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].

5.2.1 Installing tag software with the DFU bootloader using s-center
☞ Flashing the software over the UART interface requires s-center 6.1 or later.
To flash C209 tags over the UART using s-center [7].
1. Download and unpack the c209_aoa_tag_<version>.zip file from the u-blox C209 software
repository using this direct link, or go to the “Releases” section in the main GitHub repository
page [12]. The unpacked file includes the NINA-B4-DF-TAG-SW-<version>.zip file used for the
installation.
2. Press and hold the SW2 button on the C209 while resetting the board (by inserting the USB cable
or clicking the RESET button) to set the bootloader in “download” mode. See also Figure 24.
3. Open s-center on the correct COM port once the module is in the software download mode.
4. Select Software Update.
5. In the “Software Update” dialog, select the NINA-B4-DF-TAG-SW-<version>.zip file from the
software container, as shown in Figure 25. Make sure the flashing speed is set to 115200, and
that you select the zip from a folder with “for_dfu_boot” in the name.
6. Press Update.
