How to Initialize TWELITE Firmware

How to restore TWELITE firmware on TWELITE SPOT to the factory default state

This guide explains how to restore the firmware written to the TWELITE mounted on the TWELITE SPOT to the factory default state using the TWELITE STAGE APP.

The TWELITE mounted on the TWELITE SPOT does not allow configuration changes via interactive mode.

To set the TWELITE frequency channel and application ID, send commands via serial communication from the ESP32. In the Arduino environment, use Twelite.begin().

Install the TWELITE STAGE APP

The following is a simplified explanation for Windows. For macOS/Linux instructions or detailed explanations about the TWELITE STAGE APP, please refer to the TWELITE STAGE APP Manual.

Download the TWELITE STAGE SDK and extract the downloaded file directly under the C drive (for Windows).

Obtain the Firmware

Download the binary file from the link below and place it in the BIN folder inside the MWSTAGE folder.

App_Wings_TWELITESPOT_BLUE_L1305_V1-3-2.bin

Connect to the Host

Connect TWELITE R3 / R2

Connect the TWELITE R3 / R2 to the 7P interface (the side labeled TWELITE).

Connect Power

Supply 5V power to the USB-C connector on the side.

Always connect the TWELITE R3 / R2 to the TWELITE SPOT in the same orientation as shown above. Connecting in the wrong orientation may damage the TWELITE SPOT or TWELITE R3 / R2.

Operating the TWELITE STAGE APP

Launch the TWELITE STAGE APP (TWELITE_Stage.exe).
Select the TWELITE R3 / TWELITE R2 in the serial port selection screen.
From the main menu, choose “Rewrite Application” -> “Select from BIN” and write the previously obtained binary (App_Wings_TWELITESPOT_BLUE_L1305_V1-3-0.bin).
