CheckFox log data interpretation

How to interpret the data the CheckFox log?

Example: Following data is uploaded to the dashboard shortly after the Sigfox message is transmitted from the device.


Each value is separated by a comma (“,”).
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
For parsing of the last letters - ABCDEFGH - see the table below.

*Accelerometer data can be used to determine unwanted movement during Sigfox transmission (which can negatively affect the RF performance).

arsing the last 4 bytes (8 letters - ABCDEFGH) of the payload:

A (Main menu selection) 1 Outdoor above 1m
2 Outdoor 1m reference
3 Outdoor 0m ground level
4 Indoor
5 Deep indoor
B (Measurement type) 1 Survey 1x immediately
2 Survey 1x delayed
3 Final 6x immediately
4 Final 6x delayed
5 Downlink test
6 Periodic measurement 1min + GPS
7 Periodic measurement 10min + GPS
8 Periodic measurement 60min + GPS
9 Periodic measurement 10min no GPS
A Periodic measurement 60min no GPS
B Audit 100x immediately
C Audit 100x delayed
CD (Messages) 0x01-0xFF Number of messages sent in the present test batch
EF (Sequence number) 0x01-0xFF Actual message counter (sequence number)
GH (reserved) N/A N/A
