Yet another bluetooth thread

both bluetooth and wifi…

Basically “why not”, considering that in both cases external dongles are required, and who knows what do you have on your shelf to plug it. I do not see a problem in having both options.

To my understanding, wifi support had been added later as an experimental feature, so having both has at least historical reasons, as a part of continuous development.

I hope that in the future wifi could be used as a hotspot for accessing webui, and updated bluez stack would lead to midi-over-bluetooth support without CME WIDI dongles. If it would happen one day, it’s how it makes a perfect sense to have both even working in the same time.

Tried Hama bluetooth 5 dongle with Dwarf, seems to have Realtek chip in it. It shows only “starting” forever when I go to bluetooth menu and doesn’t go past that. Any tips how to get it to work, or should I just get different dongle?

I have same problme
have any idea for this?
My BT dongle is tp-link UB500

I have the same dongle, and it works for me.
Anyway, the connection is very slow, so i’m not using it anymore.

These model names might mean nothing in a world of dlinks/tplinks and other vendors like that.

I know nothing about this model, but in general - tplink can sell completely different hardware under the same name, one would have Realtek chip, another Broadcom chip, and they would have different drivers, compatibility, etc.

Naming difference would be only in some obscure revision number which seller never tells you.

At least this applies to wifi hardware, and I would expect same from Bluetooth as well.

Same model dongle TP-Link ub500. Same problem of stuck “starting…”. When I am able I will see what chip it is using and see if I can get it going. I don’t really feel like purchasing endless Bluetooth dongles just to find one that works.

t seems that I have a UB500 v2 which is using Realtek Bluetooth 8761B chipset. I assume I need to SSH in and create a /data/firmware/rtl_bt directory and copy both the firmware and config bin files in?

AND
https://kernel.googlesource.com/pub/scm/linux/kernel/git/firmware/linux-firmware/+/refs/heads/main/rtl_bt/rtl8761b_config.bin

Is that correct?

Hi, I think I might have a similar problem. Did you try that and did it work? Thanks!

Stranger things. I SSH in and plugged in dongle. Dmesg said both fw and config bin files loaded (they were already found on the device, I didn’t have to copy them in). Bluetooth was then discoverable on the mod dwarf and I could connect. The next time I tried, powering the MOD Dwarf with the dongle in, I had the same issue again and could not connect. I have found that it works if I wait until the Dwarf is booted before plugging the dongle. Perhaps the Wiki needs reviewing about this.

Haha… plugging in after boot seemed to work for me too. Thank you!
