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
| 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).
