I am having difficulties getting my existing website on my ESP32 to work together with the WIFI mesh network. How do I setup the wifi settings to use the ESP WIFI MESH while also serving a website for configurin
I can execute the command for esp_err_t esp_wifi_set_country(const wifi_country_t *country) I have set the country to "US" with out getting an error. I can not execute the command esp_err_t esp_wifi_get_country(const wifi_country_t *country) country variable type I use is char*...
In this article, we will show how to use ESP-WROOM-32 to get real-time data from the air quality sensor and display it on the ThingsBoard dashboard. To send data to Thingsboard we will use ThingsBoard Arduino SDK. Preparation Arduino libraries: -WiFi -MQUnifiedsensor -ThingsBoard Arduino SD...
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 will be responsible forread(1)/ write(0)operation. If you plan to ...
Re: how to use read-protected eFuse ? PostbyJonathan2892»Mon Jun 03, 2024 3:31 pm Hi, does that mean, that after read-protecting all efuses it is impossible to read the MAC with esp_efuse_mac_get_default() ? Is there any way to get the MAC? I mean WIFI need it to connect...

向ESP32 HTTP服务器添加CORS-Header,即跨域资源共享头,可以通过以下步骤实现: CORS(Cross-Origin Resource Sharing)是一种机制,允许服务器在响应中添加特定的HTTP头,从而允许跨域访问。在添加CORS头之前,客户端(浏览器)可能会因为跨域限制而阻止访问。 在ESP32上实现向HTTP响应添加CORS头的关键步骤如下: 在ESP32...
Program for ESP32 Analog to digital converter So we are using Arduino IDE in these tutorials. Arduino IDE provides a built-in function to read analog values that areanalogRead function. analogRead(analog_pin_number): We will use this function to read analog value. This analogRead function has ...
How to use an ESP32 + Omnivision-based camera module to make it remote accessible Introduction Creating a locally accessible camera application with the ESP32 is something that has already been done. But why do you need a camera that you only can access on your local network? You can just...
