Wifi RF testing control - nRF7001

[Kaiyu LI]

Hello

I'm preparing the certification RF testing software on our product 4MOD9192 using nRF7001 for wifi function.

During the certification test process, we need to set these following configurations on our device:

1>>Set Channel: 1/2/6/7/11/13

2>>Set wifi mode: b/g/n

3>>Set data rate:

4>>Set band width: 20MHz or 40MHz

5>>Set RF power

6>>Set carrier signal wave

7>>Set Data Transmission (Tx) or Reception (Rx) – modulated signal test

So far, based on my research through Nordic web site, I'm using wifi_radio_test commands to control the nRF7001 to achieve these different functions mentionned above

However, for I m still not clear for some points, please help to confirm if the commands in below I used are correct or not; and please see my questions in red color in below : 

1>>Set Channel: 1/2/6/7/11/13

wifi_radio_test init (value in channel number)

 

2>>Set wifi mode: b/g/n

(I dont find a simple command to set wifi mode, based on sample code on web, the combination commands are used to set different wifi mode, but I dont know why doing so, especially for the pkt len and pkt gap commands, could you please explain?)

Set b mode:

wifi_radio_test tx_pkt_tput_mode 0

wifi_radio_test tx_pkt_preamble 1

wifi_radio_test tx_pkt_rate 1  (This sets 1 Mbps rate, you can adjust as needed)

wifi_radio_test tx_pkt_len 1024

wifi_radio_test tx_pkt_gap 8600

wifi_radio_test tx_pkt_num 10000

 

Set g mode:

wifi_radio_test tx_pkt_tput_mode 0

wifi_radio_test tx_pkt_rate 54  (This sets 54 Mbps rate, you can adjust as needed)

wifi_radio_test tx_pkt_len 4000

wifi_radio_test tx_pkt_gap 4200

wifi_radio_test tx_pkt_num 10000

 

Set n mode:

wifi_radio_test tx_pkt_tput_mode 1

wifi_radio_test tx_pkt_mcs 0

wifi_radio_test tx_pkt_len 4000

wifi_radio_test tx_pkt_gap 1000

wifi_radio_test tx_pkt_num 10000

 

3>>Set data rate:

wifi_radio_test tx_pkt_rate (value:1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54)

 

4>>Set band width: 20MHz or 40MHz

(I dont find any command to set this feature, does nRF7001 support 40MHz bandwidth ?)

 

5>>Set RF power

wifi_radio_test tx_power (value in dBm: 0 - 24)

 

6>>Set carrier signal wave

wifi_radio_test tx_tone (value:1 ON, 0 OFF)

 

7>>Set Data Transmission (Tx) or Reception (Rx) – modulated signal test

-Transmission:

wifi_radio_test tx (vaue: 1 enable, 0 disable)

-Reception:  

wifi_radio_test rx (vaue: 1 enable, 0 disable)

 

thanks in advance

best regards

Hi, 

2>>Set wifi mode: b/g/n

(I dont find a simple command to set wifi mode, based on sample code on web, the combination commands are used to set different wifi mode, but I dont know why doing so, especially for the pkt len and pkt gap commands, could you please explain?)

You can refer to 

• Running a continuous DSSS/CCK TX traffic sequence in 11b mode
  Set the parameters to run a continuous DSSS/CCK TX traffic sequence in 802.11b mode.
• Running a continuous OFDM TX traffic sequence in 11g mode
  Set the parameters to run a continuous OFDM TX traffic sequence in 11g mode.
• Running a continuous OFDM TX traffic sequence in HT 11n mode
  Set the parameters to run a continuous OFDM TX traffic sequence in HT 11n mode.

The tx_pkt_len and tx_pkt_gap commands are used to control the payload length and inter-frame gap, respectively. These parameters affect the frame duration and duty cycle, which are important for testing and regulatory compliance.
The packet length (tx_pkt_len) determines how much data is sent in each frame. A longer packet length can increase throughput but may also increase the chance of errors in noisy environments.
The inter-frame gap (tx_pkt_gap) is the time between transmitted frames. It's important for allowing other devices to access the channel and for complying with regulatory requirements on channel occupancy.

4>>Set band width: 20MHz or 40MHz

(I dont find any command to set this feature, does nRF7001 support 40MHz bandwidth ?)

No, See Wi-Fi 6 specifications supported by Nordic’s nRF70 series

thank you Amanda,  the rest of commands are OK to use on my purpose?

Another point I want to ask is that in case the WIFI adaptive mode should be test, what shoud I do? is this mode implemented in stack and no need special command to run this mode?

best regards

Please check 

• Radio test subcommands
• Using the Wi-Fi Radio sample for transmit tests
