Hi,

Can you have a look at the message information (latest on the right side of the APM Mission Planner) and check Board version and firmware version. I had one occurence of wrong firmware flash...and the board was identified as 5.1... I had to use DFU to downgrade firmware and redo the flash to latest manually with mission planner.

Latest firmware (3.3.3) is in the Virtual Robotix DropBox.

the Firmware loaded is Arducopter V3.2.1 (D472095D) -- ( i did not update to the last version because on the vrbrain site (news section) says its beta.

Hello,

Some news...

I had a try with PPM Sum on my VRBrain 5.2 board, same result as you (no signal). Pin 8 is at 3.3 volt.

Hi,
I tried PPMSUM on VR Brain 5.2 and ArduCopter 3.2.1 and 3.3.3 (latest firmware from Mission Planner) and it works fine for me. I use FrSky D4R-II with my Taranis and I see all RC Inputs when I calibrate them. I see 3.3V on pin8 if I don't connect the receiver and 0V when I connect it with the Taranis turned off. When I turn on my Taranis I can see the datastream from 3.3V down.
