Bluetooth dongle, Strange behavior

Post by zyssai »

Hi!

I have 2 Bluetooth dongles.
The left one from Hardkernel, the right one from Amazon (because HK is now discontinued, so I need to try other ones as i need to make same project for friends).

HK dongle works perfectly. Amazon dongle keeps disconnecting.

They have the same lsusb (first one in the list)

I'm using last LineageOS 18.1
Someone know what's the problem :?:

Both of them seemed to have the same chipset CSR8510 A10.
But, it is hard to know what's wrong.

BTW, is this meaning that you had to enable the Bluetooth connection menu in the Android Settings when it disconnected from time to time?

Not exactly.
I need this dongle for connection with my amplifier (not for the sound, but for setup filters, delay,.. with a dedicated app)

With HK dongle no problem, but with the other, connection is done, then few seconds later it disconnect.

I have no idea indeed. Sorry.

But, I'm very curious if it works fine for generic audio devices at least or not.

I will made some further tests but very strange. The real problem is that HK discontinued there dongles, so how to add Bluetooth functionality now?

Our Bluetooth dongle manufacturer closed their business last year and we had to discontinue it.
But, many users reported any BT dongles worked fine on Linux/Ubuntu platforms at least. Therefore, we didn't think it was not a serious issue.

I guess it is worth to replace the problematic dongle just in case.
