Here on the DevZone we never discuss or speculate in upcoming releases, so you will have to contact the Regional Sales Manager (RSM) of your area for details or a roadmap on when this might be available. If you don't know who this is or lack their contact information, please tell me where you're located and I will help you get in touch, or you can fill out our Sales Related Questions form here in order to get in touch.

Best regards,

Simon

Thank you for the prompt reply. Is there an estimated/ballpark date as to the release of AoA in SoftDevice ?

Hi,

[quote userid="20967" url="~/f/nordic-q-a/61721/nrf52833-location-finding-concurrent-devices"]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?[/quote]

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.
