If you check the 54907 datasheet http://www.cypress.com/file/407801/download , you can see only 80 MHz channels are supported. Please use the attached batch file to check the 80 MHz transmit testing. This script is written keeping in mind that you are using a mfg test fw by downloading test.mfg_test application in your CYW954907AEVAL1F kit. You can put this script in C:\Users\rroy\Documents\WICED-Studio-6.2.1\43xxx_Wi-Fi\libraries\test\wl_tool\scripts location and please modify the serial port before running the script.
