C1-Public
Plug the external power supply to the power jack connector (J5), or connect a USB host to the USB
connector (J8) with a USB cable. Alternatively, you can power on a EVK-ANNA-B4 evaluation board
with a CR2032 coin cell battery. See also
Powering options
for more details.
Assigning COM ports
Two COM ports are automatically assigned to the device by Windows:
•
The COM port labelled “USB Serial Port” is used to communicate with the UART interface of the
ANNA-B4 module.
•
The COM port labelled “JLink CDC UART Port” can be used as an extra USB to the UART
interface. See also

EVK-ANNA-B412
3.2.1.1
u-connectXpress software
EVK-ANNA-B412 is equipped with ANNA-B412 module that runs the u-connectXpress software. The
software is preinstalled on the module.
☞
Go to the u-blox support webpage to obtain the latest available software. Instructions on
reflashing the EVK-ANNA-B4 can be found in the Software section of the ANNA-B4 system
integration manual [4].
3.2.1.2
s-center evaluation software
To communicate with the ANNA-B412 modules using AT commands, set the baud rate to 115200
with 8N1 flow control. See also
Quick start guide
.
All available AT commands are described in the u-connect AT commands manual [
6
].
To get started with the basic use-case setup of EVK-ANNA-B412 with u-connectXpress software, see
the user guide [

].
EVK-ANNA-B402
3.2.2.1
Nordic Semiconductor SDK
To use the EVK-ANNA-B402 together with Nordic Semiconductor SDK it is necessary to:
•
Create your own board file
•
Adapt the examples in the Nordic Semiconductor SDK to use this board file
For more information about performing these tasks, see also the Software section of the ANNA-B4
system integration manual [4]. See also the u-blox short range open CPU github repository [
