System setup
4.1
Anchor node configuration
By default, the C211 Anchor Point comes pre-configured to track all u-blox tags. The u-blox tags
advertise with the Eddystone namespace
0x4E494E412D4234544147
,
which is default on the C211 to
track. So, if you are only using the u-blox supplied XPLR-AOA kit, 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=
2,2,”
6E616D65737061636578
”
At+UDFFILT=1,2,“
CCF9578E0D8A
”
,
”
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
Configuration direction fUDFCFG
The settings shall be saved using the
AT&W
command, followed by a restart (
AT+CPWROFF
).

Configuring advertising interval
Press the SW2 button on the C209 to change the advertising interval. The default interval at startup
is 20 milliseconds
When SW2 is pressed, the advertising interval cycles through [20, 100, 1000] milliseconds. For best
performance, it is advisable to use the default 20 ms advertising interval.
