Following data (example) are uploaded to Checkfox Dashboard just after Sigfox test message has been transmitted.
Each value is separated by “,” (comma character).
Data parsing follows (example + explanation):
0A04 - seqence 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 minutes)
E014d43.5021 - longitude (where E=East / W=West, d=degree and 43.5021 are minutes)
0 - GPS fix (0 = no fix, 1=fix => valid realtime GPS position is acquired)
050 - speed in km/h (kilometers per hour)
00405 - altitude in meters over WGS84 Earth approximation model
360 - course (azimuth of movement acquired from GPS receiver)
100 - horizontal dilution of precision
808040 - minimal value from accelerometer during Sigfox transmission
808040 - maximum value from accelerometer during Sigfox transmission
4 - GSM signal strength (0 = no GSM signal, 5 = maximum GSM signal strength)
4.0 - Checkfox battery voltage (3.6V to 4.3V is proper operating range)
22 - temperature measured by Checkfox device (internal sensor data)
ABCDEFGH - see below:
<position AB> Byte (hexadecimal expression):
Upper 4 bits <position A> are “main menu selection” identifier:
1h = Outdoor above 1m
2h = Outdoor 1m refer.
3h = Outdoor 0m ground
4h = Indoor
5h = Deep Indoor
Lower 4 bits <position B> are “measurement type” identifier:
1h = Survey 1x immediately
2h = Survey 1x delayed
3h = Final 6x immediately
4h = Final 6x delayed
5h = Downlink test
6h = Periodic measurement 1min + GPS
7h = Periodic measurement 10min + GPS
8h = Periodic measurement 60min + GPS
9h = Periodic measurement 10min no GPS
Ah = Periodic measurement 60min no GPS
Bh = Audit 100x immediately
Ch = Audit 100x delayed
<position CD> Byte (hexadecimal expression):
Number (1-255) of messages being sent in present test batch.
<position EF> Byte (hexadecimal expression):
Actual message counter (1-255) = sequence number of message in present test batch.
<position GH> Byte (hexadecimal expression):
Reserved for future use.
Accelerometer data can be used to determine unwanted movement during Sigfox transmission (which can negatively affect the RF performance).
