Hi,
I'm using the APM2.5 with USB connection and can't receive data (artificial horizon doesn't move and all data is zero).
The OS is Windows 7 and I have tried it on multiple computers, same problem. I have uploaded both arduplane and copter firmware which installed without a hitch. No error messages. After pressing the connection button it takes a few seconds but then the parameters upload to computer and I get "done" and no error messages. But when I move the APM, nothing happens. No aritificial horizon movement. No data in status window and no raw data of any sort.
There is a continous green light "Alive!" on the APM and the TX and RX orange light are blinking in sequence. Nothing connected except USB.
I have tried resetting 30 seconds. Restarting computer, changing COM ports, changing rates. Nothing works. Soldering seems fine. The APM only arrived last week. This is symptom from the start. The other APM's I bought work fine with same computers and MPs.
Solutions? Send it back to DIY?
Greetings,
Jon
