Connection with multiroom audio E6g by network

[Frank VDD]

Hello,

I'm trying to connect to a multiroom audio system: NUVO E6G. Therefor, i use a serial over TCP/IP converter (UDS10).
I wrote some code in VB2010 and it works fine. I can switch a zone on or off, decreasing or increasing the volume etc.
I would like to do the same with my MEDION Tablet(Android 4.1).So i started coding in B4A.
In the attachement you can find the code. If i sniffer with wireshark, i can see, it sends the command "*ALLOFF" but the multiroom doesn't react on it.
I'm sure, i do something wrong with network library, but i don't see what exactly.
Can someone give me a tip? Many thanks
Greetings
Frank

How is the command terminated? With an end of line character?

 

[Frank VDD]

Every command must begin with "*" and end with Carriage Return

This example will request the version information from the NuVo Main Processor Unit:
CMD *VER<CR> : command
RSP #VER"NV-I8G FWv0.91 HWv0"<CR><LF>: response

I haven't downloaded your project. However make sure that you are ending each command with:
Chr(13) & Chr(10)

CRLF constant = Chr(10)

i've tried it this morning. It worked, by adding Chr(13)&chr(10) after the command instead of CRLF.
The "CRLF" in vb2010 is apparantly different from the one in B4a. The resolution was very simple but you have to know the resolution
Many thanks for the assistance
