[Ziyao Zhou]

Hi,

I have check the document but only found sensitivity at 1M and coded phy, how about 2M phy for 52833?

Hi,

The typical sensitivity for the 2M PHY is -92 dBm. You can find more specifications in the RADIO chapter. 

Best regards,

thank you. If I am using the 251 length packet (the higest), the sensitivity will be highrer than -89 dbm?

[Vidar Berg]

No, you can see from the same table that the sensitivity increases (higher negative number) when the packet is shorter.

[Ziyao Zhou]

Thank you for your reply! So in other words, the sensitivity will have smaller or equal negative number than -89 when I use 251 length packet in 2M phy ?

[Vidar Berg]

Yes, it should be around -89 dBm when using the full packet length. Note that these are the typical numbers.
