PTM 215B – 2.4 GHZ Pusbutton Transmitter Module

2.9.4 Source address

The 6 byte BLE Source Address (MAC address) uniquely identifies each PTM 215B product.

PTM 215B supports two source address modes:

n Static Source Address mode (default)

In this mode, the source address is constant (but can be configured via NFC interface)

n Private Resolvable Address mode (NFC configurable)

In this mode, the source address changes for each transmission

PTM 215B uses by default the Static Source Address mode. The Private Resolvable Address

mode can be selected by setting the Private Source Address flag in the Configuration regis-

ter (see chapter 2.11.4.2) to 0b0.

These two address modes are described in the following chapters.

2.9.4.1 Static source address mode

By default, PTM 215B uses static source addresses meaning that the source address is con-

stant during normal operation. The static source address can be read and configured (writ-

ten) via NFC as described in chapter 2.11.

The structure of PTM 215B static addresses is as follows:

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

0xE215 for all PTM 215B devices (to designate EnOcean PTM 215 device type).

n The lower 4 bytes are uniquely assigned to each device.

Figure 10 below illustrates the static address structure used by PTM 215B.
