Has anyone had experience of installing a bluetooth RS232 dongle to end frequencies from SD to a radio installed in a licensed aircraft?

It's important to note that SkyDemon does not control or command your autopilot, it simply tells it about your current route, leg, and GPS position. It's then up to the autopilot to decide what to do with that information. SkyDemon would have nothing to do with your bank angle, roll rate etc.
