Indeed.

And the support for that is not yet available.

Bluetooth 5.1 introduced AoA (angle of arrival) and AoD (angle of departure) functionality which should improve the possibilities for asset tracking. Nordic has a blog about it here https://blog.nordicsemi.com/getconnected/bluetooth-5.1-puts-bluetooth-in-its-place

Though it seems it would require nRF52811

Hi awneil,

We understood what you mentioned.

We have tested and observed as per what you said about people moving about will affect, large varitaions in RSSI when the receiver and the broadcaster are static, also when the receiver is at a height from the broadcaster.

But what do you suggest or recommend ,other than RSSI for indoor application on nrf52832 using BLE technology.

Thanks

Why do you say that?

There's a huge number of things that affect RSSI - especially indoors where you have loads of reflections, multipath, interference, etc.

People moving about will affect it.

IME, it is perfectly normal to see quite large variations in RSSI even when the receiver & broadcaster are static.

This is exactly why precise location using RSSI alone is impossible - it keeps coming up all the time on the forum!
