Hi, in this tutorial we are going to talk about tag features.
These features might be set via wireless configuration through RTLS manager or via USB cable and
apropriate console.
Wireless configuration is described in Tag configuration video lesson.
First and most basic feature is tag's refresh rate.
As you can see the lower the refresh rate is, the faster the tag sends blinks to the
anchors and it's positions are faster calculated.
Refresh rate is set differently for different use cases.
In sport applications the refresh rate is set under 100 miliseconds.
On the other hand in simple presence detection the refresh rate might be set to 10 seconds.
Refresh rate has significant impact on tag's battery consumption.
Next useful feature is sleep mode.
This feature is great for saving battery when the tag is not moving around.
There are 4 different sleep modes.
First one is disabled which means the tag keeps sending positions even when the tag
is not moving.
Second one is sleep immediately.
This means as soon as the tag stops moving the sending stops as well.
It's the most basic sleep mode usage.
Next one is delayed sleep.
If this setting is active the tag enters sleep mode after 5 seconds from stopping.
This is good for making sure the position of the sleeping tag is accurate.
The last one is keep alive.
Tag will go to sleep mode immediately but keeps sending information every 5 seconds.
This is useful for keeping track of tags not moving around.
Sleep modes goes hand in hand with sleep threshold.
This metric tells us how much has the tag accelerate to be woken up from sleep mode
and kept alive.
As you can see the values differ for different tags.
Use the predefined values or feel free to experiment.
Random deviation is in this video only for a demonstration of what it does.
It should be always kept on, because it lowers the stress put on the network and server.
As you know there are two states of tag.
One when it is receiving data and one when it is sending them.
Recieving data is very battery consuming and can be done only a few times on piccolino
tags.
IMU tags might be in recieving state much more often.
Recieving state is the only state in which the tag can accept new configuration from
the anchors.
So if you don't want the need of restarting tag for it's reconfiguration or if you don't
have direct access to tags, you can use periodical Rx.
This feature puts tags into receiving state even without need of restarting it.
Don't set the value for periodical Rx too low, because it will drain your battery very
fast.
Rx duration tells the tag how long should it stay in receiving state once it is in there.
Reasonable values for Rx duration are around 200 miliseconds, because if the anchor is
sending configuration, it sends it every 50 miliseconds, so there is a pretty big chance
of catching the data.
Stay tuned and thanks for watching.
