Ubuntu touch Frieza ota-10.1 dropping connection to logitech k810

[Paul Spain]

I can successfully pair the k810 to my BQ Aquaris M10 FHD tablet.
The connection state flips every few seconds between connected and disconected and the signal strength between excellent and none.
I have tried forgetting the connection and repairing, and power-cycling then repeating the process, to no avail.
Both the tablet and keyboard have a full charge.
I have successfully paired and am using a Logitech Ultrathin mouse with the tablet.
I have succesfully paired and use the k810 keyboard with several Android devices across multiple versions of Android.
I have also paired and use the keyboard with Ubuntu 14.04 LTS.

I have a m10 and a k810 and a Ultrathin mouse.

I found out that I can only connect one of the to devices. If some other (mouse) is connected the logitech keyboard K810 disconects/reconects.

Testet with a dell travell mouse and i get the same k810 disconect/reconect error.

Though I can connect both mice and have them working side by side...

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm Niels observation that the K810 works ok as long as its the only device connected to the M10. As soon as I connect the Ultrathin Mouse, I lose the keyboard. When I disconnect the mouse, The keyboard works again.

I have just updated my M10 to Ubuntu 15.04 OTA-11 and the bug remains:
* I can connect my logitech k810 keyboard and it works ok
* As soon as I connect the Ultrathin mouse, I lose the keyboard, but the mouse works fine.
* As soon as I disconnect the mouse, the keyboard works again.

I am happy to provide more diagnostics if somebody would please advise on what and how I should collect.
