Why Vivo S1 is not able to connect with Da fit?

[Android Central Question]

I am unable to connect with Da fit to Fireboltt smart watch.

Welcome to Android Central! Sorry, it's unclear what you're asking. The thread title says you can't connect your Da Fit band to your Vivo S1 phone, but your post says you can't connect the Da Fit band to your Fire-Boltt watch (not sure why you'd want to do this). Which is it?
