I recently bought a new apm 2.8 with neo 6m gps module and i configured using mission planner 1.3.39.1 build 1.1.6056.17827 and with version APM Copter v 3.3.3 quad. Did all the calibration and the quad fly's so stable in stabilize mode normally. NOW THE PROBLEM: I cant get a blue light on my neo 6m gps module, no satellites, nothing and also my apm 2.8 shows only a blinking red light not the alternate blinking red and blue but just only red and my mission planner shows gpsstatus 0
NOTE: I am testing it in my balcony on the 4th floor
And almost forgot to mention that when i detach my gps the mission planner shows GPS:No GPS and says PreArm need 3D Fix and nothing else BUT also arms and fly normally. I don't understand what's happening so help me out please!!!

Mission Planner and APM:Copter firnware will only upload 3.2.1 to an APM board even if you select 3.3.3 as 3.2.1 is the last version of copter that will work on an APM board.
Hello!
I'm sorry, but you said "mission planner 1.3.39.1 build 1.1.6056.17827 and with version APM Copter v 3.3.3 quad"
As far I know APM doesn't support firmware version 3.3.3
Or I'm not right? Would you please explain?
Thank you.
Now i got a new problem, when i switch to autotune it shows some strange movements like it goes straight up and comes down goes right and left and lands badly like the throttle killed, altitude hold goes straight up like a rocket, it gets more and more difficult to bring it back as its tough to control when it shows this behavior also my mission planner graph does not show any lines on the graph. fly's so stable in stabilize but still a jumpy throttle like staying up for 2-3 seconds and then comes down and also i feel its kinda aggressive.When i turn on autotrim and bring it in air the autotrim stops.
please help asap i want to fly it in pos hold, loiter and other flight modes but can not without autotune.
It very well could as it could glitch which could cause major issues if you are in a flight mode that relies on GPS such as Loiter or POS-Hold or are on a mission. The last thing you want is for it to fly back to China.
If you're just going to fly in Alt-Hold or stabalize then no, not really.
But it could also affect reliability for fail safes that rely on GPS such as RTL so it is best to wait a few minutes especially when you very first power it up. Subsequent powers aren't so bad as the GPS will store the info for a short period of time before the in board battery/caps drain and then it has to cold start which then takes a while to reacquire the best sats/hdop.

It will do that. They ALL do that for a while especially in doors. Even outside they will drift because they [the neo 6m] has a accuracy of about 2.5 meters. Eventually they will settle down and not drift much but it can take upwards of 5 minutes with a clear and unobstructed view of the sky.
As long as you have at least 6 sats locked and a HDOP of under 2 you should be fine. Just let it sit a bit when it gets lock for all the sensors to settle and the gps to stabalize and you're good to go.
THANKS A TON!!!!! PROBLEM SOLVED!!!!! Changed the wiring according to that order and the red and blue lights on apm started to blink alternately and when i went on my roof under 5 seconds it locked on to 7 satellites!!!! BUT NOW A NEW PROBLEM....when i put the quad on the table and it got a 3d fix on the mission planner map the quad was just sitting there, the mission planner map showed it moving and leaving a purple line as it moved. I was connected via usb and also it is kind of aggressive or its just me because i have only made 2 drones till now so not that much experience. Help me with this new problem i don't know what to do.
one or the other. As long as they match up to what I posted above you should be fine. I'd modify the wires going to the APM's socket as they are easier to swap around.
