ELV MAX! mit RFM69cw

[thomas.dunkel]

Hallo zusammen,

ich versuche seid einiger Zeit meinen RPi mit einem RFM69cw die ELV MAX! Sprache beizubringen. Dank eines Posts von Ulli über HomeMatic und einem RFM69 hier im Forum (siehe Link unten) ist mir dies auch gelungen. Mit einem MAX! Cube empfange ich bei der Suche nach einem neuen Gerät leider nur unverständliche Zeichen (auch nach Dewhitening mit PN9 Sequenz und/oder XOr-Entschlüsselung) und diese auch äußerst sporadisch. Außerdem vermute ich, dass meine RFM69cw-Konfiguration nicht korrekt ist. Wenn ich diese so anpassen, wie im Code von CUL für ELV MAX! (vgl. rf_moritz.c) angegeben, dann empfange ich nichts mehr.

Weiß jemand, wieso ich lediglich sehr sporadisch Signale und falsche Daten empfange bzw. wo mein Fehler in der Konfiguration des RFM60cw liegt?

Vielen Dank!
