Hi Cypress member,

I was asked about how do we modified CCA/ED configuration by our customer.

In Nvram file for Murata Type1MW(CYW43455), the following two items are written.

ed_thresh2g=-65

ed_thresh5g=-65

Can we modified them and what can we see as a result?

Best regards,

Shohei.

For dual band radios, you can consider using the following values for energy detect to pass adaptivity if using production firmware:

ed_thresh2g=-70

ed_thresh5g=-73

Alternately, if you are using mfgtest firmware, you can manually set the threshold level using wl phy_ed_thresh X where X is between 0 to -75.
