Bug: BLE Device does not work

[FgPy93]

Describe the Bug

Got a Switchbot Bot. Wether it was declared as switch or press mode neither works.

The prerequisites for the BLE mode were met as far as I can tell from the docs. Identification of the switchbot works with the bluetooth of the raspi. But the communication via the plug-in does not work.

To Reproduce

Add Switchbot Bot to Homebridge Setup on Raspberry Pi.

Expected Behavior

Depends: When declared as switch an error code is espected. Declared in "press" mode nothing happens.

I bought the switchbot a few months ago and was really excited to add this to homebridge, and this plugin has not worked once. There have been updates to the app and I have gotten different error messages, but I am now receiving this same error as well when trying to connect through BLE.

FYI: This error was already mentioned in #980 and #977. Im Running into the same error.

Hi there. Running into the same error with Switchbot plugin v4.3.1 on Homebridge v1.9.0 on a Raspberry Pi 3B today.

The connection itself seems to work fine: The Pi can find the BLE MAC of the Switchbot when running bluetoothctl via the Homebridge Terminal, and the device also shows up in my Apple Home app with (seemingly correct) metadata.

However, nothing happens when I click on the device button in either the Homebridge UI or the Home App on my phone.

I started some live logs while clicking on the device in the Home App and discovered the same error:
