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 […]
Atlas200l DK A2 uses AX210 wireless network card to connect to WIFI

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 […]
Hyper-V installs Centos + configures Centos repo + solves the problem of wifi connection and fixed IP access to Cetos + other fragmentary issues + remote access (reprinted + modified version + supplementary version of the problem + supplementary part)
In the past year or two, I have been using a laptop provided by the company. Due to security restrictions, I cannot install some virtual machine software, which makes me always feel troublesome during the learning process. Therefore, I have always wanted to try a free virtual machine software, using Windows The built-in service Hyper-V […]
Android13 Ethernet and WIFI coexist
1. Introduction In actual project development, especially when Ethernet-related functions are used, it often involves the situation where WiFi and Ethernet are turned on at the same time. Android has very little native compatibility for this. Only one will take effect, and Ethernet will be used first. Therefore, the system mechanism needs to be changed […]
