Wi-Fi PER Mode#

SiWx91x RCP driver supports Wi-Fi PER mode transmit and E2E mode receive functionality. Follow the steps below to verify both functionalities. 

PER Transmit#

1. See the Compilation Steps section and compile the driver, as follows:

   # make clean; make

2. Navigate to the release folder and run the following commands to set the driver to PER mode.

   # cd release
   # insmod rsi_91x.ko dev_oper_mode=1 driver_mode_value=2 rsi_zone_enabled=0x601
   # insmod rsi_sdio.ko sdio_clock=10

3. Run the following command to check 11N PER transmit:

   # ./transmit <base_interface> <Transmit_power> <Data_rate> <Pkt_length> <Transmit_mode> <Channel_no> <11ax_enable> <Rate_flags> <Aggr_enable> <no_of_packets> <delay> <Regulatory_domain>

Description of each field:

Example

# ./transmit rpine0 127 5.5 750 0 11 0 0 0 0 0 255

The above command starts continuous transmission with the following configuration:

1. Run the following command to check 11AX PER transmit:

   # ./transmit <base_interface> <Trasmit_power> <Data_rate> <Pkt_length> <Transmit_mode> <Channel> <11ax_en> <Rate_flags> <Aggr_enable> <no_of_packets> <delay> <Regulatory_Domain> <coding_type> <nominal_pe> <he_ppdu_type> <beam_change> <BW> <UL_DL> <STBC> <Tx_BF> <GI_LTF> <DCM> <NSTS_MIDAMBLE> <spatial_reuse> <BSS_color> <HE_SIGA2_RESERVED> <RU_ALLOCATION> <N_HELTF_TOT> <SIGB_DCM> <SIGB_MCS> <USER_STA_ID> <SIGB_COMPRESSION_FIELD> <USER_IDX>

Description of each parameter is as below:

Example:

# ./transmit rpine0 127 mcs0 4000 0 6 1 0 1 0 0 255 0 2 0 0 0 0 0 0 3 0 0 0 0 0 0 0 0 0 0 0 0

1. Run the following command to stop PER transmit:

# ./transmit rpine0 0

Wi-Fi Receive#

The "receive" utility present in the "release" folder can be invoked for displaying the following information.

• Total number of CRC PASS packets

• Total number of CRC FAIL packets and

• Total number of FALSE CCAs

Receive Command Usage#

# ./receive <rpine-interface> <filename> <channel_number> <start/stop> <channel_width> [user_mask]

<rpine_interface>: This parameter specifies the Base Interface (string like rpine0).

<file_name >: Name of the file into which the statistics will be logged, in addition to being displayed on the console.

<channel_number> Channel number in which the statistics need to be logged. On-air testing in DFS,; The channels should be avoided till the module is certified for DFS. Cabled tests can be made to run in these channels.

<start/stop>: Parameter to start or stop logging the statistics. Enter 0 to start logging and 1 to stop logging. 

<channel_width>: Operating bandwidth of the channel. See the table below.

[user_mask]: This is an OPTIONAL parameter and is a bitmap through which we can select group of stats defined in below section.

<user_mask>: The receive stats are divided in 5 groups. You can select any of the groups or multiple groups of stats by using user_mask value.

Giving 0 or Not argument will result in the old format.

Below table is a grouping of stats:

crc_pass and crc_fail are the common stats to all the groups.

If you do not provide the user_mask value or 0, the default stats are displayed.

Example 1: If user_mask value = 2 , below output is expected:

Example 2: If user_mask value = 9 , below output is expected:

Example 3: If user_mask value = 4 , below output is expected:

If no user_mask value is given default stats are displayed as in below image:

Once the above command is given on command line, periodically(For each sec) the stats will be displayed on the terminal.

Receive E2E Stats#

1. See the Compilation Steps and Installing the Driver sections for Wi-Fi E2E Connection.

2. Navigate to the release folder and run receive utility for E2E receive stats.

# cd release 
# ./receive rpine0 <filename> <ch_num> <start/stop> <ch_width>

Note : Make sure to disable power save while running E2E Receive stats
