Packet engine works only with mfgtest WLAN firmware. It will not work with production firmware. You can refer to section 4.2.4.4 WL Command Example for Data Rate testing for 2.4 GHz in https://www.cypress.com/documentation/application-notes/an225347-cypress-wi-fi-clm-regulatory-manual that will provide the WL command set to test the packet engine for 2.4GHz.
