Note 1.
0.5 byte is 4 bits. It is the time offset.
Refer to the description in the TOFF field.
Note 2.
115-6*16.5=16 bytes, 16 is not enough for one wristband information (16.5 bytes).
In cycle 1, Bluetooth Wristband has higher priority.
Note 3.
16 bytes are enough for one G-sensor tag message (15 bytes).
Note 4.
14.5*6+15=102 bytes. There are 115-102=13 left and it's not enough for one more
G-Sensor Bluetooth
tag message.
In cycle 2, G-Sensor Bluetooth tag has higher priority.
Note 5.
13-11=2 bytes. 13 bytes left is enough for one more light alarm Bluetooth tag message. The 2 bytes
left is not enough for any more messages.
Note 6.
4*10.5+1*11=53 bytes
In cycle 3, Light alarm Bluetooth tag has higher priority.
Note 7.
5.5*6=33 bytes
In cycle 3, Bluetooth Beacon message is sent after the light alarm Bluetooth tag.
Note 8.
115-53-33=29 bytes. It is enough for one Bluetooth Wristband message (17 bytes).
In cycle 4, Bluetooth Wristband is sent after Bluetooth beacon message.
Note 9.
29-17=12. It is not enough for one G-Sensor Bluetooth tag information.
The example below shows all 3 (Bluetooth Wristband) + 2 (G-Sensor Bluetooth tag) + 2 (Light alarm
Bluetooth tag) + 5 (Bluetooth Beacon) stay in the range of the GW all the time.
