Bluetooth 5

[henkiewie]

Hi, To my surprise I got WiFi working on my ryzentosh with the latest airportitwlm.kext with my intel x200 chipset on Catalina 10.15.7 on opencore 0.6.4. The heliport app isn't working (doesn't seem to find any BT, but I'm just using the standard WiFi options. I have to reconnect by hand after reboot (adding my ssid and password in the info.plist did not seem to work). Bluetooth was already working before using the new kext, but it seems to be stuck on an older or unkonown version. I'm looking for a way to force the version to Bluetooth 5 mainly because of the delay when using audio. But I have no idea how. I have a headphone Sony that supports bt5 and aptx but changing the parameters doesn't work it's SBC only for now. I can channge this when I connect the headphone to my android phone it's a hassle, but just to let you know the headphone supports this. Also turning on aac does nothing. When I look for the lmp version it states unknown 0xa. I've been using bluetooth explorer and the command line to try make it happen, but it doesn't. I tried the bluetoothfirmware.kext, but it seems to break my bluetooth.

macOS didn't support bt5.1 and 5.2, so it shows as unknown. also, itlwm just a wifi related kext, not bluetooth, please use intelbluetoothfirmware.

Just for the record. For the CODEC It was the headphone afterall. Collected some different headphones for testing AAC en AptX are working, but not for WH-1000XM3 in my case it still on SBC. Still looking for a way to force 0xa to 0x9. Firmware kext is loaded but boot log has no entries.
