I have a brand new prebuilt Hexa and I'm getting constant beeping and can only connect intermittently via USB and 433Mhz Radio.
So far, I've only connected my RC Radio (Futaba 7C and a new and Newly charged LiPo). Even though the motors are vibrating, I can get the orientation/gps data on the unit (when it connects).
Very intermittent, VIA Usb, the connect timesout 8 or of 10 attempts. VIA 433 Mhz radio, the connect seems to fail 10 out of 10 times. Even though the connect fails, the motors behavior changes. Beeping will stop of a moment, a song like climbing tone starts and then the constant beeping continues.
What I've tried:
Calibrating the RC controller.
Resetting the device.
Recopying the firmware from the mission planner.
All of which hasn't worked.
Here's a video of the issue: http://www.youtube.com/watch?v=MJBuJ9BG6wk&
