Step 4 - Get Tx power configurations
The command get the Tx power configurations uses mlanutl utility stored at the following
location:
/usr/share/nxp_wireless/bin_mxm_wifiex/
Syntax: mlanutl <ifname> <cmd> [...]
Where:
ifname: wireless network interface name, such as mlanX or uapX
Usage:
mlanutl mlanX get_txpwrlimit <n> [raw_data_file]
Where:
Command Parameter Description
n Hexadecimal value set for a specific tx power table
0 = Get 2.4G txpwrlimit table
0x10 = Get 5G sub0 txpwrlimit table
0x11 = Get 5G sub1 txpwrlimit table
0x12 = Get 5G sub2 txpwrlimit table
0x1f = Get all 5G txpwrlimit table
0xff = Get both 2G and 5G txpwrlimit table
raw_data_file Name of the file in which the driver will save the firmware raw data
Example(s)
mlanutl mlan0 get_txpwrlimit 0 // Get 2G txpwrlimit table
mlanutl mlan0 get_txpwrlimit 0x10 // Get 5G sub band0 txpwrlimit table
mlanutl mlan0 get_txpwrlimit 0xff txpwrlimit.bin // Get both 2G/5G
txpwrlimit table and save to txpwrlimit.bin
