I have an issue with GPS...

I get a solid blue light on the GPS Unit, but the mission planner (connected via Xbee)

does not pick up GPS signal.

0 satcount, but solid blue light...

Im at a loss!

I have had that problem randomly also. It has been around since the 2.5. Sometimes it displays satcount and sometimes not. I think that it is recorded but just doesn’t display correctly all the time. If I restart the mission planner and play back the log it most always displays satcount. I have had the same random problem with the % throttle. Most of the time both work but not 100% of the time.

I'm having the same problem all of a sudden on two units and have 3 GPS units to test with. Can you get into client mode? I can't at all. Just ignores my 3 returns.

Hi,

   I have some problems with logging.

Some time is working, most the time not.

Usually I get following messages:

Init ArduCopter V2.6

Free RAM: 2346
FW Ver: 118
----------------------------------------


load_all took 7768us

Press ENTER 3 times for CLI

GArduCopter V2.6] logs
logs enabled:  ATTITUDE_MED GPS PM CTUN NTUN CMD

8 logs
Log 1,    start 1,   end 1
Log 2,    start 1,   end 1

I erase all and get:

Log] !!Allow 30-90 seconds for erase
erase
?3 ?Erasing logs                                      ???3?Log erase complete                                logs enabled:  ATTITUDE_MED GPS PM CTUN NTUN CMD

No logs

Log]

After flying get again first message...

Any ideas?

I was getting a very similar problem. After a flight my logs were always of a historical flight and not the current flight. I did a reset and erase through the terminal setup then reinstalled the firmware and setup. Now my logs are working again. I think the 2.6 changed the way the logs erase and the old log information was not erased properly.

I had the same problem. The newest version of the firmware (2.6.1) has solved it though!

Hi,

  I’m  setting up my APM2 with V2.6 software on a Tricopter V2.5 with DT750 motors, 9x5 2 blade props, 20 AMP Hobby King Blue series ESCs and a 3cell lipo  .  I have the yaw pretty much sorted out and it  flies well in Acro and attitude modes on the stock parameters.

However I have a trim problem in Acro mode. With the stick neutral it tries to rotate backwards and I have to use about 3/4 of the available trim for it to stay put. It seems that the controller is not seeing the the neutral position on the stick as neutral.

I have tried the following

1- I recalibrated the radio twice.

2- I recalibrated the ESCs.

3- I swapped the rear motor with a one from the front 

4- I checked the C of G and tried moving it forward and this helped a little.

5- I moved the forward arms backwards about 20 degrees each and I could get rid of the trim but it still feels like it is not seeing the neutral position properly.

6- I put my rabbit controller back on put the C of G and the arms back in the right place and it still flies fine.

 

Any advice would be appreciated

 

Bob

Sounds like you just need to auto-trim it? I'm not sure if auto-trim has any effect in acro mode though.

Easiest way to auto trim is to set it to activate with the ch7 switch, then fly in stab mode giving small bumps on the sticks in the direction it needs to be trimmed until it will hover with minimal drift (in a windless environment).

Does auto-trim stay in effect until you turn ch7 back to the low position?  Or does it time-out?

Seems like it's in auto-trim mode while the switch is high, then turns off when the switch is low again, but I may be wrong.
