Receiver address correlation in BLE applications

[Ivan B.]

Hi,

Can anyone explain what the "receiver address correlation" from 2.4GHz Radio documentation means in practice?

For example, what can I do as a BLE application developer not to have a sensitivity loss?
Does the BLE stack handle the radio peripheral on it's own to avoid this?
If not, in which cases would the sensitivity loss appear?

Thanks in advance!

Yes, as long as you are using a radio library (BLE or other protocol) released by Nordic this is not something you need to consider. It is however something you should consider if you are making a bare-metal radio driver/stack.

In short it is a hardware feature that can detect/recognize address at very low signal level (= effectively improve sensitivity by 3dB).
