2.8.6 Set Tx continuous mode
This section shows how to set Tx continuous mode. The test requires first to load the
driver modules to bring-up NXP-based wireless module.
Step 1 - Enable the RF test mode
root@imx8mqevk:~# echo "rf_test_mode=1" >> /proc/mwlan/adapterX/config
Verify that the output value of rf_test_mode is 1.
root@imx8mqevk:~# cat /proc/mwlan/adapterX/config
Step 2 - Start continuous mode
• Packet mode
First stop any ongoing transmission:
root@imx8mqevk:~# echo "tx_continuous=0" >> /proc/mwlan/adapterX/
config
Start Tx continuous mode:
root@imx8mqevk:~# echo "tx_continuous=1 0 0xAAA 0 3 7" >> /proc/mwlan/
adapterX/config
• Wave mode
First stop any ongoing transmission:
root@imx8mqevk:~# echo "tx_continuous=0" >> /proc/mwlan/adapterX/
config
Start Tx continuous wave:
root@imx8mqevk:~# echo "tx_continuous=1 1 0xAAA 0 3 7" >> /proc/
mwlan/adapterX/config
Where tx_continuous combines six parameter:
tx_continuous= <start/stop> <continuous wave mode> <payload pattern>
<cs mode> <active subchannel> <tx data rate>
