0x2F2F Always 0x2F2F (for decryption check)
0x00 Indefinite, variable value number
0xFD Second extension of VIF
0x3A Dimensionless/no VIF
0x06 Unsigned 24 bit data
0x000E10 Log data rate = 3,600 s
0xB5 New log - increase incrementally upon each new frame
0x000015 Time between the last saved data and sending of the log/
history = 21 s
0x00 Number of the frame to come
0x02
0x063CCE ADC or On-Off value sampled 21 s ago
0x04196B ADC or On-Off value sampled 21 s ago + 3600 sec
BF RSSI of the frame received: RSSI value = -125 + (x *
0.5), namely, in this example BF = 191, RSSI = -125 +
(191*0.5) = -29.5 dBm
