[Speech to text] Keep alive fails to keep service running

[Naphier]

Unity 2017.3.1f1
Watson Unity SDK 2.0.0
Windows 10 64-bit pro - Unity Editor

Unity Watson SDK - ExampleStreaming scene (no modifications to code)

Expected:
Session doesn't timeout and remains alive.

Actual:
After about 1 minute Session Timeout error occurs. "Sending keep alive" console messages appear, but doesn't seem to help.

Editor log attached.
Editor.log

Current workaround:
I'm just using a coroutine to wait half a second and then restart the service. Not really ideal as there will be periods when the service is off.

Can you see if setting DetectSilence to false helps?

https://github.com/watson-developer-cloud/unity-sdk/blob/develop/Examples/ServiceExamples/Scripts/ExampleStreaming.cs#L63

Trying to narrow down this issue.

Lowering the SilenceThreshold in the same block to 0.001f may also work.

Hello, I also have similar error, but in string
[SpeechToText.OnListenClosed()][DEBUG] OnListenClosed(), State = DISCONNECTED
Can you help?

[mediumTaj]

@Olegjan This is a different issue. Services just switched from TLS 1.0 to TLS 1.2 and the ws library is not liking it. see this issue #330

A hotfix for this will be out soon

hi, is there any other way to keep the session alive with DetectSilence set to true? currently i set InactivityTimeout = -1 and every 20 seconds i will send "highHat" clip with OnListen method and yet i couldn't keep the session alive.

@mediumTaj Was wondering what you would recommend to solve this issue? (error CS0117: System.Security.Authentication.SslProtocols' does not contain a definition for Tls12') If I get rid of the line with Tls12, I end up having the same issue as @Olegjan . Any help would be greatly appreciated.

If using Unity 2018.2 or later you'll need to set Scripting Runtime Version in Build Settings to .NET 4.x equivalent. We need to access security options to enable TLS 1.2.

My Scripting Runtime Version in Build Settings is already set to .NET 4.x but I still get this error message... What am I missing?

Same here, using Unity 2018.3.0f2.
Can't get the samples to work.

I used both https://stream-tls10.watsonplatform.net/speech-to-text/api and https://gateway-lon.watsonplatform.net/speech-to-text/api URLs but it didn't work..

Is this unity-sdk is still maintained ?

[mediumTaj]

@cocapasteque Yes the sdk is still maintained. London endpoint is relatively new. I've had users successfully access it even though we are not explicitly handling it in the SDK. I will patch that up this week though. Are you using .NET 4.x Scripting Runtime?

You can also join our #unity-sdk slack channel in wdc-community: http://wdc-slack-inviter.mybluemix.net/

[cocapasteque]

@mediumTaj Yes of course I'm using .NET 4.x.
Should I use a different endpoint and test with this ?

Gonna join on slack also :)
Thanks for your answer

[cocapasteque]

@mediumTaj Created a new resource located in Washington DC, still not working.
I'm going to try with a older unity version.

@mediumTaj
Working with 2018.2.0f2, didn't worked with 2018.3.0f2. I really have no idea why.

[cocapasteque]

@mediumTaj Last message in this thread for me, found why it wasn't working...
Scripting Runtime was set on .NET 4.x but the Api Compatibility Level was on .NET Standard 2.0, switched it to 4.x and it worked.

You should at this somewhere in your documentation, not only the Scripting runtime should be on .NET 4.x but also the API Compatibility Level. :) Thank you !
