5.2.2 Installing tag software on the command line with the DFU bootloader
To install C209 tag software with the pre-flashed DFU bootloader on NINA-B406:
1. Download and install the nrfutil flashing tool from the Nordic Github repository [15].
2. 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 from the main GitHub repository
page [12]. The unpacked file includes the NINA-B4-DF-TAG-SW-<version>.zip file used for the
installation, in one of the folders with “for_dfu_boot” in the name.
3. 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.
4. Use the following command to install the C209 tag software using nrfutil:
nrfutil dfu serial -pkg NINA-B4-DF-TAG-SW-<version>.zip -p COMXX -b 115200 -fc 1
☞ Replace COMXX with the appropriate COM port for your system and <version> with the current
version.
