    Hello,
    Today i'm sharing with you a problem i experienced on my RN2 from the start.
    I have seen many reports on bluetooth connectivity issues, and i had always problems with my bluetooth headphones and sometimes miband. Also with the last rom was also having wifi disconnect issues.
    I was flashing from the start with TWRP the lattest dev. ROM and always performing a wipe dalvik/cash after. Sometimes, not often i made OTA updates.

    This time i finaly solved problem with bluetooth and wifi, I made a factory reset before flashing lattest ROM and voilá, all problems solved, everything works great. I was kinda sad about my MTK phone but now it's working without any issue so i strongly recomend for those with the same problems to try a full wipe update

    Thanks for the post. I had the same problem. In my case with different watches, like pebble, Google wear and gshock + different car sets and headsets.
    I used the smiui 6.2.22 weekly. Now since two days all seem to work. I have to observe is for a while though.

    I used the advanced optional option under TWRP's swiping section and deleted everything. So I had no OS installed in between. After that I installed the new ROM from SD via TWRP

    Was hoping nt to have to do a full reset but if it stops the contact disconnecting and reconnecting then great. I just hope I dont have to do this with every weekly update.

    If you backup to micloud, you only have to download apps again, but i guess it takes some time. Since i made this post i didnt have any bluetooth problems but i didnt update yet. My guess, and its only a guess, is that somewhere in the past ROM updates there has been one that corrected bluetooth and required full wipes. If thats the case then we should be OK just wiping Dalvik/cash, but let me know what you find.

    Will try a wipe system partition only and wipe dalvik and cache and reinstall see if it cures it. If not then a full reset it will have to be

    I did an app backup using Titanium Backup so it was not too bad doing a full wipe, it's just getting the settings and ringtones back to how I had them before. Hopefully this will be the end of the bluetooth problems and we can continue with weekly updates.

    That was not enough in my case at least. I had to do the full thing.

    Managed to only get 1 dropout in half an hour rather than every 5/10 mins. If starts to get irritating will do a full clean
