Bluetooth not working rockpi 4

Hello

I am having Rockpi 4 B and C both the boards. On both the boards with Debian Images bluetooth is not working. There is not adapter for the BLE and not able to start the scan even power up also not working.

If I use the Ubuntu on the the boards it works well. For my further task I need Debian with working bluetooth.

I have tried all the possible ways but no luck.

Can you please help?
