Version After Setup

How do I find what version of Ripple/Meshcore I leave on my T-Deck?

I have 2 T-Decks. One I flashed a month or 2 ago and works fine. The other I flashed today but it keeps telling me that I have invalid characters in the identity name. I just want the same version that is on my first one, to hell with the newest/latest/greatest.

Thanks in advance.
