Got Ready-toFly without GPS lock #175

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Startup in fly mode keeping GPS from locking somehow
2. Go through initialization sequence
3.

What is the expected output? What do you see instead?
The IMU board LEDs will still be flashing after IMU calibration but when 
connected to serial monitor, I get the Ready_to_Fly message, is that correct? 
In the field, I will make sure the flashing stops.

What version of the product are you using? On what operating system?
10/4/10 1160 or so

Please provide any additional information below.

I am travelling till 10/12.

My recollection is that this was a team decision to allow ground start to 
complete without gps lock.  This was due to new users getting confused when 
trying to test the system indoors and never getting out of ground start.

If you want to be sure you have gps lock before flying you can enable air 
start.  You start the system up, then when it gets gps lock and sees that it is 
not in motion it will perform a ground start.  You know that you have gps lock 
when ground start completes and you are ready to fly.  Or you can watch the 
LED's

   I would think that it just doesn't make sense to launch without a GPS lock - unless ALL you want from the APM is a FBW mode. It is difficult to see the LEDs inside our aircraft so it might be tough to see the GPS lock. Back on Rev 239 or so, I knew that I had a GPS lock already before I would get the demo_servo wiggles. That is my preference.

You still get the servo wiggles if you are in a mode other than "hardware 
manual" (ie the mux is engaged for manual control).  If you can do 6 positions 
I recommend setting up one as software manual and starting the system up in 
that mode.

Use init_home to trigger printing ready to fly
