Since I can’t currently keep my raspi node running (for reasons), I tried switching my Sparrow wallet to connect to my Bitcoin core pruned node (running on the same device as Sparrow).

Get this error message:

‘Error Importing Bitcoin Core descriptor wallet

The connected node is pruned at 2023/02/15 but the wallet birthday for Sparrow CC wallet is 2022/10/07.

Do you want to try using the existing legacy Bitcoin Core wallet?’

(I said no, because I want to use Sparrow/CC)

Any ideas on next steps much appreciated! 🧡

Your pruned node doesn’t have data before 2023-02-15 but your wallet is older than that. Your other option is to connect to a public Electrum server.

Gotcha, so if I want to use core (rather than electrum) is the only way to redo it, and can I set the pruning date to before my wallet creation?

You can convert it from a pruned to a full node by changing the config file and restarting. But a full node will require 500GB+ of drive space.

If you are able to copy the existing data from your Raspberry Pi node you could avoid resyncing the full node too. Otherwise it could take several days+ to sync your node after you change the configuration and restart.

On Windows the bitcoin.conf file is located in the %APPDATA%\Bitcoin directory.

To change to a full node try this:

1) Stop the Bitcoin node software.

2) Locate your bitcoin.conf configuration file, typically found in the Bitcoin data directory.

3) Edit the bitcoin.conf file and either remove the prune configuration line or set it to prune=0.

4) Save the changes and restart your Bitcoin node software.

Thanks so much! I have a Mac, sorry should have mentioned that.. but sounds like should work the same or no?

Yeah, location of the file is different but otherwise the same process.

On macOS, the bitcoin.conf file is located in the ~/Library/Application Support/Bitcoin/ directory. You can access it using Finder by clicking on "Go" in the menu bar, then selecting "Go to Folder" and entering ~/Library/Application Support/Bitcoin/.
