Forum Post: RE: CC2530+CC2591EM and Z-Stack 2.5.0, compilation flags

Hi,

I have been performing a packet txrx test using our device (tx) and a eval board (rx).  When I use smartrf studio tx'ing through our device I get about about  5dbm higher rssi on the receiver than when I am tx'ing from our application on an otherwise identical test setup.

The only difference I can see is that paen, en and hgm are static with the smartrf test (because it has the luxury of never rx'ing) whereas the application has to switch netween tx and rx modes frequently.

Does anyone have any insight into if/why this would account for the rssi discrepancy between these tests?

iR.
