How to disable onboard bluetooth

Help & Support Hardware
1

Hi,

I would like to ask you for your help. How can I disable onboard bluetooth and use usb bt dongle instead? I´m running on Khadas Vim2 Max, CoreELEC 9.2.

The problem is, that onboard bluetooth has very limited range, so I would like to use USB dongle.

Thank you very much
M.

Do you need to disable it?

Try plugging in the dongle, just choose the external one

3

Where to choose it, please?

Coreelec under blue tooth devices, when you turn on the device, you will see them.

I can choose devices, but not usb dongle…

6

sorry I don’t know.

From what I understand,you need to blacklist the device that you don’t want to use.

I don’t know if This may be of help but searching for blacklist might yield more helpful results.

I´m trying to do that, but don´t know, what to put on blacklist…

btsdio should be the onboard bluetooth.

Unfortunatelly it´s not. When I go to BT settings in Coreelec, it again finds some devices…

According to this thread the location of the blacklist.conf is different,

I’m not sure exactly which option to blacklist as there is bluetooth, btsdio, bnep and hci_uart but you could blacklist each one in turn and then plug in your dongle to discover which combination works.

Many thanks to all of you. It works with hci_uart…
