Application example of upgrading related functions based on ESP32 development board using MiSiQi application WIFI (key/advanced)+EEPROM+MQTT+OTA
I am an amateur electronics enthusiast and can use Chinese programming such as Yi Language and e4a. I have recently played with several microcontroller development boards and used MiSiQi for programming. I found that MiSiQi is good at simple programming but has more complex functions. Programming is difficult to use, especially for friends like me […]

Analysis and solution to the problem of large ping delay on wifi 4 devices
The customer has a HUD head-up display device. After connecting to our wifi device, the ping delay is very large, more than 1 second, and the TCP transmission head-up display data delay is very stuck. After getting the HUD device, I started to test 3 ublox wifi: Problem summary: The HUD device in the g/n […]
