RFCOMM Issue

Hi,
I have a bug issue with some other bluetooth accessories, when i start zwift.
Error is like RFCOMM serial channel failed (my translation!).
I already tried :

  • remove the Bluetooth .plist file (/Library/Preferences/com.apple.Bluetooth.plist) and reboot.
  • factory reset connected devices (Shift-Option-Click on Bluetooth icon in tray: select “Factory reset all…”
  • reset the Bluetooth module (Shift-Option-Click on Bluetooth icon in tray: select “Reset the Bluetooth…”
    I am on native macos Big Sur 11.6.8, MacBook Pro Apple M1

Thanks for your answer,
Regards,
Olivier
