Before installing ESP32 package in Arduino IDE, it’s crucial to ensure that you have the latest version of Arduino IDE. ESP32 has been known to have compatibility issues with previous versions of Arduino IDE. Therefore, we recommend deleting any old versions and installing the latest ones to ...
The i2c_master_init function will be used to initialise the I2C in the master mode. Here we will first configure the I2C parameters, which are as followsmode sets the mode for the I2C. It can be either master/slave. Since we want the ESP32 to be a master, we will set the I2C_...
if you are not going to perform OTA on the device (i.e., you aren’t going to update the code of your ESP32 remotely, after it is deployed), you can choose one of the No OTA options, or even the Huge App option. If you are not going to use...

I'm trying to check whether the ESP has reset from an upgrade (USB or OTA) to reset my "reset_counter" variable which is stored in flash. I tried to detect that from the response from the function nvs_get(). If I get a "value not initialized" then it means I had a code upgrade...
As provided in the above, I tried changing the mode to WIFI_MODE_STA and tried to communicate. Socket is created successfully and bind to the port. But I am getting an error "Error Code 118" while sending the payload. Do I need to disconnect using esp_wifi_disconnect(); before changing...
Step 2: Upload the ESP32 Bluetooth Code Once the ESP32 board is installed, you will see different pre-installed libraries and their examples in Arduino IDE. All these libraries are related to the ESP32 board. For Bluetooth serial communication, we are going to use the ESP32BluetoothSerial.h...
After the power was lost, I have to restart ESP-NOW as quickly as possible. Basically, my ESP32 S3 Wroom2 needs about 46ms to call app_main. esp_wifi_init() needs about 2.5ms, while esp_wifi_start() needs 30ms. Is it possible to speed this up? In particular esp_wifi_start()?
