CheckFox Log Data Interpretation
Example
The following data is uploaded to the dashboard shortly after the Sigfox message is transmitted from the device. Each value is separated by a comma (“,”): LOGdata-02:0A04,08.04.2018,11:13:55,N50d00.5113,E014d43.5021,0,050,00405,360,100,808040,808040,4,4.0,22,ABCDEFGH
Example data parsing
0A04
Message sequence number (0-65535)
08.04.2018
Date (day.month.year)
11:13:55
Time (hours:minutes:seconds)
N50d00.5113
Latitude (where N=North, S=South, d=degree and 00.5113 are the minutes)
E014d43.5021
Longitude (where E=East, W=West, d=degree and 43.5021 are the minutes)
0
GPS fix (boolean, 1 means that a valid realtime GPS position was acquired)
050
Speed in km/h
00405
Altitude in meters over WGS84 Earth approximation model
360
Course (azimuth of movement acquired from the GPS receiver)
100
Horizontal dilution of precision
808040*
Minimal value from the accelerometer at the time of Sigfox transmission
808040*
Maximal value from the accelerometer at the time of Sigfox transmission
4
GSM signal strength (0-5, 0 means no GSM connection)
4.0
Battery voltage (proper operating range is from 3.6V to 4.3V)
22
Temperature measured internally by a sensor
ABCDEFGH
See the parsing for these letters below
*Accelerometer data can be used to determine unwanted movement during Sigfox transmission (which can negatively affect the RF performance).
