The default value depends on the targeted group that uses this software. I was thinking of research and development here. The explicit request is the best option - full agreement. However, I wanted to be minimally invasive in my initial contributions and I didn't want to make offensive changes to the method signatures with possibly unexpected side effects. (Apparently this single line change was already too much either. https://osmocom.org/issues/4383 Sorry for that.) I'm happy to prepare a version with parameters, soon. -- To view, visit https://gerrit.osmocom.org/c/pysim/+/23632 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: pysim Gerrit-Branch: master Gerrit-Change-Id: Ie9040c6b127c268878a0845ed73d0918ec6bbb08 Gerrit-Change-Number: 23632 Gerrit-PatchSet: 5 Gerrit-Owner: Robert Falkenberg Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge Gerrit-Comment-Date: Mon, 05 Apr 2021 19:36:55 + Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge Gerrit-MessageType: comment
Change in pysim[master]: Set uSIM to 'type approval operations' in EF['AD']
Hello Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/pysim/+/23632 to look at the new patch set (#5). Change subject: Set uSIM to 'type approval operations' in EF['AD'] .. Set uSIM to 'type approval operations' in EF['AD'] The ``EF_AD`` field contains administrative data (AD). It consists of four bytes ``B1``, ``B2``, ``B3``, ``B4``, and optionally further bytes for future use. Current implementation only sets the MNC field appropriately (located in `B4`) and sets all other bits/bytes to 0. However, `B1` defines the *UE operation mode* as listed below. For type approval operations (such as testing with a test uSIM), this value should be set to `0x80` rather than `0x00`(= normal operation). This may unlock some UE capabilities that are restricted in normal operation mode.
