Timestamp Of The Frame - ADEUNIS LoRaWAN COMFORT CO2 Guide Utilisateur

LoRaWAN COMFORT CO2 - Guide utilisateur / User guide version V1.1.1
NOTE: it is possible to configure a threshold of event to detect before to send (S383).
Example:
Register Encoding
value
S382 Hexadecimal 0x41
FR
S383 Decimal
* Debounce time: minimum time to take account of a change of state. For example, if this period is 10 ms all pulses (high or low level) whose duration is less
than 10 ms will not be considered. This technique avoids potential rebounds during a change of state.

In this example, the device:
• detects high edges longer than 100 ms (register S382).
• send a frame after 5 detections of high edges respecting criteria (register S383).

2.11. Timestamp of the frame

The device can add a timestamp in the frame if the feature is activated.
The timestamp is given in EPOCH 2013. (Refer to the TRM of the device to know the content of the frame).
To activate the timestamp, open the IoT Configurator, go into the Applicative section and activate the Timestamp.
Then go to the Advanced mode and set the UTC time with the button "Set UTC time".
In option, and not recommended by adeunis, it is possible to set a local hour sent by the device.
To do it, configure the timezone where the device is installed and then select if the daylight management should be done automatically by the
device.
TO KNOW: most of the computing tools manage and convert UTC time, it is then advice to work with this universal time instead of using a
local time.
Value Result
Configuration of the digital input:
• Detection of high edges
• Debounce period of 100 ms
5 The device send a frame after 5
change of states on the digital input
