BETAFLIGHT WON'T ARM | CALIB NOGYRO arming status flags

---

When Betaflight won't arm, you can't fly. And that stinks. I'll show you how to troubleshoot Betaflight's Arming Prevention Status Flags so you can get back into the air.

This entire series is available as a playlist so you can find the specific reason your betaflight won't arm. Get the playlist here:

Betaflight arming status flags:

One additional tip for NOGYRO that I overlooked. If your FC has a gyro with ribbon cable connecting it, then the ribbon cable may be damaged or disconnected. In this case, you might be able to replace the cable or the gyro, instead of scrap the entire FC.

"You're watching this video because your quadcopter is giving you..." Incorrect! I'm watching this because I watch all of your videos :P

4 years ago !! you haven't changed a bit ! I re -learned something today . THANKS AND KEEP UP THE GOOD WORK ;-)

Amazing. I just built a Phantom with a naked vista and i couldnt figure out why it wouldnt arm. Well, I go to the other Bardwell video to add Betaflight warnings to DJI goggles and find "calib" warning. Come to this video, and in just a couple minutes i find out that it wont freakin arm because ITS SITTING ON TOP OF MY FAN BECAUSE I DONT WANT TO OVERHEAT MY NAKED VISTA, AND MY FAN IS VIBRATING THE GYRO. Thanks Joshua.

I actually had an issue with arming after a short flight the other day and was super happy to see this series. I connected to betaflight and realized all the setting had been erased. It was like it was a brand new fc. I have no idea why it cleared all my settings but at least I don't need a new fc as of right now.

This channel is just a wealth of knowledge. Thanks Josh!

Oh man Josh i have to thank you so much making these Betaflight error videos. You helped me out in this case :D Thx a lot

[erikmattiaslarsson]

Increase of gyro_calib_noise_limit fixed my problem! Thanks Joshua!

[DanPrice]

OMG! I just noticed you finally fixed that velcro on the mic boom. My OCD thanks you :)

[stevo]

Thank you from Sept 2020. Fixed it right up!

The calib error can also occur if you have high electrical or EMF noise, for example because of a noisy 5V supply, or if you gyro is super close to your 4in1 ESC.

[dr.ozitron]

the vibration of fan of the VTX also causes this problem :)

i did fix a brand new board that someone gave me that had a[ no gyro] flag by sticking it in a small toaster oven on top of a piece of tinfoil and turning oven to 450 deg .i placed a1 inch thin piece of solder wire beside it on foil and when it melted, which once hot melted quik, i turned off oven let cool

This video is dangerous... I'm fairly new to FPV, and had a drone that was giving the calib flag... I followed this video and it armed. Myself and everyone I was flying with went "cool, see if it flies!"

As soon as I touched the throttle it ran away... it shot straight up spinning so quickly I couldn't tell what was going on and all I could do is alert everyone it was going to come down and disarm. It ended up landing on one of the other pilots (thankfully it was a crux35 so it was light and disarmed and there was no injury). It could have been way worse. It could have been a five or seven inch, and could have landed on the kid flying with us...

After feeling really dumb and doing a lot of research / debugging, it turned out the x and y axis for the gyro were working, but the z axis was dead. Increasing the threshold from 48 to 60 let the drone arm despite this.

I learned a lot of lessons, the biggest one being never test a drone anywhere near anyone else, however this video doesn't talk about any of the other things you should look at, and gives the very dangerous message that if this "fix" makes your drone arm, it's good to go. I try very hard to be safe, and I made the erroneous assumption that this video contained all the information I needed. At the very least there should be a disclaimer added to this video, if not a remake of it diving into some of the safety issues of changing this setting.

It is our responsibility as pilots to do our due diligence, and my ignorance is not an excuse. I messed up. But it is also your responsibility as a creator to not put out dangerous information without any sort of warning.

I had a Calib flag, that I couldn't get rid of, on my betaflight F7 board. After saving FC settings, I (re)flashed my latest firmware. I checked status and the Calib flag was gone. Reloaded settings, disconnected betaflight, and it armed..👍🏼

[cahePL]

I had this problem on HGLRC FC. Known issue - solder under gyro were wonky. Reflow with a good flux and all is good now :)

Joshua – First, thank you for putting this together. I almost didn’t get started in this hobby because it can become so technical. I bought a quad and enjoyed flying. Just that simple. Then when I started to build and buy advanced quads the headache started. Without your work, Blue Falcon and others I would have given up and almost did. I still have a brand new quad I haven’t figured out yet, but I will. All this stuff is just too much. It is like using your credit card, I don’t want to answer 5 stupid questions, I just want to buy it. We need an "I just want to fly the darn thing" setting in quad software. There needs to be a base config standard.

[airdevil]

Hey Joshua. Thank u.i get the calibration flag I will try this!

[JEBariffic]

Saved by Bardwell. Should be a thing. Thanks, Joshua!

I came across another fix for NOGYRO (and probably other flags). Although its probably not a very common thing to happen, if in tuning your drone though Betaflight you endup copying CLI dumps into your FC, make sure they are correct for your, well, everything.
At least for the BetaFPV drones, the company has all the default CLI dumps for each model. If you are experiencing issues like NOGYRO, try installing the default CLI dump for your model and take a look at the CLI Status again.
