Hi @acaliaro - it's been a while since this issue has been posted. Is this still an issue for you?

I would think this is actually the correct behavior indicating that the socket connection from wifi A is no longer active/valid.

If you'd like me to take a look, could you share a snippet of code to reproduce how you are using the client?

HI It's been a long time and I honestly can't remember whether or not this problem has been fixed. We are not currently using this type of device, but we will probably have to go back to testing soon. I will update you thanks

Hi @acaliaro - understood. Thanks for the update. Let us know if so. I'd be happy to investigate.

Hi all, I've added a feature request #623 to improve the PINGREQ <--> PINGRESP behaviour during network changes.

Thanks for pointing this out!
