Bluetooth on SDM845

I'm not sure what ever caused this to work out of the box in the first place when first investigating mobile-nixos, but the issue with bluetooth was resolved by following https://wiki.postmarketos.org/wiki/Qualcomm_Snapdragon_845/850_(SDM845/SDM850)#Bluetooth, specifically running this script that they suggest:
#!/bin/sh SERIAL=$(grep -o "serialno.*" /proc/cmdline | cut -d" " -f1) BT_MAC=$(echo "$SERIAL-BT" | sha256sum | awk -v prefix=0200 '{printf("%s%010s\n", prefix, $1)}') BT_MAC=$(echo "$BT_MAC" | cut -c1-12 | sed 's/\(..\)/\1:/g' | sed '$s/:$//') btmgmt -i hci0 power off btmgmt -i hci0 public-addr "$BT_MAC"bluetooth needs a temporary valid random mac on boot, and in pmOS they use
bootmacto do this during boot I discovered after chatting with them in the sdm845-mainline matrix channel.

bluetooth needs a temporary valid random mac
The linked documentation doesn't seem to imply it is temporary. Additionally, this is not random, this is clearly using the serial number (as would be passed down by the command line) as a seed.
Was there anything from the discussion you had with the PostmarketOS people you can quote about randomness or temporary?

I've made a hacky module temporarily for my own use that works, looks like this
{ config, lib, pkgs, ... }:
let
cfg = config.mobile.quirks.qualcomm;
inherit (lib) mkIf mkOption types;
in
{
options.mobile = {
quirks.qualcomm.qca-bluetooth.enable = mkOption {
type = types.bool;
default = false;
description = ''
Enable this on a device which uses the hci_uart_qca driver and needs a
random mac address set in order to allow bluetooth functionality to work
correctly
'';
};
};
config = mkIf (cfg.qca-bluetooth.enable) {
systemd.services.qca-bluetooth = let
script = pkgs.writeShellScript "qca-bluetooth.sh" ''
set -x
trap 'sleep 1' DEBUG # Sleep 1 second before every command execution
export PATH="${lib.makeBinPath (with pkgs; [ bluez coreutils-full gawk unixtools.script ])}:$PATH"
SERIAL=$(grep -o "serialno.*" /proc/cmdline | cut -d" " -f1)
BT_MAC=$(echo "$SERIAL-BT" | sha256sum | awk -v prefix=0200 '{printf("%s%010s\n", prefix, $1)}')
BT_MAC=$(echo "$BT_MAC" | cut -c1-12 | sed 's/\(..\)/\1:/g' | sed '$s/:$//')
script -qc "btmgmt --timeout 3 -i hci0 power off"
script -qc "btmgmt --timeout 3 -i hci0 public-addr \"$BT_MAC\""
'';
in {
description = "Setup the bluetooth interface";
wantedBy = [ "multi-user.target" "bluetooth.service" ];
script = toString script;
serviceConfig = {
User = "root";
Type = "oneshot";
RemainAfterExit = true;
};
};
};
}Regarding what they said in the SDM845-Mainline room:
Dylan Van Assche: Bluetooth needs a valid MAC, we have bootmac for this to take
care of during boot.
system64: Yup
But that's a pmos specific thing
I wish the changes would be upstreamed and fixed in the driver itself
Dylan Van Assche: Yeah it is annoying, I once digged into the whole Bluetooth
kernel stack to understand why BNEP was failing, turns out the MAC address was
set but it was just invalid.
system64: Sooo this is a kernel bug
A proper one must be set and that should fix it?
Hoping someone can push something that creates a random addr literally any valid
random mac addr
Proper device specific one could be set in pmos via bootmac or if other distros
care then they can implement something like that But BT should work by default..
Not by having to run custom commands in userspace..
Dylan Van Assche: Yeah, but needs to be unique as well, or you get issues, hence
bootmac using machine-id or serial-id

@MatthewCroughan Thanks for your great deployment. and the bluetooth's speaker is working normally now. only default sound card tfa98xx still need to be checked further.

how do you guys even have wifi working on latest commit (oneplus 6, non T)?

fyi:nixos25.05 used kernel 6.4.0 fixed bluetooth issue.
