SWRU602 September 2023 CC3300 , CC3301
The set_tx command can control the entire TX datapath and front-end on the CC33xx device. This command is able to set preamble types, phy datarates, output power, control the number of data packets to transmit and the data value within the packets, and many other functions.
Default TX settings can be enabled with:
calibrator wlan0 cc33xx_plt set_tx -default 0The default settings are provided in Appendix A. The full command format is provided below. It is not necessary to include every argument in the set_tx command.
