The state object

The gateway keeps its own state and that of its sensors in a single object, delivered by stateupdate and kept current by statepatch.

{
  "nodes": {},
  "deviceInfo": {},
  "phantomSync": [],
  "basicconfig": {}
}

Property	Contains
`nodes`	Every sensor the gateway is seeing, or has seen, keyed by serial number
`deviceInfo`	Running state of the gateway itself
`phantomSync`	Array of PHANTOM® Sync groups
`basicconfig`	Gateway configuration

`nodes`

Keyed by sensor serial number. A vibration sensor looks like this:

{

      "range": 8,
      "recordingSettings": 0,
      "seq": 1
    }
  }
}

Property	Meaning
`phantomCode`	Sensor serial number

`version`	Firmware version
`rssi`	Signal strength
`lastseen`	Milliseconds since 1970, gateway clock, when the sensor was last seen by the gateway’s Bluetooth radio
`lastseqchange`	Milliseconds since 1970, gateway clock, when the sensor’s `seq` last changed — i.e. when the gateway last got new data from it
`advdatav2`	The sensor’s advertised measurements and settings
`isPaired`, `isFavorite`, `isDFUmode`, `hasupdate`	Sensor flags
`lastcollection`, `lastManualCollection`	When a waveform was last collected
