ESP32-iUART: A Wi-Fi UART console for debugging installed devices

An engineer has built ESP32-iUART, a Wi-Fi UART console bridge using an ESP32 microcontroller to debug installed target devices directly through a browser interface. The tool connects to the target device's TX, RX, and GND pins, operating locally without requiring changes to the target firmware. It addresses heavy serial traffic by implementing a 32 KB ring buffer, a response limit of 8 KB, and options to suppress chatty terminal lines. Open article →
