3.2.1.1
u-connectXpress software
EVK-NINA-B41x is equipped with a NINA-B41x 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-NINA-B4 can be found in the Software section of the NINA-B4 system
integration manual [4].
3.2.1.2
u-connectLocate software
EVK-NINA-B410DF is equipped with a NINA-B410-40B module that runs the u-connectLocate
software. The software needs to be downloaded to the module. Note that the NINA-B41x-40B
modules are not compatible with u-connectXpress software, only the u-connectLocate software.
☞
Go to the u-blox support webpage to obtain the latest available software. Instructions on
flashing the EVK-NINA-B410DF can be found in the Indoor direction finding XPLR-AOA explorer
kits User Guide [8].
EVK-NINA-B40x
3.2.2.1
Nordic Semiconductor SDK
To use the EVK-NINA-B40x 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 the Software section of the NINA-B4
system integration manual [4]. See also the u-blox short range open CPU github repository [9].
3.2.2.2
Software debug options
Use either of the following options to debug software with EVK-NINA-B4:
•
Onboard debug solution available through the USB connector
•
External debugger connected to J12 connector
An external debugger is useful when powering the evaluation board with a CR2032 coin cell battery,
or through the J5 external power supply connector. It is also useful when the MCU interface has been
disconnected from the NINA-B4 module using the jumpers on the J19 header.
SEGGER J-Link software [6] is necessary to debug with the onboard J-Link hardware on the EVK-
NINA-B4.
3.3
Measuring current consumption
☞
Before starting the current consumption measurement, go through Chapter 4 to identify your
chosen power configuration and find out what NINA signals must subsequently be isolated. The
J22 jumper pins 1 and 3 must be removed to measure the current consumption.
Figure 5 shows some suggestions for connecting the various instruments when measuring module
current consumption.
Using an ampere meter
An ampere meter should be connected in series with whatever the power source is and what is being
measured. In this way the current can be measured when the NINA module is supplied from either the
onboard 3.3 V regulator or an external supply.
