Hi Lars,
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 .......
Not my domain of expertise but:
(a) which ersion of FreeBSD are you on?
(b) Check if you have an 0x0026 entry in
/usr/src/sys/netgraph/bluetooth/drivers/ubt/ng_ubt_intel.c: {
USB_VPI(USB_VENDOR_INTEL2, 0x0026, UBT_INTEL_DEVICE_8260) },
(c) did you install firmware? There is an iwmbt-firmware package. Looks like
you have.
(d) last time I tried I with an AX210 I had to try to start it 1..4
times until eventually it worked.
Reading below I think you are in the (d) category.
Here's notes I left someone else for that trial:
------------------------------------------------------------------------
I installed the iwmbt-firmware package manually and then manually loaded
it, twice; the 2nd time with -DI and then started
/etc/rc.d/bluetooth start ubt0
one more time and then it was there..

Looks like the Hardware should work but :
# service bluetooth start ubt0

PLS advise how to further diagnose the case,
