Keine Antwort auf StatusEnquiry

[pc-coholic]

Servus!

Ich bin in ein Problem reingelaufen, bei dem ich aktuell noch keinen Ansatz habe das erfolgreich zu umgehen.

Es wird das test_pt.py ausgeführt, bei der Aufforderung die Karte einzugeben allerdings am Terminal auf Abbrechen gedrückt.

Anscheinend liefert dann bei einem folgenden StatusEnquiry das Terminal (ein Ingenico i5310+LAN) keine Antwort zurück.

Gibt es denn eine einfache Möglichkeit wenn ein StatusEnquiry fehlschlägt das einfach zu ignorieren und nach einigen Sekunden es nochmals zu probieren?

[g4borg]

mhm, bevor ich was zu der frage selbst was sagen kann, die transport-layer-exception (unknown ack-byte) tritt dann genau in diesem falle auf?
oder ist das einfach wegen dem time-out?

[g4borg]

man kann den fehler zumindest probieren abzufangen, und dann transmission.is_master auf True setzen, sowie is_waiting auf False - das wäre zumindest die hardcore variante. Ob das Terminal darauf reagiert weiss ich nicht.

Ich wundere mich jedoch, was eigentlich hier schief läuft.

[g4borg]

Ich sehe gerade, das is_master wird auch vor dem re-raise des Fehlers gemacht.
ein auskommentieren des wait_for_status() in zeile 40 sollte das senden des StatusEnquirys jedoch komplett überspringen, sobald man abbrechen drückt.
