Parameters description:
1. Connection type ( conntype )
Used for setting the device in ABP – value “1” or OTAA – value “0” mode.
2. Predefined addresses and keys ( deveui, appkeyota , keyotaa , addrabp , nwkskey , appskey )
These parameters are generated using multiple IDs specific to the particular MCU and are
unique for each device. They can be changed if needed.
3. Interval advertising Bluetooth ( advble )
Determines the interval of sending broadcast packets, used to connect to every BLE receiver
around the device.
4. Measuring threshold ( measlevel )
YO Analog is checking for changes in signal every 0,5 s . If consecutive measurement readings
differ by more than specified by this parameter (see equation below) the present value and
timestamp will be saved and prepared for transmission to the server (see figure 4).
𝑎 − 𝑏 | | > 𝑏 · 𝑡ℎ
where:
a – current measurement
b – immediately preceding measurement
th – threshold value [%]
5. Measuring and/or sending interval in seconds ( measinter )
Interval of sending each LoRa payload (t
li
on figure 4). It can be dynamically changed due to
the amount of peaks in the buffer (threshold exceed) in order to keep the server updated
with the latest data. For example if a payload can hold 4 points and we have 6 points to send
the algorithm will send these 4 points first and reduce the time interval of future payloads
(see figure 4).
6. Analog inputs ( input1, …, input6 )
You can set the device inputs to work in 2 modes:
●
value “1” – 4–20 mA current standard
●
value “2” – 0–10 V voltage standard
