I can't pair my cell phone with osmo 3 via bluetooth.
I tried to reset the bluetooth by pressing the three buttons but it doesn't seem to do anything.
I don't have osmo mobile 3 in my list of devices.
What could be happening?

I think the bluetooth is off.
The led is yellow.
How do I turn it on?

Hello and good day inosen. I am sorry for the trouble and thank you for reaching out. I will be posting a DJI tutorial video on how to activate and connect your DJI Osmo Mobile 3 to your mobile device. In addition may we know what is the model of the mobile device you are using please? Thank you.

My device is Huawei P20 Pro.
The first time I could pair without problems, but when using it after the initial installation does not work.
I deleted the pairing from the phone, and I have not been able to pair them again

DJI Stephen can you help? Tomorrow I will start travel 3 weeks and I will not be able to my osmo 3.

Thank you for the additional information inosen. Have you tried uninstalling and reinstalling the DJI Mino application to see if the issue will still persist? Thank you.

Yes, persists.
The osmo 3 does not appear in the list of bluetooth devices of the mobile either.
Can it be that the osmo 3 bluetooth is off?
How can it be turned on?

The osmo 3 light is always on in yellow.
In the manual it says that this means that the bluetooth is switched off, but there is no way to switch it back on.
