Argon BLE Example

I’m not finding any documentation/reference on the BLE functionality of the Argon.

Is there a good example and library for the BLE functionality for the Argon?

That's because it's not implemented yet.

The forum search does reveal some threads about that fact

Hey rppolicy,

Unfortunately, the BLE API is not yet exposed for end developers. Our current ambition is to have this API exposed by the end of Q1.
