bluetooth audio performance

[sbaier1]

i'm using the DW1560 as well in conjunction with BrcmPatchRAM3 and BrcmBluetoothInjector (2.5.0) on Catalina.

It's working, but when using my aptX headphones (ath m50xbt) it appears that the card has issues with multiplexing the wifi and bluetooth connections. When streaming something and playing audio at the same time, the audio cuts out quite often, sometimes even losing connection entirely.
The context menu reports a signal of about -73dBm which seems fairly low considering i'm sitting right in front of the laptop with the headphones on.

Has anyone else experienced this? I've tried using Bluetooth Explorer to change the default codec but it doesn't make a difference.

edit: It appears that using a 5GHz wifi instead mitigates the issue somewhat, the RSSI is now at about -50dBm

Had the same problem and the same resolution.

For others:
aptx bluetooth audio + 5ghz wifi, was the only way to have decent bluetooth audio.
