      initialBaudrate={115200}
      initialDebugLogging={false}
    >
      <ESPProgrammer />
    </ESPLoaderProvider>
  );
}

function ESPProgrammer() {
  const { state, actions } = useEspLoader();
  
  const handleConnect = async () => {
    await actions.connect();
  };
  
  const handleFlash = async () => {
    const files = [/* your ESP files */];
    await actions.program(files);
  };
  
  return (
    <div>
      <p>Status: {state.isConnected ? 'Connected' : 'Disconnected'}</p>
