nvidia jetpack rtl8812au monitor no capture

[amtcvx]

Hello,

I am running wifibroadcast successfull with rt2800usb and 88XXau, on raspberry (Raspian Buster) pi0, pi3B+, pi4, PC desktop (Ubuntu 1804), and Nvidia Nano, Xavier NX (Jetpack 4.5.0).

However, for Nvidias with 88XXau the wlan0 interface do not receive messages with svpcom/rtl8812au/v5.6.4.2.
while there are received with aircrack-ng/rtl8812au/v5.7.0 (5.9.3.2).
But messages are not more recognized by wifibroadcast with version
rx.cpp => "unknown encapsulation"

How can I use wifibroadcast with rtl8812au on the NVIDIA boards ?

Thank you for your support.
XP

1. You need to disable NetworkManager and wpa_supplicant for rlt8812au card.
2. Try with channel 165 and svpcom/rtl8812au/v5.6.4.2 driver

Hello

Bravo you did the trick !

Now I have to look how these services (NetworkManager and wpa_supplicant) disturb silently the interface in reception on NVIDIA Jetpack using 88XXau, and have no impact on other configuration.

By the way, do you plan to implement 5.9.3.2 (aircrack-ng driver), that can overide 1Mbps (88XXau rtw_monitor_disable_1m=1) ?

Thank you

Issues with NetworkManager and wpa_supplicant described in https://github.com/svpcom/wifibroadcast/wiki/Setup-HOWTO (section 7)

In 5.9.3.2 rtw_monitor_disable_1m is useless - it doesn't used anywere in the code:

$ git branch
* v5.7.0
$ git grep monitor_disable_1m
include/drv_types.h:    u8 monitor_disable_1m;
os_dep/linux/os_intfs.c:int rtw_monitor_disable_1m = 0;
os_dep/linux/os_intfs.c:module_param(rtw_monitor_disable_1m, int, 0644);
os_dep/linux/os_intfs.c:MODULE_PARM_DESC(rtw_monitor_disable_1m, "Disable default 1Mbps rate for monitor injected frames");
os_dep/linux/os_intfs.c:        registry_par->monitor_disable_1m = (u8)rtw_monitor_disable_1m;
