Hi Manoj, I hope you're doing well!
Could you please take a look at the following community document?
https://community.nxp.com/docs/DOC-345405
It shows how to modify an SDK example to send a command over the air to adjust PWM using QN9080, but the steps work the same way for the KW41 or Rigado R41Z, because the stack implemented in the two devices is mostly similar.
Please let me know if you need any more information.
Best regards,
Sebastian
