Bluetooth on Udoo Neo ?

[Ken Harris]

Is it possible to enable Bluetooth on Udoo Neo ?  FYI, it uses the TI
WL1831 module.

I tried :

hciattach -n ttymxc2 texas

... but got "Initialization timed out."

I also tried various combinations of bit rates and flow control.

Any tips are welcome.

The DT bindings need to be converted to the serbus framework and it
should then just work, the old style of things for the TI wireless
used a *terrible* userspace thing that basically didn't work unless
you were facing the Netherlands, standing on one foot during a blue
moon.

I had a patch to do this but it needed some tweaking around the GPIO
power bits but my Neo has gone AWOL again. It seems if I power it from
the barrel connector I get the filesystem corruption issue, and for
some reason it's decided it doesn't want to power up when running from
the USB port.

It short: Not currently, there's not much to do, it's back on my backburner.

For reference I managed to get bluetooth working with DT changes that
I submitted upstream and this support, with some other minor udoo-neo
improvements, will arrive with the 5.3 kernel.
