Advertisement and scan response frames for unknown devices are stored in raw format, that is, the payload for each frame type is stored as a hexadecimal string, along with the RSSI value. BD maintains a database of IoT devices with attributes populated for known or classified devices and complete advertisement or scan frames for unclassified devices.
Transport Interval. The transport interval determines how often IoT or BLE data is sent from BD to BR. ArubaOS supports the following transport intervals:Asset tag RSSI data is sent every 4 seconds from each AP to MeridianAruba beacon management data is sent every 30 minutesIf I understand this, the BR is the BLE Relay, another program that runs on each individual AP. The BR collects the beacons it hears from the BD process, and, if configured correctly, it can push them somewhere of your choosing: either an HTTPS POST to somewhere, or over a websocket. This has to be done on each individual access point, in my case that's thousands of them. They then all individually will HTTP POST their 'heard beacons' tables to an endpoint of my choosing.This leads to some questions, based on my limited understanding of how this works.First, is the format of these messages defined somewhere I can see (a url etc.)? I gather that if it is HTTP POST that it's JSON (what's the format?) and if it's via websocket it's protobuf (where can i find the .proto definitions?)Second, if I have this right, then I'll need to stand up a server that can handle a LOT of concurrent connections (7,500 access points). Do I have that right? Can these APs be configured to only send changes?Third, there is some notion of filtering. That might be useful for me but I think to do that I would have to maintain a list of UUIDs and push them to every single access point. Do I have that right? I don't think I can use this but I still would like to know how it works. It sounds like a useful way to limit traffic, but I might want to limit what users see what (i.e. have multiple whitelists). Based on that, I think I need to have my own central server receive everything, then filter based on the individual user or client.Finally ... if I bought just one aruba access point for home (like an AP22) could I experiment with all of this without being tied to the full campus environment, Aruba Central, etc.?--Chris
