PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

3.3.5 Source address

The six-byte source address identifies the originator (sender) of BLE telegrams.

PTM 535BZ supports using either static source addresses or resolvable private addresses. By

default, PTM 535BZ uses static source addresses. PTM 535BZ can be configured to use re-

solvable private addresses as described in Chapter 5.6.4.

The type of address (static source address or resolvable private address) that is currently

used can be determined by the two most significant bits of the address; both address types

described in the following two chapters.

3.3.5.1 Static source address

Static source addresses are assigned during manufacturing and remain constant unless the

user configures a different source address via NFC.

Static source addresses are identified by the two most significant bits (Bit 47 and Bit 46 in

Figure 9) being set to 0b11.

The structure of PTM 535BZ static source addresses is as follows:

 The upper 2 bytes of the source address are used to identify the device type and set

to 0xE215 for all PTM 535BZ devices (to ensure telegram compatibility with EnOcean

PTM 535BZ devices).

 The lower 4 bytes start with 0x1, are uniquely assigned to each PTM 535BZ during

manufacturing and can be reconfigured via NFC as described in Chapter 5.6.6

PTM 535BZ static source addresses therefore have the format 0xE215:1xxx:yyyy. This enables

easy distinction (based on the static source address) between PTM 535BZ devices and PTM

215B devices (which use the static source address format 0xE215:0xxx:yyyy).

Figure 9 below illustrates the static address structure used by PTM 535BZ.
