it is claimed that we can't use this circuit for DoA or DoD estimation

[jarmokivinen]

We are eplanning to include a simple DoA or DoD estimation in our device for BLE bracelet doirection detection. One partner claimed that nRF 52811 can't be used for this purpose. Is it so?

Hi

The nRF52811 does support Aoa/AoD direction finding. Please check out the direction finding whitepaper on the Infocenter for details. 

Please also note that the nRF52840 does not support direction finding (AoA/AoD). Otherwise, Henry_Chou is correct

Best regards,

Simon

Yep! Simon is correct. 52840 is not support direction finding. nRF5340 is....I am always confused because 52811 & 52840 are same DK. Actually , I did 820 project befoe. Thanks for simon's advice.
