USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.4 User Interface PTM 215B 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 released.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.5 PTM 215B radio channel parameters PTM 215B transmits advertising telegrams within the 2.4 GHz radio frequency band (2402MHz … 2482MHz) using the BLE advertising frame format. By default, PTM 215B will use the three BLE advertising channels (Channel 37, 38 and 39) defined for transmission. Table 1 below summarizes the radio channel assignment within the BLE standard.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.6 PTM 215B button action encoding Figure 6 below shows the button action encoding used by PTM 215B. In PTM 215B, the type of action (Press Action or Release Action) is indicated by Bit 0 (Energy Bar). If a button contact has been actuated during Press Action or Release Action then this is indicated by the according status bit set to ‘1’. Note that all contacts that were pressed during Press Action will be released during Release Action.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.7 PTM 215B commissioning Commissioning is the process by which PTM 215B is learned into a receiver (actuator, controller, gateway, etc.). The following two tasks are required in this process: n Device identification The receiver needs to know how to uniquely identify this specific PTM 215B device. This is achieved by using a unique 48 Bit ID (Source Address) for each PTM 215B device as described in chapter 2.9.4.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.8 Operation modes PTM 215B can operate in two modes: n Data mode Data mode is used to transmit data telegrams reporting the status of PTM 215B button inputs n Radio-based commissioning mode Radio-based commissioning mode is used to commission (teach-in) PTM 215B into a specific receiver or network by means of a specific commissioning telegram. This is an alternative for scenarios where NFC commissioning cannot be used. 2.8.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.8.2 Radio-based commissioning mode Radio-based commissioning mode is used to associate PTM 215B with other devices. To do so, PTM 215B can transmit a dedicated commissioning telegram (as described in chapter 2.9.6.2) identifying its relevant parameters.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.8.2.2 Commissioning telegram transmission PTM 215B will transmit a commissioning telegram (as sequence of Advertising Events on the BLE advertising channels as described in chapter 2.5) upon entering commissioning mode. The format of the commissioning telegram is described in chapter 2.9.6.2.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.9 BLE frame structure PTM 215B transmits radio telegrams in the 2.4 GHz band according to BLE frame structure. For detailed information about the BLE standard, please refer to the applicable specifications. Figure 8 below summarizes the BLE frame structure. Figure 8 – BLE frame structure The content of these fields is described in more detail below. 2.9.1 Preamble The BLE Preamble is 1 byte long and identifies the start of the BLE frame.
USER MANUAL 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.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module 2.9.4.2 Private resolvable source address mode For some applications it is desirable to modify (rotate) the source address used by PTM 215B in order to prevent tracking of its radio transmissions. At the same time, each PTM 215B device must remain uniquely identifiable by the receiver. To achieve these goals, PTM 215B can be configured via NFC to use random resolvable private addresses.
USER MANUAL PTM 215B – 2.4 GHZ Pusbutton Transmitter Module The receiving device maintains a list of IRK for all transmitters that have been commissioned to work with it. Whenever the receiving device receives a radio telegram with private resolvable source address (identified by the most significant bits being set to 0b10), it will itself generate a 24 bit hash from the 24 bit prand sequentially using the IRK of each device that it has been learned into it. If an IRK matches (i.e.
