The direction finding sample projects are part of the nRFConnect SDK and available in the Bluetooth samples page of the NCS documentation. For information on an antenna array you will need to contact our sales department, as we here at tech support don't have details on release schedules or roadmaps.
I already have the Antenna array and tested the example provided, but it is limited to one detected module. Is there a plan to provide the SDK example of how to detect multiple tags (direction finding)?
Yes, the plan is to release more sample projects for more use cases in the future. You will have to contact sales regarding details on when this can be expected.
