We are using CYW920721 eval kits for our development. When we measure the tx power using Cybluetool, does not give max power according to the datasheet. How to make sure the power setting are correct and it is using right power table.

Which command are you using?

When you set the tx power, please use the power table setting and set the index to 0. Don't set the power in dbm.
