Bluetooth cutting out every few minutes after installing BCM20702A1-0a5c-21e8.hcd

jimbotski · 04-25-2018, 03:37 PM

Hi,

I am still really new to linux so please excuse me if this is a bit low brow

I have just got going with Linux, I tried Ubuntu and really liked it and am now looking at Deepin 15.5 which I am very impressed with. Yes, I heard about the 'spyware' thing but as a JS dev it seemed to be within what I am used to and am ok with.

So, on that I was trying to connect my Apple Magic Trackpad 1 and my apple bluetooth keyboard with no success. I kept getting a firmware failure, please see image below:

https://ibb.co/d5w0Yc

I kept seeing a firmware failure for - BCM20702A1 - I copied this down to the brcm folder and my keyboard and trackpad would connect just fine with all touch gestures just working. Now however, literally every 5-10 minutes at times, all paired devices disconnect and reconnect after about 30 seconds.

Please see terminal output:

Barring some simple CL interaction with servers my linux knowledge is very limited so any help on this would be awesome. As a dev having stop every 5 or 10 minutes for things to reconnect is getting a bit tiresome.

Thank you!
