Device Profile
Usually device profiles are saved once during the production of the devices. E.g.
TCR-DLI
/LS/EU868
However starting with TCR GEN2 and Firmware V2.1, both the
Speed Class
as
well as the
LoRaWAN® Region
may be changed by the user too.
This allows to stock standard types (TCR-DLI, TCR-DLE, TCR-SLI, TCR-SLE) and
configure it later according to customers need.
Note: Device profiles can only be changed via the command line interface.
Changes will be stored in a secure element (a separate chip on the mainboard)
and will not be overwritten by Firmware Updates.
Changing Speed Class
Speed classes are used to better adapt the radar algorithm to the objects to be
measured.
Speed class 1 (low speed) is used for pedestrians and bicycles or very slow-
moving cars in parking areas. The typical range is about 1 to 40 km/h
Speed class 2 (high speed) goes up to 120km/h. However, slow objects (<
10km/h) such as pedestrians can no longer be detected reliably.
The boundaries are not absolute like nothing in this world is absolutely
deterministic. Changing radar scanning frequencies shift the detection
characteristic.
Important: An incorrectly selected speed class can strongly influence the
measurement results.
In order to change the speed class of your device use the following command
sequence in the CLI.
Set to low speed (LS)
