Although the sensors on the C209 application board are not used in the latest direction-finding
tag software from u-blox, the sensors can be utilized in any customer application.
4.2 Software and flashing
C209 tags are delivered with bootloader software only and do not include the tag software (available
from Github
[13]) needed for the device to advertise Bluetooth beacons to C211 anchor nodes.
The bootloader on C209 tags is different than that supplied on C211anchor nodes, and the nrfutil
[16] flashing tool is needed to install software over the UART interface with the boot loader.
