Remote debugging is an essential feature for any embedded system, including Arduino-based projects. The ESP8266 WiFi module has gained popularity for such applications, especially when used with ESP-LINK firmware. This article aims to guide you through setting up an enhanced remote debugging environment using Arduino, ESP8266 (NodeMCU and ESP01), and ESP-LINK firmware.
We have already addressed the topic of remote wireless programming via Bluetooth of an Arduino UNO in our previous article titled “Arduino Remote/wireless Programming” however, thanks to the feedback and questions from our readers, we have decided to delve even deeper into this subject, exploring the possibilities that WiFi connectivity offers.
ESP32 have 2 multiple UART, they are very usefully for debug, and this device have also a core logging system that you can use to debug and control your code.
WeMos D1 mini have 2 UART, one on dedicated pins and a transmit-only UART that can be enabled on GPIO2 (D4), It’s very usefully for debug.
