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.
For more information about the Bluetooth device address for NINA-B40x, see also Bluetooth device
(MAC) address and other production data.
