BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.
With an iPhone, plug BitBox02 Nova into the phone or another suitable power source. It uses Bluetooth to exchange data. Ethereum needs the Multi edition; the Bitcoin-only edition cannot be changed to Multi.
