Hello, Actually i’m going under the exactly same problem. I’m using raspberry Pi2 + Navio2, uname -a Linux navio 4.4.6-4d0ae01-emlid-v7+ #3 SMP PREEMPT Wed Apr 6 13:25:26 MSK 2016 armv7l GNU/Linux and i have same output above with ‘sudo i2cdetect -y 1’ i checked ‘ps -ef’ and ArduCopter-quad was not working, and i thought navio shield does not get enough power. So, i tried power with RC Battery to navio shield and it does change nothing. It was working well before, and i don’t know why no…
