PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

A.2 Configuration examples

This chapter provides examples of common NFC configuration tasks. These examples all

follow the same basic configuration sequence as discussed in Chapter 5.7.

A.2.1 Configuration sequence

This configuration sequence consists of the following steps:

1. Specify the request type and the request originator as defined in Table 27

2. Authenticate the configuration request

Provide the corresponding NFC PIN code as discussed in Chapter 5.1.2

3. Specify registers to be updated

Applies if configuration request type is “register update”. Register specification is

done by the CONFIGURATION_SELECTION register described in Chapter 5.7.3

4. Specify the content of the registers to be updated

Applies if configuration request type is “register update”.

Update values are provided in the corresponding register of the NEW CONFIGURA-

TION area as described in Chapter 5.7. Registers for which no update has been re-

quested can be written as 0x00; their content will not be changed.

5. Actuate the connected ECO 200 harvester five times in each direction to provide the

required energy for the configuration sequence

A.2.2 Request status

PTM 535BZ uses the REQUEST_STATUS register to inform the user about the status of a

configuration request in described in Chapter 5.6.17. This register should be consulted to

check if a configuration request was successful and to determine the root cause of a config-

uration request failure.

The REQUEST_STATUS register can be read as follows:

Command Description

SearchTag(32)

Connect to tag

(Search for up to 32 byte ID)

ISO15693_ReadSingleBlock(0x004D,0xFF)

Read REQUEST_STATUS

(Status is allocated in Byte 0 / MSB)

The first (most significant) byte that is returned by the NFC reader contains the configura-

tion request status.
