ANT-B10 board hosts a single NINA-B411-40B Bluetooth Low Energy (LE) module, which controls the
antennas and applies an angle calculation algorithm to the received signals to compute tag angles.
The angles are calculated by the u-connectLocate software running on the embedded Microcontroller
Unit (MCU) in the module. The angles are delivered over the UART port of the ANT-B10. Future u-
connectLocate software releases can also include support for USB and SPI interfaces.
For general information about Bluetooth direction finding, watch the u-blox webinars [2] and study
the Bluetooth SIG technical overview [3] .
XPLR-AOA-3 contains the ANT-B10 board as well as an EVB-ANT-1 host board to facilitate
convenient testing.

3.1 Flashing ANT-B10 software
3.1.1 General
The u-connectLocate software is flashed using s-center or flashed directly on the command line.
To flash the software, the UART must be connected to the ANT-B10 board during the kit assembly
(see
UART connections to board) or connected directly to a PC (see Connecting to a PC) .
For software updates and further information about the software, see the u-connectLocate product
page
[10] and u-connectLocate AT commands manual [18] .
3.1.2 Flashing using s-center
ANT-B10 can be flashed over the UART using s-center [7] .
☞
Flashing over the UART requires s-center 6.1 or later.
Use the following procedure to flash ANT-B10 using s-center:
1.
Download and unzip the u-connectLocate software container, as described in Command line
flashing .
2. Open s-center on the correct COM port.
3. Select Software Update .
4. In the “Software Update” dialog , select the binary file in the software container, as shown in
Figure 6 . Make sure the flashing speed is set to 115200.
5. Press Update .
