Nope, no indication, no errors. I remember hooking up the first of the last two and getting the slow pulsing blue LED. I clicked U&E in FW-tab and it said it couldn't get device in bootloader mode (not unusual) and to do a manual update, so I disconnected USB, closed LP, restarted LP, clicked Rescue, then U&E and connected USB. All went as expected. After U&E finished, I dis- and reconnected and all seemed well. I ran the setup Wizard and up 'till setting mixes it all ran fine, then GCS got stuck. I rebooted and my settings were gone. So I hooked up the other one and got exactly the same results. That's when I started looking for a way to get the CC3D's working and I found the CF/BF method.

I wouldn't give up.  The motor(s) run(s).  It should be a simple thing to figure out at this point.
I never do. I get frustrated and to prevent great damage to things around me, I quit! For a while at least, but I always get back on it.

GCS General / Re: Settings not saved to CC3D Flight Controller

Look here for the ongoing saga.

Short version, use Betaflight or Cleanflight flash_erase command line option until we get a better understanding of what makes this happen lately.

GCS General / Settings not saved to CC3D Flight Controller
« Last post by [email protected] on May 20, 2019, 10:41:23 pm »
Hello,

I try to configure a CC3D Flight Controller, using LibrePilot 16.09.
But I'm not able to save any setting back to the controller, the save button shows simply a red cross (see screenshot).
Also the Vehicle Setup Wizard is failing to save the MixerSettings.
The Firmware looks good, I tried already to Reset, Erase and Load (Upgrade) the Firmware as stated in many other posts.
I also checked, if the controller is armed, but setting "Arm airframe using throttle off and:" is "Always disarmed".
But I have no clue what's wrong. May be someone can help me?
I upload the GCS settings as well as the UAV Settings from the CC3D.


Thank you.

kind regards Bernd

How do I know which AuxMagOrientation I have it at?
Generally, any GPS that has a mag built in will have an arrow that points forward.  With that, OpenPilot Platinum, and DJI Naza GPS/mag use 0,0,0 mag orientation setup.  Others have an I2C aux mag that must be set 0,180,0 or 180,0,180.

I saw somewhere that said the antenna side (not the PCB side) should point up.  If I do that I cannot see the LEDs.  Is this an issue?
That's right (ceramic antenna up).  The square ceramic antenna is mounted facing the sky.  There are LEDs on the FC that tell you more than GPS LEDs.  To arm (besides setup), the default is that you must have 7 or more sats, the GPS PDOP must be a good value, and the mag must be green.

Will the calibration procedure take care of both mags?
Yes, but generally an aux/external mag is more accurate than the onboard mag, so I don't let it dilute the good external readings with less accurate onboard readings.

I still don't understand the trim comment.  The throttle goes from 0% to 100%.  100% makes it go up, fast.  0% makes the motors shut off.  25% makes the quad go up but not as fast, so somewhere between 0 and 25 will hover.
All of the non-switch arming settings use zero throttle and another flight control too.  If you trim the throttle so that low stick doesn't go to zero throttle, then you won't be able to arm.  Likewise if you trim e.g. yaw, it won't see full yaw in one direction and if that is your arming direction, it won't arm.  Throttle must really be zero, but as I recall, the other channel doesn't have to be 100%.  It is less than 100%, so it would need a lot of trim or dual rates on low rate to keep from arming.

Will I have to find the sweet spot every time I want it to hover?  How can that be possible if I can't see the quad?   Can I define that 50% is hover with 100% up max and 0% off?
With Manual thrust mode you can't maintain an exact altitude without seeing it.  Even the difference between fully charged battery and lower battery changes the hover throttle stick position.  There are thrust modes that use the barometer to maintain altitude.  AltitudeHold does the obvious thing, except that zero throttle stops the motors (a safety feature).  AltitudeVario has 50% throttle doing AltitudeHold (it has hysteresis, so it's actually 40% to 60% stick).  AV has 100% throttle stick doing a slow (baro controlled) climb, and 1% throttle doing a slow descent.  0% stops the motors.

Take off in Manual thrust mode and switch to AV in the air.  I wouldn't bother with AH.

25% throttle hover? !!!  That is either a very powerful quad, or it is mis-propped, mis-calibrated, or mis-configured?

Over the weekend I hooked up the mag using the Flexiport and I2C.  It works but I haven't had a chance to Calibrate and test.  The wind hear was blowing at 20 mph so I didn't think that would work.  :o 

How do I know which AuxMagOrientation I have it at?  It is on my GPS that is now on a pole.  Also, I saw somewhere that said the antenna side (not the PCB side) should point up.  If I do that I cannot see the LEDs.  Is this an issue?  Will the calibration procedure take care of both mags?

I still don't understand the trim comment.  The throttle goes from 0% to 100%.  100% makes it go up, fast.  0% makes the motors shut off.  25% makes the quad go up but not as fast, so somewhere between 0 and 25 will hover.  Will I have to find the sweet spot every time I want it to hover?  How can that be possible if I can't see the quad?   Can I define that 50% is hover with 100% up max and 0% off?

Can you try the following firmware with your GPS ?
Rescue > Load attached firmware > flash
Set speed to 57600 + UBX, GPS can be powered after you start the autoconfig.

Remember the UBXRate will be lowered if your use baudrate bellow 9600bauds.

As I recall, that kind does not save settings permanently.  It doesn't actually work with OP/LP CC3D, but it still should work correctly with Revo set to AutobaudAndConfigure as it gets configured each time it is powered up (notice that the eBay item shows that a Revolution is connected).  It does not have a mag/compass which is another things you usually need to fly GPS flight modes.

I suggested Ohming it out since you probably use a different cable / connector when connecting to UCenter.  It would also be an equivalent test to configure your Revo as ComBridge so you would use the Revo instead of a USB to serial converter (FTDI), and thus you would use the same cables as during flight.

Here's a link:
https://www.ebay.com/itm/OP-GPS-w-LED-for-Openpilot-CC3D-Revolution-EVO-Atom-Mini-CC3D/332166264277
I'm using rev 16.09

As for ohming it out, it's pretty clear it does transmit, as u-center shows the received data, and I did try swapping pins with no effect.
It does not seem to do anything with a received signal however. I can't change anything with u-center.
If I try to config and reset to defaults, nothing happens.
In the messages view, I can see items not greyed out under NMEA, but I can't disable any of these messages.
I also don't see any UBLK items.

Additional question:  what GCS version do you use ? 16.09 or latest Next ?

Ich möchte kein Fluggerät konfigurieren. Ich wollte ein Bagger über die cc3d mit esc steuern. Oder gibt die gibt es davon irgendwo ein Tutorial  von ? Die Fernbedienung habe ich soweit ein gelernt.
