Sample Advertisement keys and data for testing

I’m developing a NodeJS plugin for Signal-K that updates the server with Bluetooth sensor information. I’ve implemented connections to a variety of VE products but cannot reliably test and further develop the Victron modules without access to Victron hardware.

Is there a repository of fake advertisement keys and fake encrypted data that I could use to script some simple tests?

Also, is there any documentation on Victron GATT services and characteristics (in the absence of an advertisement key, my Victron modules will try and make a gatt connection).

The code is here:

Thank you.

PS Currently walking the docks of my marina with a laptop in search of unprotected Victron devices so I can test. It’s not a good look.
