Hi,
AP 325 is inbuilt beacon (which acts as indiviudal beacon) when configured with meridian details it start sending the beacon info to controller and to meridian cloud. If it is IAP then it will send data directly to meridian cloud.
AP325>Controller>Meridian Cloud
IAP30x >Meridian Cloud
If have you battery powered beacon and want to manage then you need USB power beacon plug in to APs.
We have meridian cloud (edit.meridianapps.com) where you could create iOS and Android apps that provide your visitors turn-by-turn directions, location and time-based push notifications, and other location-based services.
If you want to create account , please check with your Aruba accounts team, who could help you in getting account in meridian.
Regards,
Pavan
