has anyone of you successfully used Berlins E-Scooter Sharing system COUP with the KEYone? Unfortunately the Bluetooth connection to the scooters does not seem to work for me (other things like connecting my phone via bluetooth to a Hifi-System work fine though). The app always says something like "connecting to the scooter", but nothing will happen.
not sure if this helps - I'm using an app for bike sharing in Singapore called OBike which uses Bluetooth, location and QR code. Has rarely ever failed me. Sometimes you need to press a button on the scooter to "wake" its Bluetooth.
