### Prepare

```
sudo apt update
```

```
sudo apt install dkms git python3-all-dev net-tools virtualenv fakeroot debhelper python3-twisted
 libpcap-dev python3-pyroute2 python3-future python3-configparser python3-all libsodium-dev
```

# Download and install the Linux kernel headers for rockchip rk3588

[https://drive.google.com/drive/folders/1R7VmAeo3_LpFDQvYSEG9ymAC-DvaLt47](https://drive.google.com/drive/folders/1R7VmAeo3_LpFDQvYSEG9ymAC-DvaLt47)

sudo dpkg -i linux-headers-legacy-rockchip-rk3588_1.1.2_arm64.deb
sudo dpkg -i linux-image-legacy-rockchip-rk3588_1.1.2_arm64.deb
### Libsodium

```
git clone https://github.com/jedisct1/libsodium --branch stable
cd libsodium
./configure
make && make check
sudo make install
```
### Wifi card driver

To disable add it to the blacklist:

```
cat > /etc/modprobe.d/wfb.conf <<EOF
# blacklist stock module
blacklist 88XXau
blacklist 8812au
blacklist rtl8812au
blacklist rtl88x2bs
EOF
```
Compile the driver from source

```
git clone -b v5.2.20 https://github.com/svpcom/rtl8812au.git
cd rtl8812au/
sudo ./dkms-install.sh
```
### Installing WFB-NG

Using the "nmcli" command, we find out the name of your wifi adapter and substitute $WLAN in the place

```
git clone -b stable https://github.com/svpcom/wfb-ng.git
cd wfb-ng
sudo ./scripts/install_gs.sh $WLAN
```
Enable auto-upload

```
systemctl enable wifibroadcast@gs
```
### Channel configuration

```
vi /etc/wifibroadcast.cfg
```
### Start WFB CLI

```
wfb-cli gs
```
### Video decoding

h265

```
gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H265' ! rtph265depay ! h265parse ! mppvideodec ! xvimagesink sync=false
```
h264

```
gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! h264parse ! mppvideodec ! xvimagesink sync=false
```
###GS IS READY FOR USE###

### Start, stop, restart service

```
systemctl status wifibroadcast@gs
systemctl stop wifibroadcast@gs
systemctl start wifibroadcast@gs
```
### Qground control manual

- https://docs.qgroundcontrol.com/master/en/getting_started/download_and_install.html

### Get last logs from service
```
journalctl -u wifibroadcast@gs -f
journalctl -xu wifibroadcast@gs -n 100
```
