88w9098 TX continuous mode

[javadR3]

Hi,

I am using M2-JODY-W377 module and want to set the TX power in the tx_countinuous mode.

used these commands:

echo "rf_test_mode=1" >> /proc/mwlan/adapter0/config
echo "band=1" >> /proc/mwlan/adapter0/config
echo "channel=128" >> /proc/mwlan/adapter0/config
echo "bw=4" >> /proc/mwlan/adapter0/config
echo "tx_power=10 2 2" >> /proc/mwlan/adapter0/config
echo "tx_continuous=1 1 0xAAA 0 3 7" >> /proc/mwlan/adapter0/config

but it seems, module doesn't start to transmit(can't see anything on spectrum analyzer).

if I don't set the "tx_power", it start to transmit but it doesn't stop with 'echo "tx_continuous=0" >> /proc/mwlan/adapter0/config' command.

Another question: In UM11490 document it is mentioned that "The commands(tx_power) only set power if caldata is already loaded in the firmware", But it isn't explained HOW? What is this caldata?

Hi @shaun_wu,

Thanks for your reply. I also changed the bandwidth but still same results. when I use the following set of commands

~# modprobe moal mod_para=nxp/wifi_mod_para.conf
~# echo "rf_test_mode=1" >> /proc/mwlan/adapter0/config
~# echo "band=1" >> /proc/mwlan/adapter0/config
~# echo "channel=128" >> /proc/mwlan/adapter0/config
~# echo "bw=0" >> /proc/mwlan/adapter0/config
~# echo "tx_continuous=1 1 0xAAA 0 3 7" >> /proc/mwlan/adapter0/config

it starts to transmit but doesn't stop by 

~# echo "tx_continuous=0" >> /proc/mwlan/adapter0/config

 And by using the below set of commands, it even doesn't start to transmit.

~# echo "rf_test_mode=1" >> /proc/mwlan/adapter0/config
~# echo "band=1" >> /proc/mwlan/adapter0/config
~# echo "channel=128" >> /proc/mwlan/adapter0/config
~# echo "bw=0" >> /proc/mwlan/adapter0/config
~# echo "tx_power=10 0 2" >> /proc/mwlan/adapter0/config
~# echo "tx_continuous=1 1 0xAAA 0 3 7" >> /proc/mwlan/adapter0/config
~# echo "tx_continuous=0" >> /proc/mwlan/adapter0/config

 I also tried different parameter values for "tx_power", but nothing changed.

Here are the output messages of the driver.

Hello @javadR3 

You should set tx and rx antenna configuration.

echo "tx_antenna=1" >> /proc/mwlan/adapterX/config

echo "rx_antenna=1" >> /proc/mwlan/adapterX/config

Hi @shaun_wu,

Tried that too, but still same results. Couldn't that be because of firmware version? The driver uses firmware version  17.92.5.p11.

Hello @javadR3 

I mean which platform you use. Could you share your test environment to us? UM11490 is for i.mx platform only.

Hi @shaun_wu,

I use a Started Kit with i.MX8 as processor and runs Yocto Linux. And also use M2-JODY-W377 which is connected to the starter kit through PCI.

Firmware: pcieuart9098_combo_v1.bin

Driver Version: PCIE9098--17.92.5.p11-MM5X17283.p2-GPL-(FP92)

card_type: PCIE9098

Hello @javadR3 

Channel 128 is for 20 MHz configuration. You cannot set 80 MHz on this channel.

Hello @shaun_wu,

I'm using Linux (pci uart driver).

Thanks

Hello @javadR3 

Which host you use?

Hi everyone,

I am facing a similar problem using the test modes exposed via proc-fs (under "/proc/mwlan/adapter0/config").

I am using an iMX8 based platform with a custom Yocto based Linux.

Tuning the radio to 20MHz channels works without an issue, but using higher bandwidths doesn't work at all.

$ cat /proc/mwlan/adapter0/config 
hardware_status=0
netlink_num=31
drv_mode=7
hssetpara=7,0xff,200,400
rf_test_mode=1
tx_antenna=1
rx_antenna=1
band=1
bw=4
channel=36
radio_mode[0]=1
radio_mode[1]=9
total rx pkt count=0
rx multicast/broadcast pkt count=0
rx fcs error pkt count=0
tx_power=
tx_continuous=0
tx_frame=1 110 0xaaa 256 1 20 0 0 0 0 0 0 0 -1 -1 -1 -1 -1 -1 -1 00:00:00:00:00:00
he_tb_tx=0
trigger_frame=0

I tried all sorts of different channel / bw / mcs_rate combinations (e.g. using channel 42, which is a defined 80MHz), but never got more than 20MHz out of the 88W9098.

We are currently on  PCIE9098--17.68.1.p136.32-MXM5X17366.p16-GPL-(FP68)(R38).

Best regards
