( https://gerrit.osmocom.org/9575 Change subject: __init__: also fetch response bytes for USIMs automatically ...................................................................... __init__: also fetch response bytes for USIMs automatically The method send_apdu() first transmits the APDU in the cards direction. The card may indicate that there is a response available by responding with SW1=9F, where SW2 is the number of bytes. send_apdu() will then craft a get-response APDU to pickup the response bytes. This mechanism works fine for SIM, but USIM uses SW1=61 to indicate the availability of a response, so lets also sense on SW1=61 to support USIMs as well. - Also check on SW1=61 to see if a response is available Change-Id: Ied7fb78873a7c4109de471c7a5e9c3701ba0c7d5 Related: OS#4245 --- M pySim/transport/__init__.py 1 file changed, 7 insertions(+), 1 deletion(-) git pull ssh://gerrit.osmocom.org:29418/pysim refs/changes/75/9575/1 diff --git a/pySim/transport/__init__.py b/pySim/transport/__init__.py index dd04bba..158b906 100644 --- a/pySim/transport/__init__.py +++ b/pySim/transport/__init__.py @@ -67,7 +67,13 @@ """ data, sw = self.send_apdu_raw(pdu) - if (sw is not None) and (sw[0:2] == '9f'): + # When whe have sent the first APDU, the SW may indicate that there are response bytes + # available.
