Overview 

The ANT-B10 is a versatile Bluetooth direction finding board equipped with eight dual-polarized, patch 
antennas for direction finding, as shown i

Figure 1

. 

 

Figure 1: ANT-B10 board showing antennas and mounting holes 

The  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 MCU in  the 
module. The angles are delivered over the UART port of the ANT-B10. Future u-connectLocate SW 
versions may also include support for USB and SPI interfaces. 

For general information about Bluetooth direction finding, watch the u-blox webinars 

[2]

 and study 

the technical overview from the Bluetooth SIG

Suggested accessories 

The ANT-B10 board has a pin header used for the communication with a host PC. For initial testing, it 
is  advisable  to  use  this  header  to  set  up  a  UART  connection  to  the  PC.  See  also
