I'm now back to my local Chord dealer who kindly provided me with a Poly to test, I connected it to my Mojo2 and carried out various tests.
I was able to play from MicroSD via M.A.L.P. app but there was no way to play the files on my device (android) both in wifi mode connected to the device hotspot and in Poly hotspot mode, by connecting my device to it. With BubbleUpnP I could see the files from the MicroSD but it didn't reproduce, which I was able to do with M.A.L.P. as already mentioned.
With UAPP, on the other hand, it did not see the MicroSD and it wasn't possible to transmit music to the Poly in any way.
Have any of you managed to get UAPP to work as a wifi controller with the Poly? I paid for this app and since it has the UPnP protocol and it should work with the Poly.
Bubble UPnP works with my Poly and my 2GO and all DLNA devices since the first day I use its.
With Bubble UPnP, You have to select Poly like renderer.
To do that, When you select a reader/
You will see : in French
Lecteur Local
Chord Poly YourPolyName
USBaudioPlayerPro
If you choose Chord Poly: Your playlist will be played with Poly.
At this place you see the renderer fonction of UAPP. You can choose it and the playlist will be playable in the APP UAPP.
In BubbleUPNP: in the Library: You can find UAPP Server. It is the server function of UAPP.
USBaudioPlayerPro and UAPP Server are the names fixed in the tools UPnP renderer of the APP UAPP.
From this point, you can understand that the functionality UPNP are working in each apps Bubble UPnP and UAPP.
But from the first day i use UAPP (before the poly exist) UAPP always use the USB output of the smartphone.
I never find the place to select a reader DLNA compatible
I never find the place to select between the USB way or one renderer way like Poly, 2go or my TV who is DLNA compatible.
I resume: In Bubble UPnP
I have to select in the library of the Poly, the album and place it in the the playlist. It is the server function.
If I play the playlist, it will be sended to the smartphone.
After, I have to choose the player. It is the renderer function.
If I select the Chord Poly, the Poly will play.
If I select USBaudioPlayer PRO, The smartphone will use the USB output of the smartphone.
