Q Light Controller+

Hi Massimo ,

You have removed the 'Close' button and access other aspects of the Raspberry Pi other than the QLC software. You will have done this to limit the demands on the resources of the RaspPi - but I think you have only ever configured the Raspberry Pi using an Ethernet cable. I was trying to connect to it using a Wifi dongle - but I can't get access to the Wifi settings - to type in the Wifi password.

Have you missed this or are you restricting QLC on RaspPi to only be accessible via an Ethernet cable ?

[ ByTheWay - Because you have removed all the close buttons - When you open the "Monitor" you can't close it again ]

thanks

Greg

Hello Greg,
what is the "close" button ??
If you are referring to the possibility to close windows, then it's a side effect of not using a window manager. Please do not point the finger. It's something that I don't like.

Also, if you searched the forum before pointing the finger again, you will find that some other users are able to configure WiFi dongles.
I did the tests myself, and as you can see the web interface allows a basic configuration of the WiFi, so it's indeed possible.

Last thing, for the millionth time, and as explicitely suggested in the user guide, the Raspberry Pi image is not meant to do project editing.
If you tried to open the monitor, then you clearly haven't understood the purpose of this software.

Hi Massimo ,

No I do understand the fanastic use of the software - it is just that I clicked on the monitor and then couldn't get rid of it ( that's all ).

I think the browser access is brillant - I was just trying to set it up and had had a nightmare to that point - but I am still missing something :-

Your QLC RaspPi manual mentions getting access outside of the QLC, to the Network Configuration and other places. You mention an "Apply Changes" button ( which is exclusively for the RaspPi and not on the Desktop version ). I am also looking for the project AutoStart. Your manual talks about a "Reboot" button - and I can't seem to find that - either on the monitor attached to the RaspPi nor the Web page attached to the RaspPi. [ It might be on the update that you sent out last week - but I didn't see any mention of it in the Release Log ]

Sorry - No pointing fingers - I was just trying to make sense of what I saw. No offence intended - in fact completely the opposite - I am in absolute awe of what you produce and your attention to detail. You are a true professional

Thanks

Greg

>I am also looking for the project AutoStart

at the start up the there is a start of
service qlcplus start

there is the startscript
/etc/init.d/qlcplus
you can see, that qlcplus starts with -o /root/.qlcplus/autostart.qxw

*
If you have problemw with setting up WLAN, tell me, so I can give you the exact information how I have done (and configfiles).
On a "normal" raspbian there is also the commandline tool, wpa_cli (I'm not shure wether it's on the qlcplus image.

I agree, it a great software on great operation system.

about the reset button it is in the web interface, in the system configuration page
about the apply changes button, it's still in the web interface, in the system configuration page, and if you need to use the rpi direct interface to create or save a project to that will be auto loaded at the boot, you need save the project that you want use in this way in the hidden folder called .qlcplus in the root folder. if you load a project from the web interface and check the radio button with "use the current project at the boot" and use the button "apply changes" (ever in the web interface) your rpi save the project that you currently use with the web interface in the right place and with the right name (and overwrite the project that you had load before, if you got one)

about the Wi-Fi configuration, I had success to configure my d-link wi-fi dongle, and configure it like access point (in this way I don't need to use a wi-fi router, only use the rpi).

there are a lot of guides to use a wi-fi dongle on rpi, but the first thing is to use a compatible dongle! and every dongle model needs a different configuration and got his personal problem...
after that, you need to configure the drivers, install via apt-get the wpa_cli and configure it (I've do it with the first rpi qlc+ image, maybe in the last one it's installed from the scratch) configure the ifconfig and if you need to configure it to work like an access point, add a software to make rpi to work like a dhcp server, and configure the system to receive directly the connections from outside...

isn't easy, is all from shell, it's sometime annoying and sometime frustrant, but you can do it if you want it really!

rpi got only few resources, it's silly to lose them with facilities for every thing, every one and every situation... (windows got it? use windows... do you want it on rpi? ask to micro$oft to develop a version of windows that work on it... and pay for it )

the rpi spirit is to learn, working with a cheap and limited device.
learn about linux
learn about our way to look at the world and at the problems
maybe learn something about us...

Thanks for your help guys ... Great ideas

The RaspPi and it#s web interface work fantastic on my home router - but when I try and do the same things on the router that I going to use at the theatre it all falls over.

I think the RaspPi as a DHCP Server is a neat solution - but is probably a little way down the line for me - I have much simpler hurdles I need to conquer.

thanks again guys

Hi Greg,

I have on my site some information on adding and configuring WiFi on the QLC RPi.

http://traylorhead.com/wp/?page_id=20

It's information I gathered and edited when adding it to my Raspberry B+ and works. One limitation I have found when using a USB WiFi dongle is the limited distance. But within the distance it works fine.

Enjoy

Hey Jimmy, that's a nice one article. Thanks for sharing.
I could think of creating a sticky post in this forum with useful information for the Raspberry Pi collected from users.

Regarding missing packages, do you believe it is worth adding the DHCP server to the image ?
As for hostapd, wasn't it already present ? I thought I added it with the wireless tools...

Just a minor comment on your tutorial: the QLC+ image default user is 'root' so all the commands shouldn't be called with 'sudo'

Hey Massimo,

That's odd as when I try calling the commands with sudo if fails. I don't know if it's the way somehow mine is configured or what.

I did get QT loaded but I guess my heart is more into my music than programming now and just could not get in gear to figure out the structure. I will continue to add comments and recommended improvements on the forum.

Massimo,

I am loading from scratch on a new card and yes you did include

apt-get install hosted

in the build

Hiya,
I have QLC+ and Jinx! (LED Matrix Software) running on a laptop. I am using a Generic RS485 interface for the DMX and a Teensy with Octo running the 1024 Matrix. I control both of these wirelessly from my iPad using TouchOSC, using OSC for the QLC and wifi midi for JinX! It all works brilliantly. QLC+ is amazing.

I have now put QLC+ on a Pi to take a midi O/P from our Drummer's drum Module to sych a subset of lights/leds to the drums. The Pi recognises both the midi interface and the DMX interface, but I would like to control the Pi wirelessly from the TouchOSC. So I think I need the Pi to be a Wifi Server but I can't install the DHCP servers etc. I don't really know what I am doing but it's looking good thusfar. Are you planning on adding the relevant packages to the image?

Hi Jimmy
I have followed your article to set up an ad-hoc wifi on the raspberry pi with QLC+
but it keeps failing I am pretty sure the coding is o.k. as i copied and paste most of it when i run the Test Hostapd configuration i get an error that seems to be the root of my problem it comes back with:-
root@raspberry-pi:~# /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'
Segmentation fault
I even changed my wifi donhgle to the one in your article in casethat was the issue
but I don't even get a blue LED come up on it
As a bit of a newnbie to all things linux and Pi i am a bit out of my depth
Hope you can help
Pete

Hi

Thanks Massimo for the new image including the DHCP server. I have a Railink Wifi Dongle. I have set the system up as per http://traylorhead.com/wp/?page_id=20. I had some problems but omitting the driver name in the hostapd.conf seemed to solve that. What I get now is a wifi connection from Windows 7 saying 'Limited Connection'. So I can see it but not connect to it. Also in the web interface configuration screen I now have a second Wifi connection called wlan0.mon for some reason?

So I have QLC+ running on the Pi, I have a generic RS485 interface which works perfectly. I have a midi interface also connected, which works. I want to be able to connect with TouchOSC via Wifi and that is eluding me at the moment. Any help on the limited connection status and the wlan0.mon would be appreciated.

Thanks

Jed
