I'm having the same problem as you! The Uart0/2 stopped sending data to my xbee! I haven't tried the UART0 solo... If that does not work do you have other solutions?
I'm also having some sort of problem when loading a new…"
"OK, after i was able to establish a link via the hardwired UART0 port, now i just can't. I wonder WHY. it was able to fetch parameters then eventually fail due to (link isn't fast enogh), but i thought it would work using full battery…"
"I have all ways said, since the 'lost' drone in Iran, jammed or spoofed you need to deal with loss of gps. A simple dead reckoning reality check with gps should detect spoofing. I find it hard to believe…"
"In order to get rid of such GPS spoofing, with accurate Dead Reckoning, an algorithm in the code can be implemented so that, the autopilot does not use the GPS signal for that period of time during which it observes sudden appreciable…"
"In my current build I’m using external RESET switch and UART0 from the right side of APM2 board, the new APM2 case does not have window for those connections ! I will have to modify the case before using it."
"You will need gyroscope to detect rotation and accelerometer to detect acceleration; with the two sensors working together you will be able to track your vehicle movement.
APM2 has the following sensors built in it:
"Yes I did the auto trim, but from your question about expo throttle I guess you set your radio on “Helicopter” mode which might do preconfigured mix between channels. You can try monitoring your radio raw signal using APM Planner…"
"Actually i am trying to do the same hovering test, but when i try to fly the Arducopter Hexa APM1 v2.6, in Stabilize mode, it moves in the backward direction instead of lifting and landing at the same…"
