6 u-connectLocate software
6.1 General information
u-connectLocate software can track a certain number of tags and report their angles in
+UUDF
events
over the UART connection. The software employs an algorithm to detect the direction or angle of a
moving tag.
As the antenna array on the board detects the Constant Tone Extension (CTE) advertised in a tag
beacon, the algorithm calculates the angles of the tag in two dimensions. The software runs on the
NINA-B411-40B module, which is connected to the antenna array and Bluetooth receiver on the
ANT-B10 board.
6.2 Configuration example
By default, u-connectLocate comes pre-configured to track all u-blox tags. The tags advertise with
the Eddystone namespace
0x4E494E412D4234544147
,
which by default is tracked in u-connectLocate.
So, if you are only using the u-blox C209 tags, no configuration is needed.
Each anchor node can be configured with beacons to track. An example for how to set up the anchor
to track two tags is shown below:
AT+UDFFILT=1,2,”6E616D65737061636578”
AT+UDFFILT=2,2, ” CCF9578E0D8A ”
AT+UDFFILT=2,2, ” CCF9578E0D8B ”
AT+UDFENABLE=1
(Tracking is enabled by default, so this is optional)
These commands set up the anchor to track the two tags with the given MAC addresses in the
Eddystone name space (
6E616D65737061636578
) used by the tags.
The sequence described above reflects the most simplistic use case. Further configuration is possible
using the
AT+UDFCFG
command. See also .
The settings shall be saved using the
AT&W
command, followed by a restart (
AT+CPWROFF
).
