Problem description

Connecting a BitBox02 fails.

1. Close all other wallet apps that could connect to the BitBox02
2. Connect the BitBox02 and tap the touch sensor
3. Open MyCitadel
4. Open any wallet file ( or create a new one)
5. Click on "Connect device"
6. BitBox02 asks for password, enter it
7. Error message appears:

Clicking on "rescan devices" crashes and force closes the app.

Connecting a Trezor works without issues.

Goal of this was to try out miniscript support, which came with the newest BitBox02 update.

async-hwi will receive bitbox02 support soon. It could be worth using this to interface with signers, as it is Rust just like this project.

@benma wow great project! That's nearly what we need: wizardsardine/async-hwi#47

[dr-orlovsky]

Ok, I got fixed device detection (it was failing due to a bug in rust-hwi which was sending empty string password to BitBox, which was working before the update) - however now the HWI library fails to sign PSBT. Filed a bug here: bitcoin-core/HWI#706
