Hi Folks,
after i dig out my copter for about one year of absence the first i did was updating it to the new arducopter firmware. However, everthing works fine while connected via usb.
then i unplugged usb, put my 3dr radio into the pc and powered the copter with its lipo and... the 2 radios didn't found each other. Well i thought of some msiconfigration. I unplugged the lipo from the copter and put the usb cable back in... well the 2 radios found each other immediatly.
so in short... if the copter is powered with usb the 2 radios connected immediatly. if the copter is powered standalone with lipo and usb disconnected they keep green blinking... i have absolutly no clue how this can be.
i'm thankful for all tipps you maybe want to share with me about this problem. i have no clue what to do now.

I mean printscreen from MP or 3DR Radio config tool, with config loaded from both radios simultaneously...
There we can't see FW version, if both radios has same settings etc.
this is mainly the config of both. As i said, if connected via usb they both find each other, so i'm pretty sure it's not a settings issue, maybe you can tell me what you are looking for.
I'm looking for differences between units, difference in FW versions etc.
Can you post pictures of your config while "the copter is powered with usb the 2 radios connected" and "copter is powered standalone with lipo and usb disconnected". I can't clearly understand this states...
For propper work it's enough, if both units have stable +5V power, nothing more....
Well it's simple. if the copter is powered with lipo my ground radio is not going to connect, it keeps green blinking.
But if i disconnect the lipo from the apm and connect the APM via USB to the PC too, both connect immediatly and stop blinking.
Disconnect APM from everything except 3DR radio and power it with simple BEC, connected to INPUT servo rail. Measure Vcc on telemetry port. Check, if it works.
thanks for the suggestion but i do not connect the apm via BEC:
however to disconnect the radio i have to disassemble the whole copter, this is a lot more complicated than it should be. well will do it in the next few days. I hoped their might be something i can do in the settings without changing something on the hardware.
sure...
