I’m on the latest firmware’s for the Mavic 2 Pro and Smart Controller and yesterday I had multiple disconnects on one flight that was in open country.  I started the drone up in my hotel room later that day and the controller was intermittently disconnecting from 3 feet away.  Not sure if I should try to retry the firmware update on both devices or if anyone else is experiencing disconnects?

Thanks!

I am experiencing the same issue on the latest update. The controller blips with the "Signal Lost" or "Aircraft Disconnected" message. It regains connection pretty quickly but it's still pretty disruptive. This is definitely new since the latest firmware update. Before the update, the connection was strong, now it's super flaky. What's odd is that it even does this with both the RC and Video stream showing full bars.

I captured a video of this behavior with the drone sitting on my dresser 2 ft away from the controller. You can see these disconnects at 0:25 (it only goes red for a frame but you see it toggling in and out of tripod mode), 1:17 and 2:44: https://www.dropbox.com/s/hmwegzfbrkipkaj/0130-213039.mp4?dl=0

It does this not matter where the drone is in relation to the controller or how strong the signal strength seems to be.

Gonna try rolling the drone back to the previous version of the firmware to see if the problem goes away. I loved this controller for 2 days and now this?

Update!

Not being one to give up quickly I decided to try a few things.
I wanted to test this out using the original controller and my Pixel 3XL which has the latest version of DJI GO4 (w/waypoints). Unfortunately, I couldn't link the drone to the old controller due to a firmware mismatch. I haven't updated the OG controller yet because the battery was at 30% and it won't let you do the update unless you have 50% of battery or more.

Anyways, by hitting the sync button to try to connect to the OG controller, it unlinked my Smart Controller. I was forced to relink my Smart Controller, and wouldn't you know it, the random disconnects have gone away. I've rebooted everything several times and so far it hasn't disconnected once. Of course, I'm not flying ATM, but it looks like this resolved the issue I was able to repeat reliably prior to the relinking. @BBradac9, is this something you can try as well to see if this fixes it for you?

As wreyniers did above, re-link the SC to your aircraft, I have had customers in the past with MPP suffering random RC disconnects and a re-link resolved the issue.

I relinked my Mavic this morning and with just a quick test inside my connection was solid, where yesterday it would drop out momentarily at times.  So seems to have fixed it.  Thanks for the tips wreyneirs!

Yep, I just flew 3 batteries after relink, not a single disconnect event. Thanks for confirming it worked for you as well BBradac9.
This should probably be in the release notes.

Oh snap. The way that HUD looks is so crisp it made me think it was CGI.  Safe flying to you then!

What firmware release number was it that was giving you guys issues? I had a disconnection that lead to me losing my drone. For some reason the RTH also malfunctioned and it is gone and it was only 2 weeks old

I had this start happening yesterday and I had just updated the remote..  In addition my Mavic continued down towards the water after I let up on the stick and then did the same while moving to the right towards a tree..  I was getting a disconnect error at that point. I thought it was all interference. I was not  in a new location and near a bridge, but then this morning at my home the remote disconnected right after I auto launched and was hovering.  I have recalibrated everything and relinked.. Going to find out this afternoon...over train tracks lol. not water if all is well. A bit safer ..

Sorry meant to say that I was not getting a disconnect while my Mavic seemed to continue flying on its own...

Not sure right now.... it just updated maybe either yesterday or  Sunday.

Sorry about your drone.

There is a find my drone function in the app.  You might try that.  I'm not very good at knowing where to look for log/txt files.

But there are folks who can help over on:
