Verwenden Sie entweder die UF2-Methode (Ziehen und Ablegen) oder die mehr Schritte umfassende Arduino-Upload-Methode. Für die UF2-Methode

* Laden Sie die UF2-Datei für den raytac-Dongle in der\_ [*aktuellen Version*](http://github.com/acecentre/relaykeys/releases/latest)\_\_ herunter.
* Halten Sie die Reset-Taste gedrückt, während Sie den Dongle an den Computer anschließen. Sie erhalten dann ein USB-Laufwerk auf Ihrem Computer. Ziehen Sie die UF2-Datei per Drag & Drop in das Stammverzeichnis dieses Laufwerks.

Oder die Arduino-Upload-Methode.

* Überprüfen Sie die Einstellungen Ihrer [Arduino IDE](https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/arduino-bsp-setup) (denken Sie daran, dass wir das nRF52840-Board verwenden!)
* Laden Sie den [sketch](https://github.com/AceCentre/RelayKeys/blob/master/docs/arduino/arduino_nRF52840/arduino_nRF52840.ino) auf Ihre Feder hoch.
* Führen Sie den serverseitigen Code aus.
* Geschafft!

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.acecentre.org.uk/products/relaykeys-german/installation/supported-boards/raytac-dongle-nrf52840-usb-key-with-tinyuf2-bootloader-mdbt50q-rx.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
