Install ESP32 in ArduinoIDE

Install ESP32 in ArduinoIDE

Open Preferences and add

to additional boards manager URLs:

Tools -> Board Manager and install esp32

Sometimes your computer needs a restart! Now select FireBeetle as Board and the port it is available to.

Hello World

void setup() {
void loop() {
  Serial.println("Hello from FireBeetle ESP32 board");

Sometimes you run into an error

A fatal error occurred: Invalid head of packet (0xE0)

so it’s good to reduce the upload speed to 115200

When the program is flashed you can connect via Tools -> Serial Monitor
