4.3 C211 anchor nodes
4.3.1 Overview
C211 application boards are equipped with a NINA-B411 module and an antenna array. These boards
fulfill the role of the anchor node in the XPLR-AOA direction-finding solutions. Anchor nodes run AT
command-based u-connectLocate direction finding software, which
delivers AoA data for tracked
tags to a listening host. Data is transmitted to the host as events over the NINA-B411 UART
interface. See also
Anchor node AT commands .
•
C211 has an array of five antennas that are used to detect the phase shift for the direction finding
– in both horizontal and vertical levels.
• C211 also has an LED array in the form of a cross. The LEDs indicate the direction of tracked
beacons. In instances where the anchor node tracks several beacons, the LED array tracks the
first C209 tag that is discovered.
☞
Some product variants do not include the LED cross on the C211 application board, which is part
of the XPLR-AOA kits:
o
XPLR-AOA-1-00 C211 has an active LED array
o
XPLR-AOA-1-01 C211 does not have an active LED array
o
XPLR-AOA-2-00 C211 has an active LED array
o
XPLR-AOA-2-01 C211 does not have an active LED array
