5.2 C209 Software and flashing
C209 tags are delivered with bootloader software only and do not include the tag software (available
from Github
[12]) needed for the device to advertise Bluetooth beacons to anchor nodes.
The bootloader on C209 tags is different than that supplied on anchor nodes, and the nrfutil [15]
flashing tool is needed to install software over the UART interface with the boot loader.
u-blox C209 tag software can be installed using the DFU bootloader or an external debugger.
Precompiled packages for each installation option are available from the u-blox C209 software
repository
[12] .
