My prototype works well with Pi0w and GPIO Connection and this was reason I decided to reinstall software on PI3 and check once again if the same connection can work on my Pi3 or not. Until now I was using TTL2Ethernet converter for telemetry connection because I wasn’t able to connect Pixhawk directly to PI3. But if this works Pi0w it should be also possible for Pi3.

I connected a new Pixhawk to PI3 via GPIO cable and I got success on test connection. Then again I swapped to old Pixhawk ( Radiolink ) and …. its works.

Maybe my old test was done too quickly, maybe old Jessie have had a bug I don’t know but right now both configuration works well. Both RPI`s are connected do Pixhawks via GPIO and in the case of Qground Control connections works really well.

I said good bye to my TTL2Ethernet converter and I do not plan to use it anymore and I will remove it from frame tomorrow or today later.
