Parrot Starck Speaker pairing issue with Apple TV4

From the manual:

1. Press the button with the Bluetooth symbol on the control panel. The icon starts flashing. (Discovery mode)
2. From your connecting device, search for Bluetooth peripherals.
3. Select “Parrot by Starck”.
4. You are prompted to enter a PIN code. Enter “0000” on the device that you want the speakers to connect to.

If for any reason the device wants a different fixed PIN number, then you can change the PIN with a computer. See your manual for details.

… but Apple TV4K gives random 4-digit PIN …

‘Random’ as in a number without order, or ‘random’ as in a different number each time you try?

If it asks for the same number each time you try, then you can change the PIN for the speakers to that number, so that it will match the next time.

Else you may have to ask Starck Support.
