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

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?

Ok hvala, probat ću.

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
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.
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?

Without having the drone on the table it is very hard to say something. This is one of the very rare cases.
What I notice is that the baro temperature is unusual high. Of course I don't know, how long the drone was powered on and what environmemt is around. IMU temperature (not available in this GUI) should go up to 36°C and stay there when IMU heater regulates down.
The values sent by acc and gyro are looking plausible. Nothing special that points us to a problem. But we cannot see the calibration values.
I do not exactly know, what the GUI interprets as not working IMU. Unfortunately the GUI is not very precise in this case.
The first step would be to go deeper in it to clarify above mentioned points. Two possibilities:
- If the camera is connected to the ST16 via WiFi (and notto USB) the ST16 should record Sensor files in the flight logs. Those files contains the raw data, the same as going to GUI if cennected over USB. Send us the latest files that are >100kB.
- Use the upgraded GUI (H480GUI) from my download site: Downloads and send a screenshot from the Sensor page. We can see the System status, the EKF status, IMU temperature, and some other values.

For some reason all calibration data are gone. I have no idea how this could be happen. This is the first time I see such a behavior. The calibration data are values that are stored in the R/W memory of the CPU of the flight controller STM32. As we see, all set to zero.
Not only the sensors on the MCU board are affected but alo the compass on the GPS module. It looks like a common problem of the firmware.
I would try to downgrade and update the flight controller FW and do calibration again. A description how to downgrade/update the FW is in the file behind "Reset Typhoon H flight controller" on my knowledge page:
in section How-To's.

Guys, I'm giving up, I tried everything you told me to do, I think the drone will easily fly into the trash!!!!
Thank you for everything

Zamjenski kontroler leta puno je jeftiniji od gubitka drona i nije ga teško zamijeniti.Možete čak razmisliti o premještanju kontrolera leta s drugog drona kako biste bili sigurni da će zamjena omogućiti rad drona.
A replacement flight controller is much less expensive than loosing a drone, and they are not difficult to swap out.
You could even consider moving the flight controller from your working drone to ensure a replacement will resolve the issue.
Ne.
Daj mi trenutak. Pronaći ću neke videozapise koje je dostavio @Steve Carr koji prikazuju upravljač leta i kako ukloniti gornju školjku. To je jednostavna promjena koja ne zahtijeva alate, nakon što se ukloni gornja ljuska.
No.
Give me a moment. I will find some videos provided by @Steve Carr that show the Flight Controller and how to remove the top shell. It is a simple plug-in change. once the top shell is removed.
