HID problem on Raspberry PI (Failed to initialize gatt-client)

HID problem on Raspberry PI (Failed to initialize gatt-client)

[Sailor Jerry]

I'm trying to pair the remote control to the Raspberry PI running:
Linux 5.4.83-v7l+ #1379 SMP Mon Dec 14 13:11:54 GMT 2020 armv7l GNU/Linux

The BT remote is connected and I see the input coming in btmon, but it
fails to appear as HID input.

This is the output of bluetoothd:
