I don’t know why the example in Tai Chi Maker cannot get the return data and displays 307 redirection. I personally think it is because of the http access method. In actual operation, if you use the connection character of http + data, the browser will automatically jump […]
Interaction between ESP8266 microcontroller and RGB LED strip: Simple C language RESTful API implementation guide

MQTT framework construction: ESP8266+PlantformIo+QT
MQTT framework construction: ESP8266 + PlantformIo + QT MQTT is a lightweight communication protocol based on publish and subscribe. It completes the construction of MQTT hardware client and QT software client respectively. After the entire framework is completed, data collection can be completed directly or indirectly through ESP8266 to complete the whole process. Based on […]
