This is where one Bluetooth dongle is in the Sending device * Wireless Mode. This is where a Bluetooth dongle plugged into a power outlet or a battery sits away from the Sending device. This might be useful for devices where you cannot plug anything into the sending device * Wired + Receiving Dongle. A receiving dongle sits in the receiving device. This is useful where "pairing" is unreliable on the recieving device or there is no Bluetooth stack on the receiving computer. You need to decide what is best for you. --- # Agent Instructions This documentation is published with GitBook.

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/installation/connecting-with-relaykeys.md?ask=&goal= ``` `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.
