Hello Forum,
I'm trying to connect an arduino nano 33 BLE over Bluetooth on Windows 10.
It is recognized but when I try to connect it, it just stays trying to connect and prompts a warning saying the is an issue. No further info.
Has anyone had success while trying to connect one?
Thank you very much.

How are you trying to connect?
With BLE in most cases you should connect from an app and not from the operating system. The OS UI is usually only used for pairing.
The ArduinoBLE library does not support pairing and therefore all attempts to do so will fail. Pairing is an optional feature in BLE and not required for most Arduino use cases.
Unfortunately, the support under Windows is not great. What I got working is using BLE from the web browser using the Web Bluetooth API, JavaScript and HTML5. Here are a few links I found useful.
