2.1 03925 Device Overview
The pushbutton transmitter module 03925 enables the implementation of wireless remote controls without batteries. It transmits
Bluetooth technology
Low Energy
(BLE) data telegrams where the required energy is provided by a built-in electro-dynamic energy generator.
The outer appearance of 03925 is shown in Figure 2 below.
2.2 Basic Functionality
03925 devices contain an electro-dynamic energy converter which is actuated by an energy bow (1). This bow is pushed by an appropriate push button, switch rocker
or a similar construction mounted onto the device. An internal spring will release the energy bow as soon as it is not pushed down anymore.
When the energy bow is pushed down, electrical energy is created and a BLE radio telegram is transmitted which identifies the action (pressed or not pressed) and the
status of the four button contacts (2). Releasing the energy bow similarly generates energy which is used to transmit a different radio telegram.
It is therefore possible to distinguish between radio telegrams sent when the energy bar was pushed and radio telegrams sent when the energy bar was released.
By identifying these different telegrams types and measuring the time between pushing and releasing of the energy bar, it is possible to distinguish between “Long” and
“Short” button contact presses. This enables simple implementation of applications such as dimming control or blinds control including slat action.
2.3 User Interface
03925 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.
Figure 3 below shows the arrangement of the four button contacts and their designation:
