I use Pin 34 for RXD-0 35 for TXD-0 27 for RXD-2 28 for TXD-2 Works fine Have you seen this? You mean using GPIO pins, as GPIO pin numbering is different than board's actual pin numbers? Thanks. GPIO9 and GPIO10 do not work with UART1 because they are internally connected to flash. You can other pi...

First, you need to install the file system uploader plugin in Arduino IDE and then you can upload files. you can refer to this article: https://microcontrollerslab.com/install-esp32-filesystem-uploader-in-arduino-ide-spiffs/ For esp-idf, you can refer to this: https://docs.espressif.com/projects/esp...

#include <HardwareSerial.h>

HardwareSerial SerialPort(1); // use UART1

void setup()
{
SerialPort.begin(15200, SERIAL_8N1, 4, 2);
}

ESP32 dev kit.

I have myself followed the same tutorial and used the HardwareSerial example in that tutorial and changed UART2 to UART1 in the example code, it worked fine for me.

I have found many tutorials online where they used both WIFI and ESP-NOW simultaneously with Arduino IDE. In this tutorial, they are receiving data from other esp devices over esp-now and sending to a web server with WiFi in STA mode. https://microcontrollerslab.com/esp32-e ... eb-server/

Yes, it gives issues when we install esp-idf directly from VS code and I also faced the same issue. You can install esp-idf from the installer and then integrate it with esp-idf. I follow this guide: https://esp32tutorials.com/install-esp3 ... e-vs-code/ and it worked for me.

Default pins for UART1 (GPIO9 and GPIO10) do not work. Because they are internally connected to flash. You can use any other GPIO pins. You can check this tutorial: https://microcontrollerslab.com/esp32-u ... s-example/

I am not sure but you can refer to these APIs to see which API to call to remove persistence storage information: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/bluetooth/esp-ble-mesh.html But other than this you will also need to implement a logic which will inform a prov...
