Any info or reference guides on hardware required for Bluetooth 5.1 Direction Finding/Location Services w/nRF52811?

[jdsmith99]

In addition to (obviously!) a 52811 chip and a BLE beacon, what additional hardware would one need for reasonably accurate location tracking of a BLE tag/beacon? I'm generally familiar with trilateration setups but not as familiar with how location tracking would work w/Bluetooh 5.1. Is it multiple beacons? Multiple RF52811 chips? The papers I've read talk about antenna arrays...in AoA, the receiver has an antenna array; in AoD, the transmitter has an array. Will nRF52811 boards have antenna arrays? Or will you build your own arrays using multiple nRF52811 chips? 

Thanks!

In case you have't already seen this: https://blog.nordicsemi.com/getconnected/bluetooth-5.1-puts-bluetooth-in-its-place and the nRF52811 product specification

Depending on the use case, AoA or AoD, external RF switches is needed to switch between two or more antennas. We will publish more about this as soon as the stack supports this feature.

Thanks! And thanks for the links. I'll keep an eye out.

Any update regarding the SDK support for direction finding feature using AOA or, AOD with antenna array?
