PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

3.1 Radio parameters

PTM 535BZ transmits Bluetooth Low Energy (BLE) advertising telegrams within the 2.4 GHz

radio frequency band (2402MHz … 2480MHz) as defined in [2].

3.1.1 Bit rate

By default, PTM 535BZ uses a bit rate of 1 Mbit/s as defined in [2]. PTM 535BZ also sup-

ports a custom bit rate of 2 Mbit/s which can be selected via the NFC interface as described

in Chapter 5.6.3. Note that the 2 Mbit/s bit rate uses custom radio settings and is intended

for use only with certain partner applications.

3.1.2 Radio channels

By default, PTM 535BZ will use the three BLE advertising channels (BLE Channel 37, 38 and

39) defined for transmission. Use of different radio channels within the frequency band

from 2402 MHz to 2480 MHz can be configured using the NFC configuration interface as de-

scribed in Chapter 5.6.3 and Chapter 5.6.7.

Table 1 below summarizes the supported radio channels that can be selected via the NFC

configuration interface.
