I would like to know What is the limit on the number of ble devices that can be tracked concurrently by one Nrf52833 acting as an AoA device?.
Is there any reference antenna design as well as sample code for AoA location code?.

There is no hard limit - if you put CTE into an advertising packet, upon increasing a number of concurrent devices there will be issues with collisions that's hard to resolve (unlike payload data, CTE cannot be verified with a checksum). If you're planning to use connected mode, you're limited with 20 simultaneously connected devices - no collisions would occur, but unfortunately there's still no support for AoA in SoftDevice. If you choose to create your own protocol, you really have no limitations - for example, with 250-usec packet length and 1-sec interval, you can track about 3000 devices.
Thank you for the prompt reply. Is there an estimated/ballpark date as to the release of AoA in SoftDevice ?
