Hello,
I'm trying to connect my apm 2.5 to my computer with telemetry.
I have solid green lights in both transmitter and receiver. I have selected the correct com port and the baud is 57600. After loading successful the 3dr Radio parameters in the inicial setup and click in connect I get an error message "No Heartbeat Packets Recieved" after the timeout.
Thanks for your help

How do you power APM? If via USB - telemetry won't work.
I suggest to change NET ID to something different than default and decrease # of channels to 30 max (if you'll lost range for longer time - then modems won't synchronize until power-on sequence).
Hello Marcin,
I have my APM powered by the battery.
I already change the NET ID (I tried 30, 50, 150) and the # of channels (I tried 30, 20 and 10) and it still does not work. When I change any value of NET ID or # of channels (in both local and remote) and I click "save settings" I get a message of "Set Command Error". Finally, I click again connect and I have the same error
If you can't change params due to error - I'm afraid that telemetry link isn't OK.
Pls try 3DR Radio config tool http://ardupilot.com/downloads/?did=89
Also - if you power down one of the radios - does the second one start to blink green (and vice versa)?
