Help - GUI Reports Bad IMU

[dhf1405]

I have another question.
I have another drone T H pro but according to the GUI I have an error and the red and blue lights are flashing.
What could be the problem?

sorry for my english, I'm using the google translate

Is the drone standing on a flat, horizontal surface? If yes, the pitch value is out of control. Did you have done an accelerometer calibration? Maybe it needs to do more than one time to get the system back to normal. I see that the IMU sends values. It could also be that the EKF status is wrong, means that all HW sends values but the flight controller cannot bring this stuff together. Unfortunately the GUi does not show System status or EKF status.

Bad EKF status is usually the case if calibration values have too much bias.
Please start with accelerometer calibration followed by a compass calibration. My hope is that the bias will be reduced and the flight controller will be fed with correct values.

Note:
- Please do not hi-jack others thread.
- Make screenshots with computer (Alt+Print) so that we can see all in better quality.

Thanks for the answer, I did what you wrote, now it no longer blinks red-blue, now it blinks red-yellow and after a few minutes it asks for compass calibration without starting with ST16.
Unfortunately, I can't take a picture of the screen because when the GUI is up, I can't take a picture of the screen

Do compass calibration again far from buildings or metal constructions.

Napon male baterije na GPS-u je 2,45 V
Je li to u redu?

Translation by moderator:
The voltage of the small battery on the GPS is 2.45 V
Is that okay?

 

[dhf1405]

Ok hvala, probat ću.

translation by moderator:
Ok thanks, I'll try it.

Unfortunately nothing from the calibration, I tried 15-20 times both in the NO FLY ZONE and outside the zone, it blinks red - yellow all the time

Da. To je dobar napon.

Yes. That is good voltage.

Nažalost, ne mogu slikati ekran jer kada je GUI uključen, ne mogu slikati ekran.

Mnoge tipkovnice imaju gumb "Print Screen", zatim ga zalijepite u grafički uređivač da biste stvorili sliku za objavu. "Print Screen" može biti drugačije označen.

Many keyboards have a "Print Screen" button, then paste into a graphics editor to create an image to post. "Print Screen" may be labeled differently.

..... sada treperi crveno-žuto i nakon nekoliko minuta traži kalibraciju kompasa bez pokretanja sa ST16.

Jesu li se Gui indikacije promijenile kada su se promijenile boje svjetla?
Did the Gui indications change when the light colors changed?

Stražnja LED lampica može biti žuta pri pokretanju ako je glavna baterija leta manje od pola napunjena. Koliki je napon letačke baterije?
The rear LED may be yellow on start-up if the main flight battery is less than half charge. What is the flight battery voltage?

 

[dhf1405]

Nothing has changed and the red x is still on at the IMU, the only thing that changes is when I turn on the GUI, it stops blinking red-yellow and starts blinking red-blue

@h-elsner is by far the most familiar with failed and out of calibration IMU units. I will stand aside to avoid confusing the subject.

@h-elsner je daleko najupoznatiji s neispravnim IMU jedinicama koje nisu kalibrirane. Ja ću stajati po strani da ne zbunim temu.
