PJLINK

[Roy]

Hello,

I'm trying to control a projector with PJLINK protocol without password needed. 

This protocol is very used, I think, and maybe some user can help me.

http://pjlink.jbmia.or.jp/english/

First I test comunication and commands with Hercules and everything works. But I see that I need to reconnect all the time because projector close the conecction after I send a command.

In guiDesigner I created a TCP client system, use connected Join to see if iViewer are connect and add (.*) feedback to see messages from the projector.

In iPad side I see connected Join ON, but nothing in text filed with (.*) feedback and commands don't works.

I try heartbeat to keep connection open (maybe never was opened...), but don't works.

I think I have a connection trouble because I never receive "PJLINK 0" (see picture)

Please help and apologies for my bad English

Regards

Your "end of message" should be \x0D. We dont support 0x0D notation.

Also, make sure your heartbeat commands have \x0D on the end too. The End of message character is not automatically appended to outgoing data, it is only used to split up incoming packets.

Thank you, Jarrod.

As usual, you are right. 

Now everything works fine.

Best regards.
