Missing Handshake Notifications in channel

[SX91]

Hello!
I've used the approach similar to the proposed one here, but sometimes the connected peer is not being registered.
Seems like it happens because the StateMachine.hsNotifyc is created as unbuffered channel, and writes to this channel are non-blocking (select + default), thus "skipping" some notifications if the receiver is "slow".

Any suggestions how to make notifications reliable?

I have the same experience. When two clients connect at the same time, the handshake notification from one of them is missing

Happy to try and review a patch to resolve this

Would it be a problem to make the hsNotifyc channel buffered? If there were no consumers, a few messages would remain in the channel, but that wouldn’t matter, would it?
