Mouse Microsoft Bluetooth Mobile 3600

[gugu]

I have a problem with my new mouse bluetooth Microsoft Mobile 3600.

I have been reading several questions about this device on askubuntu and ubuntuforum but none of them provided a solution for my particular case.

What happens is the following: the bluetooth mouse pairs and connects just fine but, after a while (varying randomly between a few minutes and a few hours) it just disconnects and there is no way to connect it again. The only solution is to reboot the machine or to unpair and pair again the device, not a solution.

Some observations:

1. In blueman-manager 2.0.4 it sees the device as BluetoothMouse3600 but it did not recognize it as a pointing device like it does with the JETech (see screenshot). In fact, also when the device is connected and is working, it does not look connected like the MDR Headset (see screenshot). It is weird isn't it?

• In the default Debian bluetooth manager, the device result connected, but the disconnect option is in grey, meaning that you have no options to disconnect the mouse beside switching it off or shutting down the bluetooth service. In addition, also here is recognized as "unknown" (see screenshot). Weird again right?

• I tried the solution suggested here with no luck. The first command gives an error:

  Code: Select all

  guido@guido-lap-deb:~$ sudo hciconfig hci0 sspmode 1
      [sudo] password for guido: 
      Can't set Simple Pairing mode on hci0: Input/output error (5)

  And using

  Code: Select all

  bluetoothctl

  it does work, but with the same issues exposed earlier, after a while it just disconnects.

To summarize, I am struggling to find a way to have this device properly working. I have already tried with the Logitech MX Anywhere and it did not work. So I switched to a Microsoft mouse beacause a red in some forum (I do not remember which one) that Microsoft mice have good compatibility with Linux and... nothing.

OS: Debian 9 (Stretch)
Kernel: Linux guido-lap-deb 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux

Thank you in advance for your help.

What is the package in the link?

Power Management:on

^ This could be your problem, does this fix it:

Code: Select all

# /sbin/iw dev wlp59s0 set power_save off

If so then make the change permanent by creating a file at /etc/modprobe.d/iwlwifi.conf containing this line:

Code: Select all

options iwlwifi power_save=0

We do actually have a specific thread about iwlwifi with more suggestions, search the boards to find it.

What is the package in the link?

It supplies the `iwconfig` command

EDIT: nice connection you have there

Thanks. I will give it a try and let you know.

Just a question: why power management affects the functioning of the Bluetooth?? When I work at home I don't care about it, nevertheless, if I am working with battery power I would like to keep on the power saving.

EDIT: nice connection you have there

ahahha thanks!!

why power management affects the functioning of the Bluetooth?

Not sure tbh but the bluetooth connection is mediated through the iwlwifi driver so any bugs there will affect the bluetooth connection.
