DKVbrowser 2.05 will not connect to my piano.

[Brian Weston]

Hi.  I am not able to get DKVbrowser to connect to my MarkIV.
It used to work perfectly for years.
Now when I start up DKVbroswer  it finds my piano on the network,

it then says it it connecting....

it then says Connected to <my piano/IP address> awaiting...

And it never gets past this point.

Does anyone know what the next step it is trying to perform?

I am having the same issue with the ControllerUS app on my iphone.  

it is able to see the piano on the network.

I click to connect and it says connecting but never gets past this point.

Yamaha support is not very helpful.  They keep telling me to uninstall the app and reinstall.  This does not help.

If someone can suggest what DKVbrowser is trying to do when it gets to the "awaiting..." status it might be helpful to pass on to support.   

Thank you in advance!

Brian,

I found a similar problem, after years of trouble free connection to my Enspire.

Firstly, get your controlling device (iPad or phone) close to the piano.

Go into the 'Settings' preferences in your device and turn Off Wi-Fi

House Wi-Fi will no longer show and beside the Wi-Fi symbol, it will read 'Off'

Now turn On the Wi-Fi switch.

House Wi-Fi will pop up again, automatically, but wait 10 seconds and you will see DKV************* appear among the My Networks alternatives

Click on that and it will shown as the Network now operating.

This should allow you to Proceed as usual – in my case opening the EN app to access control.

Brian,

DKVBrowser's handshake with the piano goes something like this (from memory):

a) Find the piano on the network (this uses a combination of a saved IP from the last time it worked, in combination with network plug and play [the piano announces itself periodically], and, if all else fails, DKVBrowser allows you to type in a hostname/IPAddress.  You are clearly getting through this step.

b) Logon to the piano.  This is an encrypted step where the client says it wants to log in, the piano offers up a challenge, and the client must respond with a key to unlock the door.  Once that happens, you are mostly there, and DKVBrowser should mostly appear to be done with connecting.  (I think you are stuck here).

c) Only after b is successful does the piano allow connection to the internal database.  At this point, DKVBrowser can start populating the screen with albums/songs.  I've seen cases where DKVBrowser gets through a & b, but appears "empty", indicating things failed here at "c".  (I don't think you are making it this far.)

The fact that the app on your phone is failing as well gives me plenty of confidence to say that there's nothing wrong with DKVBrowser here.  My first suggestion, if you haven't already tried it, is a hard power down of the piano.  I've learned that all sorts of gremlins creep into this old software if it is left running for too long.  If that doesn't work, I could work with you offline to see *precisely* which step isn't working, but even with that information, it isn't clear what the next step would be since Yamaha support remains mostly clueless at this level.
