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 Frank Zhao PS: I originally wrote this email to linux-wireless but they told me to try linux-bluetooth instead
