Dual network adapters support+"turn off" question

washburn_it

Hi,

I'm working around a Car Media Center equipped with a 7 inch touchscreen LCD.
I'm going to use 2 Raspberries, one for RuneAudio+HiFiBerry DAC+ and one with Raspbian for the "RuneUI".
Raspberries will be connected to each other through a network crosscable.
As a "plus", I would like to connect also an USB WiFi dongle that will be used to connect to my smartphone (configured as WiFi router) to be able to listen to web radios.
So, does RuneAudio support 2 network adapters?
I tried but I had some troubles with both adapters active concurrently.

The second question is: is it possible to turn off the RuneAudio Raspberry by sending a command through the network (not from the RuneUI)?
What I would like to do is to command the "power off" by pushing a button on the "Raspbian Raspberry", so with a single button I would like to turn off both Raspberries.
Thank you, regards.

Hi washburn_it,

I've done exactly the same, see here.

Yes it does, but not configureable via UI.
More on this later when i'm home.

Yes it is. More later.

But why not use a Raspberry Pi2 with the new 7" touch PiTFT.
It works great and the RP2 has enought power to handl this.
I'm working on an image with support for local webbrowser.
Should be ready in a week or two.

Hi Frank,

thanks for your reply, interesting project yours.
I bought that HDMI LCD to avoid getting "mad" at recompiling kernel and so on...it has got an HDMI input that works with every HDMI output (even with my Windows 7 laptop).
Actually I'm using a PI2 (the one with Rapsbian) since it's powerful enough to let a browser run in a decent way, and faster to boot than a B+.
The B+ is used as "server" with RuneAudio.

Yes it does, but not configureable via UI.
More on this later when i'm home.

When I tried to configure the WiFi adapter, I've made the configuration via UI and it connected to the network....the issues that I experienced with both adapters active were:

- took longer time to open the UI from the PI2 (Raspbian+browser fullscreen) if compared with only 1 network adapter active (only eth0)
- when I disconnected the WiFi, the UI didn't connected anymore from the PI2, maybe the RunAudio webserver was listening connection on wlan0?
- I had to reinstall the RuneAudio image because it didn't work anymore.

Probably it's just a matter of configuration of the network adapters (I'm not so experienced with Linux), I would like to use the WiFi just as a gateway for webradios (the router is my smartphone).
Well...I'm waiting for further info from you on this subject.
Thank you, regards.
