Based on what's provided, it seems like the unit is trying to warm up. Just to clarify, have you ensured all the components are connected properly? Could you provide a list of your set up? Any visuals of the issue would be appreciated,

I too am having N3 problems, i have emailed support with zero response.  i have blinking red on gps and imu, blinking blue on psu,

in the assistant i get the error that the barometer is not connected.
Please Note:   this is a new installation,  still in the calibration stage of the installation. (had to purchace a sbus reciever, which is not compatible, had to order a D-Bus adaptor) which now is working. but im stuck due to cannot calibrate IMU or Compass.

I have resolved my issue after hooking up to assistant and updating firmware.

Just to clarify, is everything up to date firmware-wise? If you have more information that you supplied to Support, do you happen to have the ticket or case number that I can look up for further review?

Hi Jamie,

My Case number - CAS-454812-Z0M9X9
device was shipped today,
i am really disappointed that an brand new boxed device is faulty, costing me a fortune in shipping and loss of income. the worst is the slow responses from support, takes forever to get email replies.

Are you sending in just the flight controller, or the whole craft? I understand the frustration, the Support team will get you up and running in no time.

Just unboxed my new N3 today and connected the LED, PMU and GPS. Then connected it to the Assistant software and decided to update the firmware. After that everything failed. Getting only a solid red light from the LED indicating a critical error. N3 Autopilot flashes redPMU is flashing green and GPS compass is flashing red. Will not connect to assitant software, just a spinning icon and am locked out of the menu options. WHAT HAPPENED? How do I fix this issue. Again the N3 is brand new and under warrenty, should I send it back to DJI?

Update: I just found if I unplug and replug in the USB then I can downgrade my firmware but this has zero effect in fixing the critical error.
HELP please.
Thanks

Is your N3 powered with 24V or lower ? By default the battery alarm is set at 22V (I think
). So if your voltage is lower than 22V you get the red led.

Having a weird N3 flight controller issue myself, not sure if it stemming from the LB2 or the N3 flight controller. Throttle down is not responding to throttle stick position. Both LB2 and N3 are running current firmware.

Symtoms:
1.  The throttle stick position on the LB2 controller is non responsive to lower stick position. I can throttle up but throttling down is non-responsive until stick hits bottom then stops motors all together. stick settings in Assistant 2.1.1.2 sliders checks out fine.

2.  In Assistant 2.1.1.2 software, I’ve set all gains to their lowest values, with propulsion system bandwidth set to 150 (small props). The intention is to walk up the values 10% at a time until I get my desired results, however, there seems to be no change in behavior as a result of changes. No change in the throttle down problem.

3. shouldn't the PMU also be displayed in the Assistant software Topography screen? I only see the LED, N3 and GPS module.

Any ideas? Thanks in advance!

Is it possible to get some recommended gain settings for the N3 mounted to some common DJI airframes?  I would be particularly interested in the settings for the S900 / LB2 with the X5 camera.  That guidance has  been provided in the user manual of other flight controllers produced by DJI.  I am sure others would be interested the same settings for the S1000 and perhaps the F550.  Any guidance on this would be greatly appreciated.

Just to close the loop on this.  I was a moron.  Reading  thru the S900 manual and found this commet on page 22 of the user manual.   "DJI ESCs are specifically designed for multi-rotors.  When used with DJI autopilot systems parameters and travel ranges do not have to be calibrated."
