Re: Please help with Bluetooth

Hello Jeremy,

Got back at trying again to make my bluetooth work; now I am using mint 18,3 Xfce, and have downloaded the correct firmware of broadcome... I as trying to figure out the steps again to make it work but it seems there is something missing?

Here, "Open this file by Archive Manager and find there bcbtums-win8x86-brcm.inf file. Name of the file may differ in some drivers. It can be bcbtums.inf located at Win32 or Win64 directory. It does not matter 32 or 64 bit to download.
Search this file for VID_0A5C&PID_21D7. These numbers are from your lsusb output

0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0.

Comment: Some devices are not recognized as Broadcom BT in lsusb. If you are unsure which one is your BT device, run usb-devices command, it will give more detailed information. There you can find product and vendor IDs.

You will see some line ending with RAMUSB21D7

Search this file for RAMUSB21D7." I do not know where to find the RAMUS information, also here is the information for terminal:

Code: Select all

lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0a5c:216c Broadcom Corp. BCM43142A0 Bluetooth Device
Bus 001 Device 004: ID 1a40:0101 Terminus Technology Inc. Hub
Bus 001 Device 003: ID 04f2:b40e Chicony Electronics Co., Ltd HP Truevision HD camera
Bus 001 Device 002: ID 248a:8367  
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

That's great! It would be helpful if you could describe the steps you took to get it working, & also add [SOLVED] to the title of your first post in this thread. :D

There seem to be a lot of people having problems getting Bluetooth to work properly and those Broadcom chipsets aren't exactly the best for Linux systems. I simply swap the cards for Atheros ones, these seem to work flawlessly on all versions of Mint I've tested. Good that you have yours working now.

The process is explained @http://askubuntu.com/a/632348/300665 for another broadcom device but it usually the same, search the inf file for the last 4 digits of your USB ID until you find the corresponding RAMUSB header and below it will be the name of the hex file you need to convert to BCM.hcd in most cases and move to /lib/firmware/brcm/

I have a BCM4313 broadcom wifi/bt that works without BT firmware and also doesn't need the proprietary Broadcom module. You don't even have to download hex2hcd as it is part of one of the bluez packages

Yes, I took step by stel that thread you described, the only problem is that I did not find anything about RAMUSB216C so I had to google it untill I found a page where I could download the Broadcom file that was missing, and it also said what BCM to use; in my case

[RAMUSB216C.CopyList]
bcbtums.sys
btwampfl.sys
BCM43142A0_001.001.011.0311.0328.hex

Then followed the steps and it did not work until I renamed the file to BCM.hcd, which you explained in other forum and it did work finally with Blueberry, I did not even have to install blueman.

Thanks, by the way I do not know how to change the subject to Solved so I would appreciate it if you can explain it.

Go to your original post in the thread and click on the pencil(edit) icon and add solved to the subject. I know it can be a pain getting Broadcom bluetooth to work, but their firmware license prevents distribution

Hello All,

One question... ever since I solved the problem with my bluetooth I noticed that my wifi reception is not as good as it was before; I have to be attached to the wifi antena so my computer is conected to the wifi. Do you think this have to be to the solving situation I did for my bluetooth to work?

Thanks, RD

I don't think there is a fix for the bluetooth coexistence as there aren't any parameters to be changed in the wifi module
