TCP Client communication - Elfin EW11

[jozefnad]

Hello, I try to use Elfin EW11 as Tcp Client and I have node js Tcp server.

I am able to receive and decode messages properly, but when I try to send some message ( socket.write()) nothing happened. Elfin receive that message but I do not know if it is send to Balboa properly or what heppens.

I saw just you to use the EW11 to communicate with balboa, so you can maybe help me.

Do you have any advice how to send message from tcp server to elfin tcp client to communicate with spa?

Thanks so much.
