Antwort auf: IR Receive, Send + Webservice Call
Ich hab den Fehler inzwischen gefunden, es war wie vermutet die Variable/Konstante:
#define AVRStopMessage „<?xml version=\“1.0\“ encoding=\“utf-8\“?><YAMAHA_AV cmd=\“PUT\“><Main_Zone><Power_Control><Power>Standby</Power></Power_Control></Main_Zone></YAMAHA_AV>“
Wenn ich die Zeichenkette im obigen Programm reduziere schickt er den Webservice Call, ansonsten nicht.
Ich hab jetzt nochmal ein paar debug ausgaben verkürzt, HTTP Header entfernt und ein paar Sachen anders gelöst oder gelöscht, jetzt klappt alles :)
WENN:
– Ich 3x die “TV” Taste meiner Fernbedienung drücke
DANN:
– Soll sich mein Beamer ausschalten (durch 3x dasselbe IR Signal senden)
– Mein Yamaha AV-Receiver ausschalten (durch Webservice Call auf lokale IP)
– Zusätzlich blinkt eine LED bei jedem IR Signal das er empfängt, nur damit ich sehe ob er noch zuhört.

- AVROutputHDMI1 the outputs of the Yamaha must be set via the NAMES that were assigned in

"HTPC" is hardcoded in the request!
All of the extra ones are disabled because of space issues...
