Can't takeoff

[NJguy67]

I have a Phantom 2 which I have flown many times. I haven't flown it in about a year and a half. Went to fly it after charging all the batteries. Everything powered up normally, I calibrated the compass by rotating the Phantom around its axis, that whole deal as usual. But I cant seem to get it to calibrate (cant get the steady green flashing lights). Also the RC doesn't seem to be connecting to the Phantom. What to do?

Make sure all apps/firmware match.

Calibrate it in another location.

How do I Make sure all apps/firmware match?

Check through app. If you see "update required",,, then... update.

This might be dumb question but do you mean the DJI Vision App?

I downloaded the Phantom & RC assistant software. Connected both, did some upgrades and calibrated. All seemed fine while at the computer. Went outside turned everything on DJI Vision App says connected and ready to fly. Green flashing lights on Phantom, nothing happens when I move the sticks. Cant figure it out.
