Original Question:
Im using DW1820a card connected over m.2 slot ofr Bluetooth and WiFi. I'm having issues with bluetooth loosing connection once every a while. Sometimes it returns after a minute or two, other times I need to restart the computer. Also noticed that when someone calls on my iPhone, and mackintosh is trying to handle connection, bluetooth disconnects. Is there something I can do to prevent this? Kext related to Wifi and Bluetooth I use are: AirportBrcmFixup.kext, BlueToolFixup, BrcmFirmwareData, BrcmFirmwareRepo, BrcmPathRAM3. Also have USBPorts map kext prepared.
