@meetulr Comments please

[meetulr]

Yes, this is what I had in mind.

@lokeshwar777 I'd be better for the sake of clarity if you added a comment specifying what the check is doing, i.e. we're first checking if a connection already exists, if not, then only we're establishing a new one.

Please add the check comments so that we can review and merge
