    We plan to release the specification for the Kontakt.io Telemetry packet next week.

    and the parsed values:

    FC:99:XX:XX:XX:XX [a] txPower:97 RSSI:199 BUTON:5083 MOVED:338 ORI:(253, 255, 64)@16 TEMP:26 UTC:2018-03-07 02:31:58 BATT:100 UNKONWN: (25 22 3) (2, 100, 244, 57, 82, 68, 52)

    The specifications of the type/flags:

    Seems the first byte is the packet type (0x03 0x0c 0x11 0x1d)
    Second is the kontakt packet type and length :

    0x03 (every .5 sec)

    • name (0x09..)
    • txPower (0x0209)

    0x0c (every 1 sec)

    • last button press (0x030D)
    • UUID (0x020106) +3 unknowns

    0x11 (every .5 sec)

    • unknowns (0x0801)
    • UUID (0x020106) +3 unknowns

    0x1d (every 1 sec)

    • time stamp and batt level (0x0601)
    • temperature (0x0305)
    • orientation  and accuracy (0x0902)
    • UUID (0x020106) +3 unknowns

    Still to find out:

    • uptime in seconds
    • rssi, txPower and temp scale
    • Lots of unknowns (0x801 and 0x020106)

    @Adrian Ziobro Has the specification for the Kontakt.io Telemetry packet been released yet?

  • Liam Relihan

    I need this information also. In particular I need brightness data


  • Fabian Ramirez

    there are news about the documentation release date? I need it urgently.

    At least, it would need confirmation that there will be no licensing problems for reverse engineering the information published by the beacons in this telemetry frame.

  • Morgan Heijdemann

    Placing the beacon (only) in Kontakt.io Telemetry packet greatly reduces battery life.
    All our Tag S18-3 (firmware v1.3) ran out of battery within 2 months.

    I wonder if the Power Saving based on working hours feature works independent of the Gateways or if it is a push from the gateways.

  • Morgan Heijdemann

    @Adrian Ziobro is been a year, hopefully a profitable one.
    Any luck opening up the tlm specs anytime soon?

  • Damian Kuźma

    Hi Morgan,

    The specs are already open and well documented. Please refer to our Developer Portal.
