I upload the firmware from github user tuanpmt’s “espduino” project to my ESP8266 ESP-01 wifi breakout board. This involves grounding GPIO0 and using a python script (provided) to upload the firmware image.
When used in combination with an Arduino, it allows the Arduino to function as a wireless MQTT client, unlocking all sorts of IoT potential. I’ll cover this in a future video.
