Cambridge Silicon Radio, Ltd Bluetooth Dongle — Not Connecting

Cambridge Silicon Radio, Ltd Bluetooth Dongle — Not Connecting

Post by Mihail-Cosmin » Sun Feb 02, 2020 8:08 am

I have a Bluetooth Dongle: Cambridge Silicon Radio, Ltd Bluetooth Dongle, that shows on my system ( Linux Mint 19.3), but doesn’t work to connect in any way.

When scanning with my phone I can see this device «00:1A:7D:DA:71:10» but when I try to pair, it doesn’t connect.
Also from my laptop if I use blueman to search for devices I get this error:

Does anyone have any idea how I can fix this?
One more thing, the reason I bought this dongle was because my laptop integrated bluetooth adapter also wasn’t working.
Maybe these 2 issues are connected?
I would be happy if either of the 2 Bluetooth adapters could work.

Some additional info on my system:

I have the same problem as you. My POST

You can try to load an older kernel. I could only make it pair and connect with devices on kernel 4.15.0-20-generic.

I might be wrong, but I would think that would be for Bluetooth adapters that use Broadcom chips. The issue in this thread is a Cambridge Silicon Radio (CSR) bluetooth chip.

I have a Cambridge Silicon Radio bluetooth adapter.

Mine works. I find it a lot better than the Broadcom-based bluetooth adapters. From my experience, CSR chips have issues with the initial connection, but once the connection occurs, they work perfectly. Broadcom-based bluetooth adapters connect easily, but have terrible range, lag and disconnect all the time. So I do prefer the CSR chips

But the last week or so, I’ve noticed that I’m having a lot more trouble with the initial connection on my Bluetooth headphones. Not sure if an update caused it, or if it is something else.

You’re both correct and wrong at the same time. In the first post the OP asks about getting either working. As we had a dmesg error showing for the built-in BT, I thought to offer that idea to see if we could get that working.

I also have and use the CSR dongle where only the initial setup was «troublesome» but fixed eventually that I described here. That was using my 18.3 Xfce install. I haven’t installed 19.3 yet, so don’t know if I’ll experience new issues there.

Interesting. I’ll give it a shot too.

But, for me the CSR module doesn’t only have problems with headphones. I notice it with the Xbox controller bluetooth connection. Same issues — Broadcom connects right away, but the controller disconnects constantly. CSR has problems connecting the controller. The solution that usually works is to pass the ‘connect’ command to ‘bluetoothctl’.

[SOLVED] How to Make a USB Bluetooth Dongle Work with Linux Mint 18.3 Sylvia (Cinnamon 3.6.6)?

[SOLVED] How to Make a USB Bluetooth Dongle Work with Linux Mint 18.3 Sylvia (Cinnamon 3.6.6)?

Post by mintyfreshuser » Sat Jan 06, 2018 11:28 pm

I’m using Linux 18.3 Sylvia with Cinnamon 3.6.6 desktop environment and I’m having a problem getting Bluetooth to work with my computer.

I’m using a USB Bluetooth dongle. I know that the dongle works because I used it on another operating system and it worked then.

The Bluetooth devices that I’ve tried paring don’t show up at all when I scan for them using the Bluetooth software that I’ve tried.

So far I’ve tried using the Linux Bluetooth programs called «Blueman» and «Blueberry», but neither of them have worked.

With that said, what can I do to make this USB dongle work with this version of Linux Mint?

Can you provide more details? for example what is the manufacturer of the BT dongle? Have you checked the syslog to see what kernel messages are coming up for bluetooth? More than likely the BT dongle uses broadcom chip inside and you will need to get a proprietary firmware for it to work.

I had similar challenges in my thread here that might help you

Hi. Thank you for replying.

I’m not sure who manufactured the Bluetooth dongle, but it looks like this:
https://www.ebay.com/itm/Bluetooth-Mini . SwWKtUrIHZ.

I don’t know how to check the syslog to see what kernel messages come up for Bluetooth. What do you type in the terminal to do that?

Right now I’m using the graphical Bluetooth manager called Blueman if that helps.

I’ve gotten these messages: «Device added successfully, but failed to connect» and «Connection Failed: blueman.bluez.errors.DBusFailedError: Host is down».

I just read your post and the good replies to it. Here are my thoughts on this as well.

It would help to know more about your system setup. If you run » inxi -Fxzd » from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.

I have what appears to be the same type of USB Bluetooth Adapter (from Amazon.com) and when I boot up Cinnamon 18.3 it works just fine using «blueberry» Bluetooth. Works well in Linux Mint 18.2 KDE too. After I put the Bluetooth device I wanted in pairing mode, It took at least a minute on my older computer before it recognized it, but then it worked perfectly. It was quickly recognized after the first pairing.

Exactly what Bluetooth devices are you trying to connect with?

I connected a Bluetooth headset Motorola HT820 (and a Bluetooth stereo clock radio that is recognized as a headset), then I had to tell the sound system to use it which can be done from the system tray volume control (right-click, or regular click to Sound Settings) or from the Menu -> System Settings ->Sound.

On either Bluetooth device, it shows two sound options:
High Fidelity Playback A2DP Sink — volume controlled by computer and Bluetooth device, better sound, but no microphone option just speakers.
or
Headset Head Unit HSP/HFP (default) — volume controlled by Bluetooth device only and has microphone options, sound was not as good on mine.

FYI: I do not recommend using «passive» USB hubs which do not have their own power supply because they do not work well in Linux, or worse they work intermittently.

Hope this helps .
