     -i <TX burst interval by SIFS in the unit of TU >
     20 ~ 1000

     -s <short or long preamble >
     0: SHORT PREAMBLE
     1: LONG PREAMBLE

     -p <value of TX Gain , TX power = TX Gain * 0.5 dbm >
     (inside moudle S605 path loss ~3dB, it means measurements of module out is 0.5*p-3db)
     (ex: p=20, measurements of module out is 10-3)

     -t <continuous TX packet>
     0: G mode
     1: N mode

     -l <length of the payload in the unit of bytes>
-c <channel number>
     Support 2.4G/5G channel

     -r continuous RX packet and report the number of good/error packet and RSSI
-n <time of continuous RX packet in the unit of sec, number of burst frame for continuous TX packet >
     0 means unlimited for TX

     -m <CW mode>
     0: Carrier waveform
     3: Continuous waveform (100% duty cycle)

     -h print the help

   • Example TX:
     1. Continuous TX packets in specific setting (operate on wlan0 with unlimited burst frame with SIFS=30 TU, TX gain=10 , normal GI, Channel=6, Bandwidth = 20Mhz, preamble type=mixed mode, long preamble, N date rate at MCS32)
        wifitest -I wlan0 -t 1 -n 0 -c 6 -p 10 -s 1 -B 0 -g 0 -G 0 -N 32 -i 30
     2. Continuous TX packets in specific seeting(operate on wlan0 with 11b, Channel=7, TX gain=17, 11Mbps)
        wifitest -I wlan0 -t 0 -n 0 -c 7 -p 17 -R 6
     3. Continuous TX packets in specific seeting(operate on wlan0 with 11g, Channel=1, TX gain=14, 54Mbps)
        wifitest -I wlan0 -t 0 -n 0 -c 1 -p 14 -R 12
