This is a custom ESP32S3 prototyping board i built to troubleshoot the issues. It Started With a Simple Problem I was testing the EvilCrow Cable Wind — a USB HID device built around the ESP32-S3 that executes keystroke injection payloads over WiFi. Everything seemed fine: the keyboard HID was typing correctly, the web interface loaded, basic commands like RunWin worked. But ServerConnect and ShellWin did absolutely nothing. No error. No feedback. Just silence. Digging Into the Code The first thing I found was this pattern — repeated across four commands: ORIGINAL — DANGEROUS if (!clientServer.connect(serverIP, serverPort)) { while(1); // hangs forever if TCP fails } ⚠ Critical Bug If TCP connection failed for any reason, the device entered an infinite loop with no timeout, no error output, and no recovery path. Ever. But there was more. The bugs were stacking: critical TCP failures were environmental: listener ...
I tested the communication between PC and Micro controller and finally my tests was perfect. I send an "Hello World" message to PC and from hyper terminal i am able to see the message. Bingo this is another way we can view data other than an LCD.
Later code for the temperature sensor and now the temperature is monitored using PC. So this way we can monitor remotely. I think i should by some wireless modules to interface the micro controller to send data. hope soonnnn..
