Bluetooth on 3.6

badwhip

I updated and put the entire update folders on my radio now my Bluetooth doesn’t want to connect reliably. I seen in one of the file config or update was a Bluetooth settle with 0 in it what is this setting from the factory?

So after 4 or five reloads of this software it finally started working I believe the problem was my phone android 15 and or software had problems with permissions. It kept asking for them even though they were turned on. The phone would say successfully linked but then not be and on phone would connect disconnect every three seconds and ask for permission for contacts and call history. But after a few reinstalled it took.

Please give more info. Are you on dudu7/6/5/4/3, or on a 7862/8581 where you installed DuDuOS?

Sorry I have a Dudu 7 radio I was on software 3.5 never had any issues with Bluetooth til this update. I am going to try changing the 0 to 7 in the config file that had Bluetooth setting in it.

Tried reloading firmware a few times then tried to go back to 3.5 and it wouldn’t let me. I tried another phone to see if it was a phone issue but no same thing it says connected but then it doesn’t then it times out.

I unpacked the 3.6 for dudu7 and the FYT.prop simply contains sys.fyt.bluetooth_type=7. Your sys.fyt.bluetooth_type=0 is a bit strange.

Anyway: You can downgrade by first running an up-to-date lsec6318update and a totally empty file "lsec-downgrade" in the root of your USB stick. Do not add anything else. "flash" that one. Then flash again with 3.5.

Didn't work for me - I had to:

Unpack v3.5 to USB root
Copy lsec6318update from v3.6 to same USB root (v3.5 didn't work)
Add empty file "lsec-downgrade" to same USB root (else it will show timestamp error and downgrade not allowed even if beforehand you do the isolated flash)
Flash from that USB

Call it a Frankenstein USB stick but it worked ind terms of downgrade. Trouble is that after the downgrade to v3.5 Dudu Launcher won't start so I'm stuck...

The default Bluetooth value for DUDU7 is 7

Yes, you are right about the combination of the firmware and the lsec-downgrade file in one go.
Sorry. I misinterpreted from the Telegram channels.

gismo hello. Were you able to get it to finally work. You mentioned the Launcher won’t start. Thanks

Mgoodine Once, when I was downgrading to version 3.5, I used Car Launcher Pro to go into Android settings and clear Dudu Launcher Pro data. I suppose it would be possible to clear the launcher data and then downgrade, but I haven't tried that, maybe someone else knows?

gismo

Mgoodine yes - you need to combine the downgrade with a factory reset to clear data. I didn't do the downgrade at the time because i) I didn't want to reconfigure my rather complicated setup and ii) my issue got solved in the next beta so all good in v3.6 since.

Downgrading to 3.5 requires clearing the desktop data or manually updating to the latest version of the desktop.

Slavus

DUDU-Meng yes, but you can't do anything cause of launcher stop working. I used another launcher automatically started and then i cleared data.
