Doc for Qualcomm AR3001 HCI

[Frank Zhao <frank.zhao.main@gmail.com>]

I am doing some hacking on a PlayStation 4's DualShock 4 controller,
inside is a Qualcomm Atheros AR3002 connected to a microcontroller
using UART HCI. I have a logic analyzer connected to the UART signals
and I have captured a lot of data. But a lot of the HCI commands have
OGF of 0xFC which means that the commands are "vendor defined", and
thus they are not in the HCI functional specifications documentation.

I can't find any helpful technical documentation at all from
Qualcomm's website and they probably won't help some hobbyist anyways.
I've searched Google and found your website. You guys have written a
driver for this chip already, so you must have some documentation on
Qualcomm's own HCI commands. Can you please share this documentation
with me?

Thank you

to try linux-bluetooth instead
