[BUG] BLE data converter not working with latest BLE connector remake from master branch

[jayneev]

Describe the bug BLE attributes read for BLE UUID "00002A00-0000-1000-8000-00805F9B34FB" (corresponds to standard BLE connected 'device name') reports Exception error. (Please refer corresponding UUID, below ble.json config - "attributes" section) This issue is raised separate based on triage with earlier issue thread named "[HELP] Can't read data with new BLE connector #655"

Connector name (If bug in the some connector): BLE Connector

Error traceback: BLE Device name ====> "name": "CMx9", (Please refer to ble.json config below)

@jayneev, we have investigated the problem with converting data, so for now I am working on fixing it. I will let you know when it is done.
