Hi Juliusz, Thanks for your support. I'm using the following topology to understand the diversity behaviour,
R1(AP mode) -----------> R2( Station mode) Both R1,R2 having two radio's 2.4 and 5 Ghz.I'm getting following result for with diversity and without diversity. It seems only change i can see that route changes from wlan1(2.4 ghz) to wlan0 (5 ghz) when diversity data added in the babeld config. The channel information remains as 11 and 36 for station mode but ap mode it is 255. Whether it is expecting behavior ? Please help me in this to go further.
