Thanks for a great forum.
The USB-port on my APM is beginning to get unstable so I have bought a bluetooth HC 05 to serial module. I have now digged through the forum threads I could find regarding the connections, but are still unsure as to how the module should be hooked up to the APM.
I want to be able to program the APM from mission planner via bluetooth on my computer. Could any of you possibly send me a picture or drawing describing how the bluetooth module should be connected to the APM? The bluetooth thing has 4 connections: rxd txd vcc gnd, which I believe is two communication ports, 3.3v and ground respectively.
Thanks a lot for any input.
I know the thread is old, but I just want to "close" the topic. As replied by floyd and Dave, the bluetooth module HC 05 is not worth it. I never got it to work and bought a cheap telemetry-kit instead.
