Hi,


I've got the mini Se (European model) since april this year and everything worked fine.

Pushing how far it could go, I decided tot manually select the 2.4Ghz (in rural areas) with some Yagi boosters to increase my distance.
It all went great untill yesterday...


After a manual switch I picked a 2.4 channel (channel 2)  with the lowest green bar. Then suddenly all the 2.4 channels turned red (including the one I picked), one after the other.


I decided to try the auto switch to see if my device automatically found some 2.4 channels. But now it always picks the 5.8Ghz channels (airplane mode on), making my yagi boosters redundant.


What should I do? I really hope this is a software issue...



These are the specs
DJI MINI SE
FLY APP 1.7.4 (tried to downgrade it tot 1.16. but same problem)
AIRCRAFT FIRMWARE 01.02.0000 (via Assistant downgrade but same result)
RC FIRMWARE 01.00.0600 (idem)

Update:

Tried it on another device and same result. Gps is also found rather quickly. Any ideas?

Hi

Samsung S20 android 12 with most recent DJI fly app.
And on a Lenovo tablet with on older android version.
Tranmission shows both bands. After manual selecting band 2.4, all the 2.4 bands turn red. Before last sunday, I only had 20 flights with an average distance of 1km.
Hopefully a software issue?
Can a hardware issue eliminate the 2.4 channels?
Thx for checking this

I select a 2.4 channel manually and quickly start flying (stays green). After the landing procedure, all the 2.4 channels turn red. Auto select only possible for 5.8 channels... what's happening?
