What device does the Bluetooth Dongle control ?
Make and model is needed. It might need a driver.

It's a desktop box of unknown origins - sorry I can't be more specific
than that. It's probably about 3 years old so not entirely out of date.

Does it control a mouse, keyboard, speakers, etc

None of the items that you mention - I want to use it for my iPhone to swap files, pictures etc.

Need the make and model number of the dongle to find its Linux driver.
Some of the dongles only have a windows driver for them.

Bernard, I've come to the conclusion that this dongle is at fault. There is no brand name or model on the device so that is no help. These things are cheap enough so, next time I pass his shop, my trusty supplier can expect a visit!

Thank you for your efforts - much appreciated. Best wishes for a great 2023!
