sigfox RC4 Pulse - Guide utilisateur / User guide version V1.0.0
In the example in grey this gives:
•
Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 3 (fourth frame)
•
Bytes 3 to 4 : Delta A4 : index variation of channel A during the time interval between 50 to 60 minutes after transmitting the previous
frame = 0x074A so 1866 additional pulses
•
Bytes 5 to 6 : Delta B4 : index variation of channel B during the time interval between 50 to 60 minutes after transmitting the previous
frame = 0x003B so 59 additional pulses
4.1.9 Periodic frame with 24 hours-history

Description of the frame :
•
Byte 2: frame index: index of this frame in a multi-message sequence.
•
Bytes 3 to 6 : Counter - channel A : counter value of channel A 1 hour after transmitting the previous frame.
•
Bytes 7 to 10 : Counter - channel B : counter value of channel B 1 hour after transmitting the previous frame.
In the example in grey this gives:
•
Byte 2: frame index: index of this frame in a multi-message sequence (here set to 0 for the first frame) = 0
•
Bytes 3 to 6 : Counter - channel A : counter value of channel A 10 minutes after transmitting the previous frame = 0x00015C4F so 89,167
pulses
•
Bytes 7 to 10 : Counter - channel B : counter value of channel B 10 minutes after transmitting the previous frame = 0x0000F74A so
63,306 pulses

Description of the frame :
•
Byte 2: frame index: index of this frame in a multi-message sequence.
•
Bytes 3 to 4 : Delta A0 : index variation of channel A during the time interval between 1 to 2 hours after transmitting the previous frame.
•
Bytes 5 to 6 : Delta B0 : index variation of channel B during the time interval between 1 to 2 hours after transmitting the previous frame.
•
Bytes 7 to 8 : Delta A1 : index variation of channel A during the time interval between 2 to 3 hours after transmitting the previous frame.
•
Bytes 9 to 10 : Delta B1 : index variation of channel B during the time interval between 2 to 3 hours after transmitting the previous frame.
In the example in grey this gives:
•
Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 1 (second frame)
•
Bytes 3 to 4 : Delta A0 : index variation of channel A during the time interval between 1 to 2 hours after transmitting the previous frame =
0x0012 so 18 additional pulses
•
Bytes 5 to 6 : Delta B0 : index variation of channel B during the time interval between 1 to 2 hours after transmitting the previous frame =
0x0020 so 32 additional pulses
•
Bytes 7 to 8 : Delta A1 : index variation of channel A during the time interval between 2 to 3 hours after transmitting the previous frame =
0x0007 so 7 additional pulses
•
Bytes 9 to 10 : Delta B1 : index variation of channel B during the time interval between 2 to 3 hours after transmitting the previous frame
= 0x0010 so 16 additional pulses
