Operation method: Linux Command

Turn on testmode

• Connect the board to the computer with a serial cable
• Power on the board
• Read Hit any key to stop autoboot: 3 Immediately press the enter button at the serial port to enter uboot:
• Enter the following commands in order

NHX53X2-V01-222-NPN-512M16-D4# setenv bootargs '$bootargs wifi_ftm_mode serverip#192.168.1.199#'
NHX53X2-V01-222-NPN-512M16-D4# saveenv

variable

For variable definitions, see:comand options

• -J - TLV2
• -i wifiX – wifi instance X
• -I 0 (capital i) – phy identifier
• -M 0 – Set the WLAN mode as none
• —rateBw 0 - Set the Data rate bandwidth as CCK
• -r 0 – Rate is 1 Mbps
• –nss 1 - one spatial stream
• -f 2412 – The central frequency is set to 2412 MHz (channel 1)
• -p 15– Set fix Tx power as 15 dBm
• -a 1 – Tx on chain0
• -t 3 – Tx mode is CONT_TX_99: Continuous Modulated Tx 99% Duty Cycle
• -Y 5C:B1:5F:71:00:00 - RX Station MAC Address:If this option is not used packets, will be sent in broadcast 20MHz.

Tx reference commands

Hardware Variables

• 2.4G

  • -i wifi0
  • -I 0

• 5G

  • -i wifi1
  • -I 0

• 6G

  • -i wifi1
  • -I 0

Simple commands to verify Tx/Rx

• To start/stop Tx, using following commands:

myftm -t 3 (Tx start)
myftm -t 0 (Tx stop)

• To start/stop Rx, using following commands:

myftm -x 1 (Rx start)
myftm -x 0 (Rx stop)

CCK

Special tip: Execute the myftm -t 0 command first before executing other commands.
