Fehler beim Empfang über wmbus - tty buffersize

[ert77]

Hallo zusammen,
ich habe einen nanoCul 868 von smart-home-komponente.de mit einer für wmbus angepassten Firmware.
Damit möchte ich einen WMZ Sensostar 2 U auslesen.
Der WMZ sendet im CMODE. Die Verschlüsselung ist ausgeschaltet.
Es kommen, wie unten zu sehen, auch Daten an, aber es kommt immer eine Fehlermeldung:
WMBUS Error during LinkLayer parse:message too short, expected 160, got 148 bytes

Scheinbar hat der nanocul einen 300byte Buffer.

Könnt Ihr mir sagen, wie ich das Problem lösen kann?
Leider bin ich in Sachen FHEM, nanCul und wmbus noch sehr unerfahren.

nanoCUL_r568_mbus_c1t1_bufsize300Auf dem nanocul ist demnach eine spezielle Firmware für mbus mit einer TTY_BUFSIZE von 300 drauf.

Please make sure that TTY_BUFSIZE in culfw is at least two times the message length + 1Du benötigst aber eine Firmware mit einer TTY_BUFSIZE von mindestens 321.

Du kannst ja mal bei smart-home-komponente nachfragen.
