Hi Guys
The next instalment of questions from a newbie.
my HUD in mission planner shows failsafe and will not allow me to alter flight modes. It will arm via the safety switch and responds, apparently correctly to throttle input.
Clearly it is not happy with something but is not reporting to HUD screen an RC failsafe condition., just failsafe.
I am at a loss to diagnose this until i know what it thinks is wrong, where do i look please ?
Thanks in advance

The compass is in the same place as when i did not have this issue. 3DR GPS with compass inbuilt.
Can anyone confirm this will give a failsafe condition.
Will re do the compass dance tonight anyway but if this were the cause would i not expect an "RC failsafe" condition ?
SOLVED
It appears that RC3 will not allow me to have failsafe set to disabled. As soon as i select RTL on defined failure everything is good to go. See my other thread , i have now flown 3 short test flights and everything is stable and reliable.
I hope this works and is useful
Oops file too big. will have another go

Since you say you are a newbie; (which is ok, we have all been there)
- avoid testing beta/RC firmware, until you are sure everything works fine with current release.
Current arducopter is 3.1.5 , you are trying 3.2-rc3 ,
You could also try FS_GCS_ENABLE = 0
The proper approach would be : install current firmware, 3.1.5 - tune everything, make sure it flies perfectly and get used to how it behaves "normally".
Then review releasenotes/and or code changes before installing a beta/release-candidate, then do some careful tesing, test every affected feature in a safe way.
Hi Andre
Received and understood, however, i moved away from 3.1.5 because 3.2 has a safety arm switch bypass and i was previously having huge issues with ESC calibration. I believe that is now resolved.
I dont want to bypass failsafe which i guess is what your parameter change is advocating, i dont know i have not had a chance to connect and read it yet. What i want is to understand what causes the issue because i cannot determine that as yet.
I could of course initialise the firmware, reload and start everything again but that is a pain if there is an explanation available. The same thing might still be present anyway.
Thanks again for your time

ok, I see.
Not knowing exactly what you've done (or connected, and how),I tried to make you bypass the need for telemetry radio connection to GCS - ground control station.
I just guessed that may be the cause, yet I don't see the proper log entries to confirm that.
Did the same config arm properly with 3.1.5 ?
I tried 3.1.5 on a previous Pixhawk unit that was returned to the supplier as it stopped working.That unit and config did fly once, briefly.
The replacement has so far only been used on 3.2 and has not yet left the ground. I thought i was ready to go and yesterday noticed that i could not vary flight modes and the aformentioned failsafe is prominently displayed in the middle of the HUD.
Strange that i can run up the motors when a failsafe condition exists, if i had props on it would have taken off of course.
This is not the same as an RC failsafe.
Still confused
Log analysis gives me this output....

The compass dance thing is getting to be a pain.
Is this my issue? i remember a warning about dual compass or something but do not fully understand the implications. I will re do the dance this evening.
