Forums - Windows library

Hi Robin,

Unfortunately, there is currently no plans for a windows version of the AllPlay SDK, unless OEMs push us to.  However, AllPlay is built on top of AllJoyn, which has a windows SDK.  More work is required on your side to discover AllPlay's AllJoyn interface and communicate.  For more information, please see AllSeen Alliance's website and download the try out AllJoyn SDK.

I just managed to remote-control my Gramofon AllPlay player using the AllJoyn "IoT Explorer" Microsoft has in the Windows Store.

After that it's actually a pretty easy shot to write your own player using the AllJoyn studio to auto-generate the code needed!

MSDN/Channel 9 has pretty good documentation on how here:

https://channel9.msdn.com/Blogs/Internet-of-Things-Blog/Using-the-AllJoy...

So if I were to create a alljoyn app, is it possible to play a synced song to multiple speaker or a zone just using alljoyn ?

Or is Allplay click required for that.

Thanks

Hi,

Once you try out windows alljoyn and understand how it works, you should be able to see the alljoyn interface to allow you to group multiple speakers and play to a speaker.  Once the group is created, playing to the player you called the command on to play a song, and it will be synchronized to other speakers.  Synchronization is done internally, as this is proprietary.

Thanks

@daniel.tai

Is the grouping inside the net.allplay.ZoneManager interface? (ie CreateZone and SetZoneLead).

If I want to make my own AllPlay player, for instance throw a service on a raspberry pi that does essentially what the Gramofon does, how would I implement this "proprietary sync" ?

Hi I ended up creating Python bingings for Alljoyn located at

https://github.com/glennpierce/alljoyn_python

There is also a basic app to control my allplay speakers there.

The zone is the problem due to lack of documentation.

The introspection data for the only two methods are

Hi glennpierce,

Since you are controlling speakers, you do not need to implement SetZoneLead, this is for player only, but you are on the right track to implement CreateZone.

You are half right on putting the device id for slaves, and what you need to do is to put in the format of net.allplay.MediaPlayer.i<deviceID>.  Sorry for the lack of doc here.

Do you need to keep in mind of CreateZone's timestamp, as you don't need to parse the output slaves if the timetamp is older than the latest.  You will get a signal onZoneChanged from lead player session, which contains the same data.  This is sent to all sessions connected to the lead player.  So if you have another instance of an app somewhere, itself can also update according to the data.

Hope this helps.

Daniel

Thanks Daniel

I can comfirm using IOT AllJoyn client I can set up a zone with create zone and it works :) Thank you

Unfortunatly my python client and C++ test does not. I have a couple of quick quieries 

1, Are the device ids always constant. Could they ever change ?

2, When I send the device strings using my client the speaker responds with

ER_BUS_REPLY_IS_ERROR_MESSAGE which is unknown error.

I have tried looking a any error functions but they all return empty . Do you know of anyway to get the errors. I guess it is speaker dependent ?

I am sending like this 

Thanks. So close now

Slight update I can get errors now. I was doing something wrong.

The error is

('org.alljoyn.Bus.Blocked', 'Remote method call blocked -- destination does not exist.  Destination = net.allplay.MediaPlayer')

Need to look in why now.

Worked this out.

Works great. Thanks

I just wanted to let people know what is possible using the Alljoyn libraries

https://github.com/glennpierce/moped is my fork of the Mopidy web frontend.

I added to the settings to allow users to chose the combination of speakers they want to play to.

Being a web interface I no longer have to mess around with mobile clients. I have Modpiy installed on my Raspberry Pi2 with Kodi so its always on and available.

By looking at my code it would be easy to create something for Windows

Hi I had one more query about the Alljoyn API.

I have the Panaonic range of Allplay speakers ? Are they the only brand on the market ?

But the Alljoyn Signals do not work. Except the OnZoneChanged signal.

I have been try to get notifications for PlayStateChanged etc but I get nothing.

I have also tried to get it to workk with the windows program IOT Alljoyn subscribing to all the singals but

again I only see a response for OnZoneChanged.

Am I mis understanding when the other signals are sent.

I subscribe to the signals and then play stop songs to test.

May Panasonic don't implemt these ?

Thanks.

Hi,

There are about 20 different brands of AllPlay speakers in different parts of the world.  Panasonic only release their speakers in Europe and Japan.  I believe Bayan Audio and House of Marley may release their SKUs soon.  

As for the signal, instropection the interface of net.allplay.MediaPlayer, and you should get the list of signal to listen to.  OnZoneChanged is from net.allplay.ZoneManager, and that is different of MediaPlayer.  Please make sure you get the correct InterfaceDescription from the bus. during registeration.

Thanks

Daniel 

Thanks

I think I figured out the problem.

I will look out for the new speakers. I was judging it by searching amazon (UK) for allplay and only seeing Panasonic.

I have some .NET code for Windows 10 Universal that works with the Gramofon - I assume it should work with the other AllPlay devices too.

I've shared it here: https://github.com/dotMorten/AllPlayNet/

Still a work in progress, but most functionality is there (or easy to add the few missing calls - let me know if you want me to add something specific first).

Sorry... ended up putting it in a larger alljoyn library here: https://github.com/dotMorten/AllJoynClientLib
