1.6.3 u-connectLocate software
u-connectLocate is direction finding software from u-blox. The software runs on all NINA-B41x
module variants that are enabled for Bluetooth Direction Finding. The ordering numbers for all module
variants equipped with this software end with the suffix -4xB. For example, NINA-B411-4xB. See also
the respective NINA data sheets
[2][3] .
☞
Modules enabled for direction finding cannot run regular u-connectXpress software.
Consequently, the flashing procedure is different from that of all other u-blox modules. See also
the XPLR-AOA explorer kits user guide
[23] .
1.7 Bluetooth device address
You can scan the data matrix barcode on the module label to retrieve the Bluetooth device address.

1.8 Pin configurations and functions
1.8.1 NINA-B40 pins
The pin functions of the versatile NINA-B40 open CPU should be selected with consideration to the
pin-out and nRF52833 multiplexing. The pin assignments for NINA-B40 are shown in
Figure 4 .

1.8.2 NINA-B41 pins
The u-connectXpress software running on NINA-B41 modules has fixed pin multiplexing that
implements a given set of features, like the UART connection. The pin assignments for NINA-B41 are
shown in
