Patch Set 2: (3 comments) File pySim/commands.py: https://gerrit.osmocom.org/c/pysim/+/34846/comment/6e5fcbd2_098448ac PS2, Line 42: if cla >> 4 in [0x0, 0xA, 0x8]: I find this a bit difficult to read. Maybe cla & 0xF0 in [0x00, 0x0A, 0x80] is better. Also I am a bit lost here. The positions of the logical channel match ISO/IEC 7816, section 5.1.1 but 0xA0 and 0x80 are proprietary classes that are not encoded as per ISO/IEC 7816? Maybe a spec reference would help? https://gerrit.osmocom.org/c/pysim/+/34846/comment/0701763c_40903ebc PS2, Line 93: if not cla: the caller must decide when to access the cache and when not? https://gerrit.osmocom.org/c/pysim/+/34846/comment/c4f8e6be_6324b2ab PS2, Line 526: return self._tp.send_apdu_checksw(self.cla_byte + self.cla4lchan('e0') + '0000%02x%s' % (len(payload)//2, payload)) Does this work? The class is E0 but E0 >> 4 is not in [0x0, 0xA, 0x8] (line 42) -- To view, visit https://gerrit.osmocom.org/c/pysim/+/34846?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: pysim Gerrit-Branch: master Gerrit-Change-Id: Ibe5650dedc0f7681acf82018a86f83377ba81d30 Gerrit-Change-Number: 34846 Gerrit-PatchSet: 2 Gerrit-Owner: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Tue, 24 Oct 2023 10:29:15 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
