IoTy Firmware Flash Tool

Step 1: Connect

This will connect to your ESP32 via Web Serial. For the ESP32-C3-Supermini, you need to hold the boot button while plugging in the USB cable.

Filtered Connect Hides the non-ESP32 devices, but some valid ESP32 devices may not appear.

Connect Show all devices, but may be hard to identify the correct device.

Step 2: Flash Micropython

Click one of the following to load a micropython before continuing. If your device is already flashed with a suitable micropython, you can skip this step.

ESP32: Micropython 1.23.0 (Stable) Micropython 1.19.1 (Legacy)

ESP32-Cam: Micropython 1.22.2 With Camera. No Bluetooth. (Stable.)

ESP32-C3-Supermini: Micropython 1.24.1 (Experimental)

Not Loaded

Baudrate: 921600 460800 230400 115200 Flash Micropython Flashing micropython will erase everything on the device.

After clicking the above button, if the "Connecting..." message takes more than a couple of seconds, press and hold the boot button on your ESP32 until the chip is detected.

If errors occurs, try again with a lower baudrate (...seems commonly required on Mac).

Step 3: Flash IoTy

This will copy the IoTy firmware to your ESP32. For the ESP32-C3-Supermini, you'll need to press the reset button and reconnect before this step.
