Better location tracking for Bluetooth 5.1

Bluetooth 5.1 includes facilities for tracking the angle of Bluetooth transmitters with MIMO in actionrespect to the Bluetooth receiver with a high degree of accuracy. In Angle of Arrival scenarios, the technique uses multiple antennas at the receiving end and a special software algorithm to compute the arrival angle. In Angle of Departure situations, the transmitter has multiple antennas which send signals to a receiver with a single antenna. Dialog showed its dev kit for AoA and AoD work, visible here. This version has four antennas (more antennas, higher angle resolution), which can be seen on the right-hand side of the PCB. The Bluetooth chip, DA1469x, uses an external RF switch to make connections to the four antennas.
