Hey! Sorry for the issue with the KBA being behind a login. I've started the process of getting that fixed. It should be public, that was an oversight.
The particular example you chose does not officially support the Proto kit you have. So, yes, you probably need to tweak it for a different pin set. I'll ping the actual author of that example.
And, as for the actual target device... " I found the target MCU as CYBLE-416045-02..." I saw it on the kit itself (magnifying glasses are good things). BUT, I agree that kit web pages an dkit documentation should identify the actual device: DUH!
