Connect it to the master device via UART and use the terminal on the built-in web page for debug logging, |

remote control etc. It works like a simple LCD screen, in a way. |

It's tested with 1.5.2, 2.0.0 won't work without adjusting the build scripts. Any 1.5.x could be fine. |

The `esp-open-sdk` Makefile could also download this for you with the right flags. |

The IoT SDK is now included in the project due to problems with obtaining the correct version and patching it. |
|

It works with version 1.5.2, any newer seems to be incompatible. If you get it working with a newer SDK, a PR is more |

than welcome! |

It's kind of tricky to develop the web resources locally; you might want to try the "split image" |

The Makefile should automatically build the parser and web resources for you when you run `make`. |
