I get a new pixhaw yesterday and try to install it on a Hex (was an APM2.6 on it before) everything goes well if I use the USB cable to connect them with my laptop. If I start to use the 3DR original radio, the part on the lap works, but no led on the Pixhaw site will work. So I can not have the connection.
My radio from 3DR ist not the newest one but works whith APM very well.
Has any a idea whats happend?
