nRF52840 Receiver Sensitivity and ADDR0

[Mike]

We are using Enhanced Shockbust and would like to maximize the operating range. We noticed this footnote on page 356 of the latest spec sheet (v1.1):

Typical sensitivity applies when ADDR0 is used for receiver address correlation. When ADDR[1..7] are

used for receiver address correlation, the typical sensitivity for this mode is degraded by 3 dB.

This note is under the Receiver Operation spec. Could you explain what this exactly means and how we should write our code to avoid this 3dB loss?

Thanks-

Well, like it's mentioned in the note; The sensitivity applies when ADDR0 is used for receiver address correlation.

Are you using ADDR[1..7]?

Don't know if it's any way to avoid this, but I can talk to some colleagues with more experience with ESB and see if they have any suggestions.

Hi Joakim,

Any updates on this issue?
I also have the same question regarding the BLE stack.

When developing BLE applications is there a way I can avoid the 3dBm loss?
