Page 9: User Interface
PUSHBUTTON TRANSMITTER MODULE User Interface PTM 216B devices provide four button contacts. They are grouped into two channels (Channel A and Channel B) each containing two button contacts (State O and State I). The state of all four button contacts (pressed or not pressed) is transmitted together with a unique device identification (48 Bit device ID) whenever the energy bow is pushed or re- leased. -
Page 10: Telegram Transmission
PTM 216B transmits Bluetooth Low Energy (BLE) advertising telegrams within the 2.4 GHz radio frequency band (2402MHz … 2480MHz). By default, PTM 216B will use the three BLE advertising channels (BLE Channel 37, 38 and 39) defined for transmission. The transmission of a radio telegram on these three advertis- ing channels is called an Advertising Event. -
Page 11: Default Radio Transmission Sequence
In certain situations, it might be desirable to transmit radio telegrams on channels other than the three advertising channels. PTM 216B therefore allows to select the radio channels to be used for the transmission of data telegrams and commissioning telegrams. The following transmission modes are sup-... -
Page 12: Supported Radio Transmission Sequences
TX_CHANNEL1, TX_CHANNEL2 and TX_CHANNEL3. The PTM 216B telegram will in this mode be transmitted on the radio channel selected by TX_CHANNEL1 first, immediately followed by a transmission on the radio channel selected by TX_CHANNEL2 and a transmission on the radio channel selected by TX_CHANNEL3. -
Page 13: Two-Channel Radio Transmission Sequence
(selected by TX_CHANNEL2 and TX_CHANNEL3 respectively), i.e. all transmis- sions will be on the radio channel selected by TX_CHANNEL1. The PTM 216B telegram will be sent six times on this radio channel as shown in Figure 8 below. -
Page 14: Telegram Format
® PUSHBUTTON TRANSMITTER MODULE 4. Telegram format PTM 216B transmits Bluetooth Low Energy (BLE) radio telegrams in the 2.4 GHz band. For detailed information about the Bluetooth Low Energy standard, please refer to the applicable specifications. Figure 9 below summarizes the BLE frame structure. -
Page 15: Source Address
4.4.1 Static source address mode By default, PTM 216B uses static source addresses meaning that the source address is con- stant during normal operation. The static source address can be read and configured (written) via NFC as described in chapter 6. -
Page 16: Resolvable Private Address Mode
(sharing a specific security key with PTM 216B) to do so. The shared security key – which has to be known by both PTM 216B and the authorized receiver – is called the Identity Resolution Key (IRK). PTM 216B uses its device-unique ran- dom key as identity resolution key. -
Page 17: Check Sum
The 3 byte BLE Check Sum is used to verify data integrity of received BLE radio telegrams. It is calculated as CRC (cyclic redundancy check) of the BLE Header, Source Address and Payload fields. © 2023 EnOcean | www.enocean.com F-710-017, V1.0 PTM 216B User Manual | v1.0 | May 2023 | Page 17/49... -

Page 20: Commissioning Telegram Payload
The payload of commissioning telegrams is 30 bytes long and consists of the following fields: Length (1 byte) ◼ The Length field specifies the combined length of the following fields. For PTM 216B commissioning telegrams, this field is set to 0x1D to indicate 29 byte of manufac- turer-specific data. -
Page 21: Ptm 216B Data Telegram Authentication
In order to avoid message replay (capture and retransmission of a valid message), it is re- quired that the receiver tracks the value of the sequence counter used by PTM 216B and only accepts messages with higher sequence counter values (i.e. not accepts equal or lower sequence counter values for subsequent telegrams). -
Page 22: Authentication Implementation
® PUSHBUTTON TRANSMITTER MODULE 4.7.1 Authentication implementation PTM 216B implements data telegram authentication based on AES128 in CCM (Counter with CBC-MAC) mode as described in IETF RFC3610. At the time of writing, the RFC3610 stand- ard could be found here: https://www.ietf.org/rfc/rfc3610.txt... -
Page 23: Commissioning
The receiver needs to know how to uniquely identify this specific PTM 216B device. This is achieved by using a unique 48 Bit ID (Source Address) for each PTM 216B device as described in chapter 4.4. In addition, up to 4 byte of Optional Data can be configured via NFC configuration as described in chapter 6. -

PTM 216B configuration using the default PIN code. Should you lose the new NFC PIN code then PTM 216B can be reset to factory mode (with the default NFC PIN code) by means of a factory reset as described in chapter 5.4. -
Page 25: Camera-Based Commissioning
For cases where both NFC and camera-based commissioning are not feasible it is possible to set PTM 216B into a specific mode where it transmits commissioning telegrams. This functionality can be disabled via NFC configuration as described in chapter 6 or by means of a specific button press (long press of A0 + A1 + B1), see chapter 5.3.4. -
Page 26: Commissioning Telegram Transmission
PUSHBUTTON TRANSMITTER MODULE To enter commissioning mode, start by selecting one button contact of PTM 216B. Any button of PTM 216B (A0, A1, B0, B1) can be used. This button is referred to as Button_X in Figure 20 above. Next, execute the following long-short-long sequence: 1. -
Page 27: Factory Reset
PTM 216B can be reset to its default settings by means of a factory reset. This ensures that PTM 216B can be reset to a known configuration in case the PIN for the NFC access has been lost or NFC access is not possible for other reasons In order to execute such factory reset, the rocker(s) and the switch housing have to be re- moved from the PTM 216B module. -
Page 28: Nfc Interface
NFC interface parameters The NFC interface of PTM 216B uses NFC Forum Type 2 Tag functionality as specified in the ISO/IEC 14443 Part 2 and 3 standards. For a detailed description about the NFC functional- ity, please refer to the ISO/IEC 14443 standard. -
Page 29: Pc With Dedicated Nfc Reader
NFC functionality is available in certain Android (e.g. Samsung Galaxy S7 or newer) and iOS (iPhone7 or newer, firmware version 13 or newer) smartphones. EnOcean provides the configuration app “EnOcean Tool” for these devices which can be downloaded directly from the respective app store. -
