Hi Knud,

If the LED is giving long flashes continuously that probably indicates firmware corruption. Does the app try to upload firmware when you connect to it?

What version of the app are you using? You should be able to tell by touching the gear icon in the top right of the “scan” screen. If the gear icon does nothing or is not present, it means you are using a very old version.

There is a new version of the iOS app and firmware in the Apple approval pipeline – if you want to try it out earlier I can add you to the beta group but I need your permission and email address.

Best
