Pierre,
The AS-100 should be provisioned and configured with the 'Beacons' app that is available from the Apple App Store. Configuration is done from the Meridian App platform (edit.meridianapps.com).
CLI configuration is not recommended, nor supported.
Please make sure that you updated the Beacons App to the latest version, and you are close to your sensor (within few feet/meter). If you have another IOS device available, it may work to retry with that. If you still have problems that the Beacons app does not communicate properly, please contact the HPE Aruba TAC.
