Thank you for your help Philip, I am pretty sure that they are enabled, I test with mutiples mobile phones, none of them is showing up.
What is showing up, the Jawbone fitness tracker, two bluetooth earphones (they are on, but the meraki only show them for like one entry and the rest is off, which is wrong). A Mac OS notebook(is scanning correctly), and themselves(2x MR32).
Iphones and Android, nothing, even if the time period for sending beacons is 10 minutes, they never show up, even when a device is been pared or something like that.
