[RESOLVED] Bluetooth frequent disconnections / reconnections

Hello,
Since one month I have an issue with the bluetooth :
Randomly but every 10 - 120 min I have bluetooth disconnection which are followed by a reconnection.
See the following logs :

Nov 17 11:43:29 tower bluetoothd[852]: src/profile.c:ext_io_disconnected() Unable to get io data for Hands-Free Voice gateway: getpeername: Transport endpoint is not connected (107)
Nov 17 11:43:29 tower bluetoothd[852]: profiles/audio/avdtp.c:handle_unanswered_req() No reply to Suspend request
Nov 17 11:43:33 tower bluetoothd[852]: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down
Nov 17 11:43:35 tower bluetoothd[852]: /org/bluez/hci0/dev_38_18_4C_3E_A0_29/fd2: fd(39) ready

I tried to downgrade the bluez package fron 5.62 to 5.60-1 since it was working fine a few montgs ago.
I have the following packages :

    ~  sudo pacman -Qs blu                                                                                                                                                                                                                                                                                                                  ✔

I do not know how to debug or investigate further, does someone would be kind enough to help me invesitgate this issue ? or point me in some good directions ?

I did not found any solution to this problem.
Maybe it is the wrong section to ask ?

Re: [RESOLVED] Bluetooth frequent disconnections / reconnections

I'm having this issue too. At first I was having random disconnections, now the headset won't connect at all

Bluetooth service is active but this is the last record:

src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down

I have tried downgrading bluez (bluez, bluez-utils, bluez-libs) to 5.61 and 5.60 with the same result. Another similar post recommended trying pulseaudio-bluetooth instead of pulseaudio-modules-bt. I found no difference in this case.

When trying to connect manually through bluetoothctl I get the following error:

Failed to connect: org.bluez.Error.Failed br-connection-page-timeout

Other devices like phones work correctly.
