The UART connections on the ANT-Bxx and onboard NINA-B411 are connected to the MCU by default.
It is possible to connect directly from the USB connector to either:
•
NINA-B411 hosted on the ANT-Bxx board (with jumper J12 removed)
•
onboard NINA-B411 (with jumper J11 removed)
The connection options make it possible to perform software updates or configuration through the
UART interface. For jumper locations, see

4.5.1 Default software
The board comes flashed with example software that implements the
The software is developed using NXP's MCUXpresso Software and Tools and is available as an open-
source resource from the dedicated GitHub repository [19].
Follow the README file in the GitHub repository for further instructions.
4.5.2 Flashing
EVB-ANT-1 is normally flashed over the JTAG interface on the board. A debugger and a cable for the
19-pin JTAG interface is needed.
The code is stored on a NOR flash connected to the MCU.
It is also possible to use the Serial downloader over USB. This is done by changing the boot
configuration to start up in Serial downloader mode, see
4.5.3 Configuration interface
The default software on the EVB-ANT-1 enables the Anchor point. The network parameters can be
configured by using the web interface available on port 80 of each device, as shown in
