2. WORK PRINCIPLE OF THE DEVICE
LoRa (from "long range") is a physical proprietary radio communication technique. It is
based on spread spectrum modulation techniques derived from chirp spread spectrum
(CSS) technology. In other words, small number of bytes over long range transmission.
Excitation of the device is done by pressing any of the buttons (depending on the version,
whether it is a device with 1, 2, 4 or 6 buttons). After pressing the button, the device loads all
the settings related to that button and controls the paired devices, if paired with one, but in
general it broadcasts the button ID. Each of the keys has its own unique ID number whose
values are given below:
•
•
•
•
•
•
Button 1 → ID = 0
Button 2 → ID = 1
Button 3 → ID = 2
Button 4 → ID = 3
Button 5 → ID = 4
Button 6 → ID = 5
By pressing any of the buttons, the command is transmitted to the paired devices via the
LoRa interface.
2.1 Sending a request for registration/deregistration
As already mentioned, in order to effectively use the device, it must be registered to at
least one of our other devices from the allowed group of devices. In order to register the
device, it is necessary to do the following procedure (valid for all hardware versions of the
device):
•
•
Press button 1 and hold it for a minimum of 3 and maximum of 5 seconds
After a proper button press, the device sends a registration request, after which
it should receive a response from the device that received the request
If the answer is confirmative, the device is paired, and it is possible to start the
button pairing process (if necessary)
•
•
A certain type of signaling is proof of the validity of a successful registration
The process of sending deregistration request is similar and consists of the following:
Press button 1 and hold it for a minimum of 6 and maximum of 10 seconds
