Android Bluetooth 5.1 Direction Finding (AoA / AoD) in android app.

Tasawar Khaliq

Hi,
    As an IoT Mobile app manager, my company goal is to provide development services for iOT-based (Android/ iOS) apps. We are currently developing an indoor map or positioning system product. As BLE 5.1 now supports direction finding of BLE devices so that users can track their location or position according to nearby Bluetooth 5.1-based beacons or devices.

We have an nRF52833 DK board-based device and Android mobile supporting Bluetooth 5.2 So how can I check the AoA /AoD or antenna Array whatsoever data is required to calculate position, in the nRF Connect app? Any info on Advertising data to check the direction data is available in the nRF52833 DK board which we have? OR by Default, the firmware of the nRF52833 DK board is not showing the direction-finding features and we have to write the firmware? If yes then from where I can get the demo firmware to test the direction-finding feature?

Also, we have an nRF52840 DK board but I think that not supports direction finding.

Please help and explain every concern in the question because we develop apps using the nordic board.

    I know that not all smartphones are able to use this, but I've seen a few that brag about being able to send CTE's

    I was mainly thinking of Huawei Honor View 20. Last time we checked it wasn't supported by Android or iOS, and haven't seen any mention of it in later releases either.

    Does that mean that iPhones have support for CTE?

    I am not sure, but I do not think so.
