Python library to communicate with Ledger Blue/Nano S
Project description
Ledgerblue - Python tools for Ledger Blue, Nano S and Nano X
This package contains Python tools to communicate with Ledger Blue, Nano S and Nano X and manage applications life cycle.
Installation
It is recommended to install this package in a Virtual Environment in your native environment (not a Docker image) to avoid hidapi issues.
python3 -m venv ledger
source ledger/bin/activate
pip install ledgerblue
Supported devices
At the moment these tools work for all Nano S, Nano S+, and Blue devices, but only for special Nano X developer units which are not available to the general public. The Recover scripts, will work with Nano X starting from a specific version.
Please check Ledger Developer Portal to see how to debug your application on a Nano X simulator using Speculos
Installation pre-requisites
- libudev-dev
- libusb-1.0-0-dev
- python-dev (python >= 3.6)
This package can optionally work with libsecp256k1 Python bindings compiled with ECDH support. If you wish to enable libsecp256k1 bindings, make sure to install libsecp256k1 as follows:
SECP_BUNDLED_EXPERIMENTAL=1 pip --no-cache-dir install --no-binary secp256k1 secp256k1
To install the custom secp256k1 package on MacOS, you previously need to run:
brew install libtool
Which would end up installing glibtool and glibtoolize utilities required for the build process.
Giving permissions on udev
When running on Linux, make sure the following rules have been added to /etc/udev/rules.d/:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", MODE="0660", TAG+="uaccess", TAG+="udev-acl" OWNER="<UNIX username>"
KERNEL=="hidraw*", ATTRS{idVendor}=="2c97", MODE="0660" OWNER="<UNIX username>"
