Ledger Transport HID

This package provides a alternative to @ledgerhq/hw-transport-webhid. I would suggest using that package instead unless you are having problems with it.

Main features of this package:

• Smaller bundle size (No dependencies)
• Only using web-natives so no polyfills needed
• Better error recovery

Usage

import { LedgerTransport, StatusCodes } from "ledger-transport-hid";

const [device] = await navigator.hid.requestDevice({
  filters: [{ vendorId: 0x2c97 }],
});
const transport = new LedgerTransport(device);

Example methods

// Read the version and name of the currently open app
// Throws an error if no app is open
const response = await transport.send(
  0x00,
  0x00,
  0x00,
  0x00,
  new Uint8Array(230),
  [StatusCodes.OK]
);

const [major, minor, patch, ...appName] = response.data;
const result = {
  major,
  minor,
  patch,
  appName: new TextDecoder().decode(new Uint8Array(appName)),
};
