# NAME

`aubtfwl` — Atheros AR3011/AR3012 Firmware Loader

# SYNOPSIS

`aubtfwl* at uhub?`

# DESCRIPTION

The `aubtfwl` driver manages automatic loading of firmware on the Atheros AR3011 and AR3012 Bluetooth chipsets. The firmware files should be obtained and placed in a ubt/ directory in the search path of the firmload(9) kernel subsystem. Upon attachment, the `aubtfwl` driver will load the necessary firmware files and the device will detach and reattach as a generic Bluetooth device using the ubt(4) driver.

For AR3011 chipsets, you will need the ath3k-1.fw firmware file in ubt/, and for AR3012 chipsets, the files ar3k/AthrBT_*.dfu and ar3k/ramps_*.dfu in ubt/ar3k/.

The firmware files can be obtained from the Linux firmware git repository at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git.
