

Hoping to find a solution....

Different file in that other thread. Try this instead:

Code: Select all

wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM43142A0-0a5c-216d.hcd
sudo cp BCM43142A0-0a5c-216d.hcd /lib/firmware/brcm

Shut down when done. Wait 2 minutes then power up into Mint.

Do this and reboot

Yeah, do that!

Thank you very much, JeremyB and MrEen!
Finally my bluetooth works!

[MrEen]

That's great ppojol!

I'm slowly learning how JeremyB helps users solve these issues. By the time I get there though, there'll be something that has long since replaced WiFi and Bluetooth I imagine.

[ppojol]

Still, my thanks to you MrEen for attending to my problem.

[MrEen]

Glad we could help.

[hglee]

Note there are two close releases of Broadcom BCM43142 devices involved: The earlier report is of the BCM43142 chip ID 0a5c:21d7, while this latter one is of a BCM43142A0 chip ID 0a5c:216d.

The two successful downloads are of firmware BCM43142A0-0a5c-21d7.hcd, which appears (misleadingly?) labeled as being for 0a5c-21d7 rather than (or including both?) the 0a5c:216d, while the 404 failed downloads are of firmware fw-0a5c_21d7.hcd only, which might be discontinued.

If need be, for testing purposes, here's a download link for the 0a5c-21d7 firmware.

Thank you so much! This worked beautifully for me even today (March 26, 2022).

I have bluetooth device issues too. Can this commends be applied for every computer or specific to a certain type of computer?
