Is it possible in theory to use SignalR Core in Meadiw?

#1

Hi, I was trying to connect to a aspnetcore.signalr server and Meadow kept hanging on connection.StartAsync(). I am starting to think that it is not possible. Any thoughts?

Thank you

#2

Did you get a way around it ?

No. I set the project aside for now. I might give it another try with the new updates

I started playing with this project again.
I got my board to connect to the HUB but it still hangs on StartAsync(). With client hubconnection console logging from Meadow, I know a bit more. It seems that it hangs when starting the WebSocket transport. To be honest, it is over my head for now. But I’ll probably dig a bit deeper this time.
