PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

3 Bluetooth Low Energy (BLE) radio

By default, PTM 535BZ is configured to transmit BLE telegrams. The format of these tele-

grams is the similar to the format used by PTM 215B. Refer to [2] for a detailed description

of the BLE telegram format.

PTM 535BZ can transmit two types of BLE telegrams:

 Data telegrams

Data telegrams report the button status of PTM 535BZ

 Commissioning telegrams

Commissioning telegrams provide PTM 535BZ device parameters necessary for the

receiver to interpret and authenticate data telegrams

PTM 535BZ transmits BLE commissioning telegrams if the ECO 200 harvester is actuated and

either the LRN button is pressed or transmission of a commissioning telegram has been re-

quested via the NFC interface.

If the LRN button remains pressed, then commissioning telegrams will be transmitted when-

ever the same ECO action (press or release) is executed as when the LRN button became

pressed and ECO 200 was actuated. For the other direction (release or press), no telegram

will be transmitted.

If for instance the LRN button is pressed by the user and ECO 200 is then actuated into

“press” direction, then PTM 535BZ will transmit commissioning telegrams as long as the LRN

button remains pressed and ECO 200 is moved into the press direction. No telegrams will be

transmitted as long as the LRN button remains pressed and ECO 200 is moved into the re-

lease direction.

If transmission of a commissioning telegram is requested via NFC as described in Chapter

5.1.4.1, then PTM 535BZ will transmit a commissioning telegram upon the next actuation

(either press or release) of the ECO 200 harvester. After that, the request to transmit a

commissioning telegram will be cleared.

If the LRN button is not pressed when ECO 200 is actuated and no transmission of a com-

missioning telegram is requested via the NFC interface, then PTM 535BZ transmits data tel-

egrams if the ECO 200 harvester is actuated.

Data and commissioning telegrams share the same high-level telegram format and differ only

in the payload as described in subsequent chapters.
