Assertion error when connecting to python-socketio server

Open JeremyVarghese opened this issue 4 years ago • 1 comments

I created a socketio server and tried to connect an esp32 to the server. On the server side, it is showing that it is connected but on the client side, on the esp32 by using the following code uri='http://192.168.56.1:5000' with usocketio.client.connect('http://127.0.0.1:5000/') as sio: it shows an assertion error on line 123 of client.py File "usocketio/client.py", line 123 in connect Assertion Error To test what was wrong, I added a print line before that line packet = socketio._recv() print("packet:",packet) ####### assert packet == (PACKET_NOOP, '') which gives an output packet: (None,None)

I am new to websocket communication and event driven programming is best suited for my usage but I am unable to understand what the error is.

It looks like you're possibly timing out before receiving a packet and it's not okay with that. I'm afraid you'll have to debug this on your own. If you want to try using more conventional web-driven programming, try the branch in this PR: https://github.com/danni/uwebsockets/pull/13
