Hey, so I'm trying to write a plugin that uses bluetooth LE, using this library: https://github.com/thegecko/webbluetooth I have a PoC of the bluetooth code running outside the plugin, but as soon as I add this to the plugin code: I get the exclamation mark icon, and the logs on my mac shows the constant restarting behaviour below. Is there something about the plugin environment (presumably it's just Node?) that prevents libraries with native bindings from working? |

Hi @superslau, Sometimes you can run into issues where import commonjs from "@rollup/plugin-commonjs";
import json from "@rollup/plugin-json";

Hi @ChekTek thanks so much for the above. I went with the rollup copy plugin approach and managed to get things working - bluetooth connections are working, data is being streamed from the device to the Stream Deck, it's amazing. However... it only works if I quit Stream Deck software, and run If I open SD first, and then run |

Hi @superslau,
Sometimes you can run into issues where
npmpackages are meant to be using in the web environment, although it appears that this package should work within Node. Native addons should work for you (Elgato uses them in the Volume Controller plugin), but you will need to include the module inside of the plugin folder. In Volume Controller, we use a rollup plugincopyto move the files into the plugin foldercom.elgato.volume-controller.sdPlugin/bin/node_modules.
