Pi top & bangle.js

is here anybody who has got any experience to work with the pi top & and the espruino bangle.js? i get today the hackable bangle.js and i am trying to update the apps on the smartwatch. At first i had the issue that the chromium browser isn’t supporting the bluetooth connection from the browser to the advice, so i had to enable exprimental web platform features in the chromium browser, though now the uploading settings aren’t making any progress, the process stucks in the beginning of the upload. Does anybody know if it’s advisible to disconnect the bangle.js now of the bluetooth connection in the process of “uploading”?
