Issue

I can't seems able to figure out how to connect to a L2CAP bluetooth device it always give me error says "ValueError: invalid protocol"
This is my code

remote = bluetooth.find_service(address=macAddress)[0]
# print(remote)
# print(bluetooth.L2CAP)
s = bluetooth.BluetoothSocket(bluetooth.L2CAP)
s.connect((remote['host'], remote['port']))
s.recv(4000)

also on top of that i tried to print(bluetooth.L2CAP) and it gave me value 0

The device i am trying to connect is Amazon FireTV remote. Also from this info it looks like for me that it uses L2CAP

L2CAP on Windows is never supported due to WinSock Bluetooth mode only have RFCOMM support. Apparently in order to be able to talk to other devices with Microsoft Bluetooth stack you have to write a kernel module that directly uses the low level Bluetooth API in kernel mode.

So how do I do that? do u have a doc that you can link to me

wait at https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/bluetooth-driver-stack it says

RfComm- The component that implements the Bluetooth serial cable emulation protocol. RfComm also uses the L2CAP and SDP interfaces found in BthPort. The upper edge of RfComm exposes the TDI interface, allowing this component to appear to be a networking transport. This is how WshBth connects to Bluetooth to send and receive data from user-mode APIs.

it says RFCOMM uses L2CAP. also a question If the L2CAP wasnt supported then how is this L2CAP BT device connect to this Windows?

it says RFCOMM uses L2CAP.

Yes. However there's no low level L2CAP support. Only RFCOMM.
