4.4 C209 tags
4.4.1 Overview
☞
C209 is an example implementation of a tag and is not optimized or available as a separate
product.
C209 tags are based on the open CPU NINA-B406 module variant. The tags run on custom tag
software that advertises as an Eddystone beacon using extended advertising and using periodic
advertising with a Constant Tone Extension added to the periodic advertising packets. This CTE is
used by the u-connectLocate direction finding software that runs on the C211 application board to
calculate the Angle of Arrival.
The namespace included in the transmitted Eddystone-UID beacon is
0x4E494E412D4234544147
and
the instance id is based on the MAC address of the NINA-B406 found on the module QR code label.

C209 tags are powered by a single CR2032 battery (not included) or through the USB connector.
C209 tags includes a versatile sensor node that comprises several sensors for use in a multitude of
different applications. The on-board sensors include:
•
LIS2DW12 accelerometer
• APDS-9306 ambient light sensor
• BME280 humidity, pressure, and temperature sensor
