After 4 weeks of changes to Pi0w configuration I can say config on companion computer level is done. Raspberry talk correctly with autopilot and modem. No more tweaks are required. It's looks like I do not have huge issues with video streaming and telemetry. Hi link modem works correctly and finally I can use also ddns services at boot to avoid dynamically changing IP address on ground station end. UAV starts at boot both services and I do not need more to login drone before flight to update each time IP. No-ip services are really great, I can run a UAV and after 3 minutes long time drone is ready to go. Booting process is little longer than for Pi3 but overall both platforms are working the same covering same functionality. I will say good bye to my Pi3 for a long time I think and it will be used for test purposes only soon.

I need also said that Bernt did great job with last software changes. We tested it for a few week but now this PI0w works perfect including open VPN services which I will start to test with next phase probably.

There are many changes in this phase for my, maybe I'm migrating only from one pi to another one but I think it will be a great progress. After this weekend PI3 will be replaced by Pi0w board, there will be TTL2ethernet converter removed from drone frame and autopilot will be flashed by completely new firmware - PX4pro.

This last change scares me little but as for now it only way how I can receive fully controlled drone base on LTE and telemetry only.

From the other hand all changes will make a construction reduced to minimum :). Next few days it should be mounted on my old F450 frame.
