Greetings,

I have the DJI Osmo Action 4 (latest firmware recently) and the DJI Mic 2 (latest firmware recently).

It seems since the latest firmware updates I have been having trouble.  I will loose the audio from the Mic2 at even short distances

from the camera.  During the review of the Video File there will be occasion dead air where the Action 4 is not picking up the Audio portion then

later re-acquire.  I did a factory reset on the Osmo Action 4 but that did not help.

Now to further test, I also have the Pocket 3 with a separate DJI Mic 2.  Just to make sure it was not the Mic 2 causing the problem I tested the second
DJI Mic2 with the Action 4.  It does the same thing, occasionaly.  I say occasionally because it does not happen all the time.

One more thing to add, there have been times that the Action 4 will not recognize the Mic 2 when I turn them on.  At that point I have to re-link them.

Any suggestions?

Thanks
Ron

Hi there,

Thank You for reaching out. We are truly sorry for the inconvenience you are experiencing. If this is happening during snapshot function. This is a normal phenomenon, because after Osmo Action 4 is power off, it is equivalent to being disconnected from DJI Mic 2. At this time, if you use the snapshot function to start shooting, DJI Mic 2 will need time to automatically reconnect to Osmo Action 4, so it will not be able to record audio in the first few seconds with DJI Mic 2.

Take note, if you have power of the Osmo Action 4 and power on again(not use snapshot function), it will also take a short time to reconnect, but the time is shorter than the snapshot method.

For monitor audio recording when using a DJI Mic 2 transmitter with Osmo Action 4, you can connect Type-C headphones to the USB-C port on Osmo Action 4 for audio monitoring. In the event that a you require to use the audio adapter for connection. Note that they can only use Type-C headphones for monitoring, and those with a 3.5mm audio jack are not supported.

*Note: The 3.5 mm interface only supports microphones, not headphones.
If you are not using the function above, please send us a video recording of the problem. This will allow us to investigate further and provide you with the most accurate solution based on the specific issue you're encountering.

I hope this information has helped to clarify your inquiries. If you have any other questions, kindly let us know. Thank You!

Thank you for the reply.  Non of the situations you mention are my scenario.  I will explain better for you.

When I am video recording, the Osmo Action 4 will loose connection to the Dji Mic 2. It will simply disconnect.   I have the single DJI Mic 2 not the set with Receiver and Transmitter.  

It has nothing to do with Line of Site.  You can hear in the video recording that the Mic will cut out and loose the signal and you can see it when editing the file the flat spot where it is.

This happened to me once while holding the camera on a stick, vlogging.

The mic disconnected and later in the shot, reconnected itself again. I ended up with a video clip having audio at the start and finish, but the middle was missing!

How do I send the MP4 File to you?

That is what is happening to me.  Are you using a Cage with the Action 4?

Thank you for keeping us posted. You can send us here/DM by google drive or drop box link.

We are looking forward to your response for further assistance. Thank You

No. It happened just once. Literally disconnected while I was videoing with the camera handheld. The camera didn’t go back to internal mics. Total silence for quite a few seconds and then it came back on again. All in the same clip.

I think that it might be to do with either the mic or the camera update. Never happened before. Only found out when I’d got home from Florida and edited my footage.

If this happens again, I’m going back to a wired mic.

In case anyone wants to see what it did here is the Google Drive link to the video file.

IMHO:  LOS  we all must be in Line of sight  If I turn my back to the camera or even the camera around, I can get a signal loss. I did get a longer loss with no sound as well at times. I learned to make sure the Tx sees the camera.  that is what I gotten out of the start of the vid, you turned your back and dropped well known issue. maybe down the road DJI will do 5.8ghz

Hi,

Yes the first time in the clip I agree with the LOS.  But the other time when I just twist to the left a little I don't understand that one.  You can see the Microphone was clipped to my backpack strap.  But okay technically it went Out of Sight for a second.  There are other issues I feel with the Action 4 and DJI Mic2.  I lost connection and had to relink a few times already for no reason at all.  Then the relinking process didn't work after several attempts until I did a Factory Reset on the Action 4.  I will keep playing with this to see if I can make it fail again.   I do have a question for those that are here listening.

Does it make a difference if you are standing behind or in front of the camera to qualify for LOS?

Also if you buy one of those SmallRig ALum cages would that make a difference in connection?

Thanks for the reply and comments.
Ron

My cage doesn’t seem to make a difference. It’s very open on the front and back. (Smallrig)

Yours looks like a weak signal rather than Bluetooth turning off. Mine went off for a longer period of time before it came back on again. It didn’t keep doing it.

I wonder whether there is a poor Bluetooth connection going on there? Either fault on camera or the mic putting out too low a signal?

I stand in front and can have the issues happen  too anything like said is possible.  maybe the next time it happens I'll post a vlog about it. I did too many and too lil  know about it

If there is a weak signal problem it is probably from the Camera.  Reason I say this I have (2) DJI Mic2.  One came with my P3 Kit and the other I purchased separate when I got the ACTION 4.  I have tried both on the ACTION 4 with same results.

I going to do some more testing in my backyard where there is not obstructions.  I might compare the test using the P3 also since both it and the Action 4 will pair with the DJI Mic 2.  I have (2) Mic2's one for each camera because sometimes I use a multi cam setup for my YT Videos.

I forgot to note.  I also have the same issues where I lost connection and had to pull the battery to actually get to relink.  they happen  more then random, and I tend to just continue forward.   we love to hear more so do keep us posted.    can our Smartphones interfere when vloging  mine is in my back pocket

Smartphone is a good question.  What I have learned to do now is setup the camera to automatically record on the DJI Mic 2 also.  I think it is called 32 bit recording or might be another setting.  But it is in the camera settings.  It's just not as convenient because you have to get audio tracks from the Mic 2 onto your computer and then find the correct Audio File you need.  I have to do that now when I have these breakdowns between the Mic2 and Action 4.  Strangely enough I have not noticed any disconnects when I use my P3.  I will really need to do some serious testing now that I know other people are experiencing the same problems occasionally.

I think most people stand in front of their camera and record, unlike me I tend to put my camera on a tripod and walk around a bit.

Op3 has the newer bluetooth the Action 5 will have the newer technology.
32-bit float or even simply use vid +Aud synch, my issue with DJI is everybody has an issue and mine was the   start/stop buzz  does not work, and now works after I complained Lol

I sent you a DM.

Hi there,

We are checking with the relevant team on this matter with the provided information and will get back to you with an accurate answer once we have the result.

We appreciate your understanding and patience, thank you!

Hi there,

Please check your DM, Thank You

It would be nice if possible solutions were on here for others.

As soon as I get one I will come back and post

As we all are well aware DJI can not fix the  rf issues and will be releasing a new model with the latest Bluetooth  software.

Is the RF problems with the Mic 2 or the Action 4?

Action 4 not DJI mic 2 as the Mic 2 came out after the action 4. OP3 and mic 2 work perfectly

I am putting together a test video that will show the issues.  Stay tuned I will post it here
