What can I do to ensure that I don't disconnect，I am currently keeping the link from breaking by recreating the DataChannel，That doesn't seem like the best way to do it

chenqinggang001 commented 1 day ago

I find that when the receiver sends a "ping" message after receiving the message, the link will keep active. Is this correct?

paullouisageneau commented 17 hours ago

It looks like you destroy the data channel. Are you sure you keep a shared pointer to it? Sending a ping probably has the side effect of forcing you to keep a pointer.
