If the installation of Apsync is completed and everything work , connect to the WiFi network Apsync
Open Bitvise
Username /Password : apsync
Press log-in and enter in termimal mode , we need to know the name of ethernet device
Add static IP address on Ethernet port
sudo nmcli con add type ethernet con-name ‘eth0’ ifname enxb827eb249e28 ip4 192.168.99.55/24
LTE MODEM
The USB LTE E3372 modem is detected as a virtual network device.This makes the initial setup easy.
I previous tested the internet connection on my notebook.
I will not write how to configure the USB dongle , in my case the APN were already configured
The command nnmcli device will show ithe new device "Wired connection 2 "
Try ping to google
apsync@apsync:~ $ ping www.google.com
PING www.google.com (216.58.198.4) 56(84) bytes of data.
64 bytes from mil04s03-in-f4.1e100.net (216.58.198.4): icmp_seq=1 ttl=51 time=78.3 ms
Now RPI is connected on internet

Go to https://my.zerotier.com/
Create an account and network
Copy your private ID , will be necessary to write it when the client will join your network
Install your client in your PC /Tablet/Smartphone
Join the client and your network
Now we can install zero-tier on RP
curl -s https://install.zerotier.com | sudo bash

64 bytes from 192.168.193.138: icmp_seq=1 ttl=64 time=0.154 ms
Now Apsync have a static IP address on ZeroTier network
Reboot raspberry and try to connect with VPN address
Well at this step you can reach Apsync everywhere
GROUND STATION
In SFTP Window go on /home/apsync/start_cmavnode
Edit cmavnode.conf
Go to section and add [to_pc]

TEST VIDEO
Go to home/apsync/start_cherrypy
Edit start_udp_stream

Add function test_video
function test_video {

}
test_video
Go to your client browser to RPI IP address port 8000
Start streaming
Open QCG
The gray glitches can be solved with rtpjitterbuffer
Try Gstreamer pipeline in your PC , in my case example:
d:\gstreamer\1.0\x86_64\bin\gst-launch-1.0 -v udpsrc port=5600 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264" ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false
At this point the system is ready to connect FlighController over interner and send video
Next step i will try to explain how to use and V4L2 or Encoder H.264
Video first outdoor test
