4 XPLR-AOA anchor nodes and tags
4.1 Introduction
Both XPLR-AOA-1 and XPLR-AOA-2 explorer kits include both Bluetooth anchor nodes and tags.
☞
Although this chapter generally describes these nodes and tags in the context of the XPLR-AOA-1
direction finding system, the concepts it describes are equally applicable to the XPLR-AOA-2
indoor positioning explorer kit. For information about the XPLR-AOA-2 positioning engine, setup,
and configuration, see also the indoor positioning application note
[2] .
4.2 Overview
u-blox direction finding solutions are comprised of C211 anchor nodes C209 tags, as shown in
Figure 6 . See also Kit includes . u-blox direction-finding solution supports the Angle of Arrival (AoA)
methodology.
C211 anchor nodes are based on NINA-B4 modules that include support for direction finding.
Anchor nodes are based on NINA-B411 u-connectXpress functionality, whereas C209 tags are based
on NINA-B406 open CPU architecture. For more information about these short-range Bluetooth
modules, see also the respective data sheets
[14][15] and product pages [2] .
Figure 6 shows several anchor nodes and a host that uses the combined information from the anchor
nodes to calculate the position of the tag. For simple direction finding one anchor node is sufficient.
