Activating Bluetooth on intel AX200,AX201,AX210 modules

HI

I  have  a   3 years  Old  FUjitsu Celsius H7510   with I7-10885H  CPU  
and   AX201
instructions in the Handbook talks about inserting a Bluetooth dongle in 
a USB port.
This is obviously not the case here as the AX201 M.2. card includes the 
Bluetooth circuitry and the Bluetooth antenna is pre-installed in the 
laptop.

   As Bjoern.Zeeb    has  done  an  enormous  job  on  the  AX200 
IWLWIFI  side,   this  bluetooth  part  of the  same circut-board  may 
interact  with  the  WIFI    part  .......


this is what I can discover ,

# dmesg -a | grep AX201

iwlwifi0: Detected Intel(R) Wi-Fi 6 AX201 160MHz

# dmesg -a | grep ubt0

ubt0 on uhub1
ubt0: <vendor 0x8087 product 0x0026, class 224/1, rev 2.01/0.02, addr 5> 
on usbus0

In /usr/src/sys/dev/usb/usbdevs

# iwmbtfw -I -d ugen0.6

# ps -ax | grep hcsec

# ps -ax | grep sdpd

Looks like the Hardware should work but :

# service bluetooth start ubt0
/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0


    PLS   advise   how  to  further  diagnose  the  case,

   regards
