nRF52811 direction finding compatibility

[Martin Dobler]

Hello all,

if we design a AoA receiver based on the nRF52811 and our own antenna array, will it be able to locate beacons using Bluetooth 5.0 communication?

Kind regards,

Martin

That is what it is made for and the bill of materials could be extremely cheap! Precision remains to be seen: the IQ samples are 12bit which introduces discretisation noise in addition to signal noise, also multipath reception can cause problems.
