I'm bought on Android Store the gcs-copter app. After mailing with the developer i uninstall the app and install it directly via link (version 9 with mavlink 1.0).

I'm using the new Asus TF700T with Android 4.0.03 and connect via BlueSmirfGold to 3DR air-module. On APM2 is the arducopter 2.6 installed with the same 3DR ait-module. Both 3DR and BT-module are set to 567k baud. The 3DR is like this picture configured and connected to APM2: http://code.google.com/p/arducopter/wiki/3DRadio#Configuring_using_...

Now, if I connect my 3DR-air-module for ground via FTDI-USB cable to my desktop pc, I can select the USB-Cable-Com-Port with 57k in mission planner and can see and set all data. It works fine.

Then I connect the 3DR-air-module for ground like the circuit diagram (from gcs-copter) with BlueSmirfGold and an IC to create the exactly 3,3 power supply. I've paired the FireFly.

Then I powered the 3DR and BT up. On 3DR the green led lights solid and the red led blinks. The BT module lights red. When I start the app, I selected MAVLink. The text "Protocol selected" shown, the green led by BT lights and the "Quad+ GCS Link" goes to task. If I press "Status", I don't get any data. In between times (SOMETIMES) the green and red led on 3DR blinks. I think, I've lost the connection. By click on "Readout" and then on "back" the program was closed by himself or android.

Otherwise when the green led lights solid and the red led blinks for data, the app don't show me any data...

The connection doesn't lost, when I use the 3DR at FTDI-USB cable this is not happend. If I repower the 3DR module the green led is rapidly green solid and the red is flashing.

Has anybody the same proplem or any ideas?
