5 years ago you should run "authorize"again to debit session. you can change debit number param in this class https://github.com/Emotiv/cortex-v2-example/blob/master/csharp/CortexAccess/Config.cs may 100 - 200. you will not need run "authorize" many times (default value is 5)
Hi everybody, I need to use the Cortex V2.0 with the examples presented on C# but it didn't work and I always get this error "MessageErrorRecieved :code -32019 message Session limit on this device has been reached." I have a free license and it does this error on all examples. I only use an Epoc+ headset.
If you have any clue about this please tell me, Thanks in advance.
I am pasting the console output showing the JSON messages exchange:
