I am working with some #embedded #esp32 #websocket for #ClassQuiz. It took me hours why the websocket connection would seemingly random collapse. Now I figured it out after debugging for hours: I configured a timeout for the network socket on the esp32. At least I found it after setting up Wireshark and later #mitmproxy with custom CA certificates... What gave me the final hint were the exact 2 seconds between the websocket opening and closing. #embedded #rust
