Is your ESP32 C3 Super Mini randomly dropping off WiFi or losing Bluetooth?
You're not alone — and here are 3 methods that actually work.
The ESP32 C3 Super Mini is an incredible thumb-sized microcontroller with built-in WiFi and Bluetooth, perfect for makers and developers. But many users (myself included) experience loose connectivity caused by a mix of hardware design quirks and software settings. In this video, I walk through the 3 most effective fixes I've tested personally.

Code:
///// Arduino /////

///// To Set The Max TYX Speed /////
#include "esp_wifi.h"
void setup() {
// Set max TX power to 8.5 dBm (the most stable value reported by users)
esp_wifi_set_max_tx_power(WIFI_POWER_8_5dBm);
// Your normal Wi-Fi initialization here
WiFi.begin(ssid, password);
}
///// yaml /////

wifi:
output_power: 8.5dB
///// To Disable Bluetooth Controller /////
-----------------------------------------------------------------------------
#include "esp_bt.h"
void setup() {
// Disable Bluetooth controller
esp_bt_controller_disable();
}
