The end result is that we do have a working device, using the firmware files that are found in the linux-firmware git repository already. Bluetooth: hci0: setting up wcn6855 Bluetooth: hci0: Frame reassembly failed (-84) Bluetooth: hci0: QCA Product ID :0x00000013 Bluetooth: hci0: QCA SOC Version :0x400c0210 Bluetooth: hci0: QCA ROM Version :0x00000201 Bluetooth: hci0: QCA Patch Version:0x000038e6 Bluetooth: hci0: QCA controller version 0x02100201 Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv Bluetooth: hci0: QCA Downloading qca/hpnv21.bin Bluetooth: hci0: QCA setup on UART is completed There are a few things that I am not sure why they happen, and don't have the knowledge level to figure out why they happen or debugging it. I do not know why the Frame assembly failed, and modprobe -r hci_uart and then modprobe hci_uart does not always show the same Frame assembly failed. The BD Address also seems to be incorrect, and I'm not sure what is going on there either. Testing was done by connecting a Razer Orochi bluetooth mouse, and using it, as well as connecting to and using an H2GO bluetooth speaker and playing audio out via canberra-gtk-play as well as a couple of YouTube videos in a browser. Additionally, a huddle was done in Slack on Chromium with a pair of Gen1 Apple AirPods as well as a hangout in Discord on Firefox ESR. steev@wintermute:~$ hciconfig -a hci0: Type: Primary Bus: UART BD Address: 00:00:00:00:5A:AD ACL MTU: 1024:8 SCO MTU: 240:4 UP RUNNING PSCAN RX bytes:1492 acl:0 sco:0 events:126 errors:0 TX bytes:128743 acl:0 sco:0 commands:597 errors:0 Features: 0xff 0xfe 0x8f 0xfe 0xd8 0x3f 0x5b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF Link mode: PERIPHERAL ACCEPT Name: 'wintermute' Class: 0x0c010c Service Classes: Rendering, Capturing Device Class: Computer, Laptop HCI Version: (0xc) Revision: 0x0 LMP Version: (0xc) Subversion: 0x46f7 Manufacturer: Qualcomm (29) steev@wintermute:~$ dmesg | grep Razer [ 3089.235440] input: Razer Orochi as /devices/virtual/misc/uhid/0005:1532:0056.0003/input/input11 [ 3089.238580] hid-generic 0005:1532:0056.0003: input,hidraw2: BLUETOOTH HID v0.01 Mouse [Razer Orochi] on 00:00:00:00:5a:ad steev@wintermute:~$ dmesg | grep H2GO [ 3140.959947] input: H2GO Speaker (AVRCP) as /devices/virtual/input/input12 steev@wintermute:~$ dmesg | grep AirPod [ 853.742619] input: Steev’s AirPods (AVRCP) as /devices/virtual/input/input14 v7 Addresses commit message review nits by Paul, as well as dts changes requested by Johan.
