The following example is 0x35 atmospheric pressure of GlobalCalibrateCmd.
(1)
If the R720C detects is 1000 hPa and the actual atmospheric pressure is 999 hPa, it means the calibration we want to make is
-1hPa.
Configure R720C device parameter Channel = 01
、
Multiplier = 000A
、
Divisor = 0000
、
DeltValue = FFFF(-1)
(The calibration data is 000A*FFFF = -10)
Downlink:
013501000A0000FFFF0000
Device return:
Uplink: 8135010000000000000000 (configuration success)
Uplink: 8135010100000000000000 (configuration failure)
