Bluetooth not working

Hello , I have a bluetooth problem
I have followed the bluetooth setup on https://wiki.radxa.com/RockpiS/Debian
It is a clean debian install.
I get the following output .
there is no output for hciconfig

If anyone has an idea to what the problem might be it will be very appreciated.

What are the hardware version and system image of your ROCK Pi S?

i am using the latest rock pi s with 8gb of flash
and the latest debian image from the radxa website

i tried getting the version

apt install lsb-release

I think you can try these steps.

Firstly, make sure there is a wifi chip on ROCK Pi S.

‘ifconfig’ would show p2p0 and wlan0 interfaces.

Secondly, manually setup bt.

echo 0 > /sys/class/rfkill/rfkill0/state
echo 1 > /sys/class/rfkill/rfkill0/state
version=`uname -r`
insmod /lib/modules/${version}/kernel/drivers/bluetooth/hci_uart.ko
