With OWL IoT, you can easily set up your Ducks right from your browser. The built-in firmware flasher lets you configure and flash your devices in just a few steps.
Before you start
You will need to first create a MamaDuck or PapaDuck under the /network page. Go to the devices page and click add new device.
1. Connect Your Device
- Plug your DuckLink (T-Beam) device into your Mac or PC using a USB cable.
- Important: Use a Chromium-based browser (Google Chrome, Microsoft Edge, etc.). Other browsers do not support Web Serial connections.
- Click Connect Device in the OWL DMS interface.
2. Choose Your Duck Type
Once connected, you’ll move to the Select Firmware screen.
