nRF52811 location

[Cy]

I see the nRF52811 has direction capabilities, but can it locate and if so does anybody have any idea as to its resolution is say a large wherehouse environment? So, could it locate itself with +/- 1m in the volume? Thank you?

Hi

The nRF52811 supports BLE 5.1 and its direction-finding features. You can read about the Angle of Arrival and Angle of Departure (AoA & AoD) in this blog post. The most accurate solutions using Bluetooth 5.1 should be able to provide accuracy down to a centimeter-level in the right environment, so meter-level accuracy in a warehouse should not be an issue at all.

Best regards,

Simon

Hi.

Do you have an example code for this that measures distance and direction finding using nrf52811? Because in the samples projects, the code is not compatible with nrf52811. Thanks.

The nRF52811 can only be used as a tag. It can transmit a packet in the correct format that and can be located by the receiver using AoA. The nRF52811 doesn't have the memory and processing capabilities to do the angle calculations. 

One would typically use the nRF52833 or nRF5340 in the receiving end.

If you want a tag to locate itself, you are talking about AoD, which is far more complicated.
