Esp32 cannot connect. I have used my computer to test that WiFi has 2.4G band and can be connected through 2.4G band. What should I do to connect the eps32 to the router through the 2.4G band? Who has experienced similar problems? Can you help me? thank you very much!
Re: How to connect to wifi network while in APSTA mode? Tue Jun 20, 2023 10:37 pm Yes, you can freely change WiFi mode without needing to completely stop and restart the driver. eg. Code: Select all esp_wifi_start(); esp_wifi_set_mode(AP); esp_wifi_set_config(AP, &ap_conf...
Hello, I am trying to get my ESP32 in sta mode to connect to different wifi networks, the esp initially connects to an ESP32 in AP mode, that is, an ESP32 in server mode, the code does all the configuration so that it can connect via wifi to the ESP32 in ap mode and also for...

i am new to ESPRESSIF Wifi module. I am using ESP32-MINI-01 module with PC/Chip using AT commands in my project. The main application scenario of my project is biased towards real-time data transmission. The process of using it all went smoothly. However, when testing the distance, it ...
MQTT Broker:The broker receives all messages, filter the messages, determine who is subscribed to each message, and send the message to these subscribed clients. Now, in this tutorial we will explainhow to connect to a MQTT brokerand subscribe to a topic usingESP32and Arduino IDE libraries. ...
ESPnow is a protocol to connect one Espressif device to another over WiFi , such as ESP32 or ESP8266, WEMOS etc. the advantage is that it is not relying on local WiFi network, so no need to select a WiFi Network and register to it with a password. I…
In this manner, we can connect up to 8 LCDs to the same line. There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here...
