IR Receive, Send + Webservice Call

[Terra]

Hallo Leute,

Ich versuche jetzt seit ein paar Tagen meinem NanoESP folgendes beizubringen:

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)

Das ganze funktioniert getrennt schon sehr gut, ich habe ein Script das bei dreimal drücken der taste “TV” auf meiner Fernbedienung 3x das Signal zum Beamer ausschalten sendet und einmal ein weiteres Script das beim starten den WebService Call an den Yamaha AV Receiver schickt. Beides funktioniert unabhängig tadellos.

Jetzt habe ich die beiden Scripts in ein Script gepackt und der WebService Call geht leider nicht, ich bekomme immer eine Fehlermeldung des NanoESP das der Call nicht geschickt werden kann.
Ich vermute das der Speicher zu klein wird obwohl die GUI nichts anzeigt :/

Ich hab schon überall probiert Speicher zu sparen, aber ich denke das Problem liegt an dem langen String den ich über den WebService schicken muss. Kann ich den irgendwie Speicherschonender zusammenbauen und übergeben?

Relevanter Teil:

#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>"

  String getRequest = "POST "+Subpage+" HTTP/1.1\r\nHost:"+Host+"\r\nContent-Type: text/xml;charset=\"UTF-8\"\r\nAccept: text/xml\r\nContent-Length: " + String(strlen(AVRStopMessage)+1) + "\r\n\r\n" + String(AVRStopMessage) + "\r\n";

  sendCom("AT+CIPSTART=\"TCP\",\""+Host+"\",80", "OK");
  sendCom("AT+CIPSEND=" + String(getRequest.length() + 2), ">");
  esp8266.println(getRequest);

Das ganze Script:

#define SSID "*****"
#define PASSWORD "*****"

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.

Hi, ich programmiere auch gerade ein IR Modul und möchte meinen Yamaha Receiver steuern. Der Code 0x7E8154AB ist ja für Power. Wie hast du diesen Code ermittelt bzw. wo hast du diesen Code gefunden? Ich suche bislang vergeblich nach den Codes der gesamten RV300 Fernbedienung.
Viele Grüße
Puuh
