PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

4.2 Radio transmission sequence

PTM 535BZ transmits ZGP data telegrams as a set of redundant transmissions where the

same data telegram is transmitted 3 times. The timing interval between the start of two

consecutive redundant data telegrams is approximately 2.5 ms and varies by some random

timing offset.

Figure 20 below shows the ZGP radio transmission sequence used by PTM 535BZ for data

telegrams.

PTM 535BZ transmits ZGP commissioning telegrams (which are much longer than ZGP data

telegrams) as a set of redundant transmissions where the same data telegram is transmitted

2 times. The timing interval between the start of the two consecutive redundant commission-

ing telegrams is approximately 2.5 ms and varies by some random timing offset.

Figure 21 below shows the ZGP radio transmission sequence used by PTM 535BZ for com-

missioning telegrams.
