# Ledger testnet Bitcoin connection

You'll need to install a seperate bitcoin app on the Ledger device. This is only possible after turning on the Developer mode, in settings (top right) and then clicking the Experimental Features tab:

Then click "My ledger" in Ledger live, and allow the device to connect. Searching for "testnet" will bring up the Bitcoin test (BTC) app version 2.2.0-rc2 in this case, install that:

Switch to testnet on the Leather Extension:

And then connect to bitcoin while the Bitcoin testnet app is active on the Ledger device. After connecting you may need a bitcoin faucet, you can try this or find another one online <https://coinfaucet.eu/en/btc-testnet/>.

## 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://leather.gitbook.io/guides/testing/ledger-testnet-bitcoin-connection.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.
