Software and flashing
C209 tags are delivered with bootloader software only and do not include the tag software (from
Github) 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 [11]
flashing tool is needed to install the open-source tag software (from Github). C209 tag software is
available from the u-blox open CPU repository [12].
Flash C209 using the following command:
☞
Replace
COMXX
with the appropriate COM port for your system.
nrfutil dfu serial -pkg app.zip -p COMXX -b 115200 -fc 1
The bootloader needs to be manually set in the software
“
upload
”
mode by pressing the SW2 button
(see Figure 13) on the C209 while resetting the board.
The C209 can also be flashed using a debugger, using the 10-pin debugger contact available on the
PCB.
