Bose QC35 II keeps disconnecting/reconnecting on firmware 3.1.8

Hello, 

 

   I've got an issue on my One plus 3 with the QC35 II 

   The headset keeps disconnecting and reconnecting again.

   The one plus 3 is on android 9.0.0 firmware

 

   I've looked trough te previous solutions, and also tried the following troubleshooting steps: 

  • reset the headset, chare 1 minute, unplug, wait 30 sec.
  • reset the headset's pairing list (long pressing the on swith to the right)
  • deleting and re-pairing the phone
  • deleting data from Bose Connect app and re-pairing
  • +resetting and setting up headset in google assistant again
  • updating the firmware to the latest available (3.1.8) trought the app
  • updating the firmware to latstes tavailable (3.1.8) trough bose updater on PC

 

    Unfortunately none of these helped.

    There is usually between 5-15 minutes between disconnecting. 

    After it disconnects it reconnects itself but it is unable to play any sound.

    This results that have to switch it on and off again.

 

    Is there anything else I can try to solve this problem?

 

 Kind Regards,

    NCFK

Hi NoCountryForK,

 

Thanks for posting. I am sorry to hear about that. We appreciate all the detail you have provided. Could I ask, would it be possible for you to try to headphones on a different mobile device for troubleshooting? It would help to see where the fault may lie.

 

 

Regards,

Hello Tony_G,

 

I tried using another mobile device and I get the same result. The headphones disconnect, noise cancelling turns off and then the headphones turn on noise cancelling again and reconnect instantly to the device I was using. 

 

This morning I tried to downgrading to a previous software. I used the bose updater and "a" "d" "v" "uparrow" "downarrow" method to get acces to a previous firmware but unfortunately the only option I had in the dropdown menu was firmware 3.1.8.

 

Anything else I can do for this annoying issue?

 

Thanks in advance
