Download CSV File

Hi,

Due to the way our application is implemented, we need to use the MAC address of the beacons for identification.  When I attempt to download the beacon list from the Kontakt panel, the MAC address is not included in the CSV file.  Is there a way to extract this from the database?  We have 400+ beacons, and sifting through them one by one to find a MAC is not feasible.

Thanks,

Terry

  For all nRF52-based devices we divide all possible advertising packets into four groups:

  • Kontakt.io packets (Secure Profile, Telemetry and Location)
  • iBeacon
  • Eddystone (UID, URL, TLM)
  • Encrypted Eddystone (EID, ETLM)

  These beacons use separate virtual BLE broadcasters to send packets from each group. Because of that, packets from different groups have different MAC addresses, so by 3rd party scanners they are treated as packets sent by unrelated beacons.

  However, MAC addresses of Kontakt.io and standard iBeacon and Eddystone packets are sequential and this information can be used to associate various packets with each other. For example, if a given beacon broadcasts Kontakt.io packets with using 12:AB:45:CD:EF:F1 address, then iBeacon packets from that beacon will have 12:AB:45:CD:EF:F2 MAC and Eddystone packets will use 12:AB:45:CD:EF:F3.

  Please keep in mind that sequential MAC addresses apply only to standard, unencrypted and not shuffled packets. It means that Eddystone EID and ETLM packets, as well as Kontakt.io Secure iBeacon and Eddystone packets always use random MAC addresses.
  
  MAC addresses can be extracted from API [getDevice](https://developer.kontakt.io/api-reference/10/#tag/Device/paths/~1device/get). That extracted MAC will be for Kontakt Packet.

  Hello Terry,

   

  Due to the implementation of packet interleaving solution, each beacon can use multiple MAC addresses.

  It is possible to get the MAC address used for Kontakt.io packets from the API and Panel but since the Eddystone and iBeacon use addresses that are randomly assigned when the chip is programmed, the only way is to scan each device individually.

  Right, but is it possible to get that mac address which is in the API exported out to a CSV?
