Well, yeah, qualcomm developers did a lot of the linux ath9k/ath3k support
:)

I've booted off Fedora 26 USB thumbdrive, to discover that everything
works (dualband WiFi, BT, devices can be discovered), so the hardware
is not faulty.

I've converted Linux' drivers/bluetooth/ath3k.c to libusb to obtain
rom_version and ref_clock of my card, so I know which firmware files
I need (just in case):

  # ./a.out
  get_state -> 1, state = 0xce
  get_version -> 20, rom_version = 0x1102, clock value = 40

I've then rebooted back into FreeBSD.  Apparently, this AR3012 hardware
if very fragile, it can be easily left in confused state and won't accept
further commands, "usbconfig reset" does not help.  To avoid this, it is
better run ./ath3kfw as root, after powercycling machine (to reset the
card).  This got me further:

After that, ``hccontrol inquiry'' stops working at all (says "operation
timed out"), dmesg shows this:

ng_hci_process_command_timeout: ubt0hci - unable to complete HCI command
OGF=0x1, OCF=0x1. Timeout

./danfe

P.S.  Fedora is amazing (just as Ubuntu) on this laptop: everything works,
WMI multimedia keys, LCD brightness control, mic/speaker mute buttons, WiFi
and Bluetooth.  Under FreeBSD, only WiFi works from this list. :-(

Re: TDMA Wireless status?

[Stephen Patrick]

Thanks Adrian,

We are interested in "long range outdoor" (10-20km) with high gain antennas.
Do you know "Mikrotik Nstreme/NV2" and "Ubiquity Airmax" ?
Those have framing/polling done in software - wrapped around the wireless
driver.
Is there equivalent developed in FreeBSD?

Best regards

Stephen
