CYW20721B2 fine tuning carrier frequency

[GeorgeD-TB]

We are using the CYW20721B2 and looking to fine tune our carrier frequency.   I heard this is done, by Cypress for this part?

I may not be asking this correctly.

Other parts we use, we can set registers to select small capacitor value increments to set the carrier frequency.  Not sure with this part how that is done.

Thank you,

George

Hi George,

Are you looking for setting the Tx power or RF parameters manually? Apparently, such settings are done in FW for CYW20721B2 chip, we do not provide access to registers to customers. 

If you want to do any particular settings for your project, please contact your local Cypress team or Cypress FAE, they can help you further with this issue.
