I am developing (because I couldn’t find an IDF example app) an application where my ROOT_MESH will download and update itself with an OTA image from an HTTPS server (from working example), and then proceed to read the current working OTA partition and send it in fragments of 1024 bytes across the WIFI mesh network using esp_mesh_send.

I am struggling to call “esp_mesh_get_parent_bssid”

First time setting up ESP32 board (Windows 11 , with cp210x drivers installed)

First time setting up ESP32 board (Windows 11 , with cp210x drivers installed)

I’m building my first project on ESP32. I figured out many things regarding programming and wiring.

I have errors when I compile my program after a forced shutdown.
Unfortunately I am new to the Arduino platform and I am struggling!
I have loaded a sample timer program and get the same result as my code.
When I compile the code the following error occurs.
error: too many arguments to function ‘hw_timer_t* timerBegin(uint32_t)’
18 | Timer0_Cfg = timerBegin(0, 80, true);

Thingsboard , I’m having trouble with two switch. I’m trying to integrate a switch widget into the dashboard so that I can control two led, but two switch in the same function i dont know why.
i noted have done when one switch work fine.
this my code

3 esp32 and 3 ultrasonic sensors are used. If one direction is green the rest two directions should be red for certain period of time based on vehicle proximity and the cycle continues. I’ve used various codes for my conditions but none of them worked properly.I expect a program in c/c++ such that i could run that program in arduino IDE and satisfy my conditions.

necesito ayuda para poder conectar un ESP32 via HDMI directamente.
Necesito crear una NES, y para eso necesito conectarlo via HDMI para que transmita tanto video como sonido, pero no se como hacerlo por eso necesito ayuda..

the uart serial monitor did not show the right values which i want to see. this error mostly occur when ever i am using Wi-Fi library.
