Patch Set 8: (1 comment) File include/osmocom/gsm/bts_features.h: https://gerrit.osmocom.org/c/libosmocore/+/31415/comment/dfc81cd8_142911f5 PS7, Line 39: _TX
In a correctly configured setup we should always see the same format in both directions.
If you say so... I don't think that's really stated anywhere in the spec, and sounds like a personal expectancy of what a "correctly configured setup" is imho 😊
I thought the OML feature flags were introduced for things like this
Yes, to know that a BTS supports a given feature. Not to indicate which of the several supported is to be used.
BTS model is a PHY based model with TS 101318 support or an osmo-trx based model with RFC 5993 support.
So our osmo-bts-sysmo is transmitting different RTP type than our osmo-bts-trx? what a mess! 😮
The BSC knows that it talks to an osmo-bts, but it does not know if this BTS model
My point is only that you still need to store that in osmo-bsc hardcoded somehow for other types of BTS, like nanobts, etc. so you could simply do the same for osmobts (you will need this for older versions of osmo-bts anyway). Maybe that's actually done using this set of features?

Extending IPACC can be also a way, here we can at least be sure that osmo-bts type BTSs will support the extension but we will have to make sure that older osmo-bts versions will tolerate/ignore the extensions.
Yes, have a look if adding the new IE is really a problem for old versions (I think it won't be an issue). If it was, then you could add a new BTS feature stating whether the BTS supports this new IE and then only send it based on it. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/31415 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I05e4ed7a85f3a0451de7cd07380503a7ac76d043 Gerrit-Change-Number: 31415 Gerrit-PatchSet: 8 Gerrit-Owner: dexter <pmaier@sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy@sysmocom.de> Gerrit-Reviewer: laforge <laforge@osmocom.org> Gerrit-Reviewer: msuraev <msuraev@sysmocom.de> Gerrit-CC: neels <nhofmeyr@sysmocom.de> Gerrit-CC: pespin <pespin@sysmocom.de> Gerrit-Attention: neels <nhofmeyr@sysmocom.de> Gerrit-Attention: fixeria <vyanitskiy@sysmocom.de> Gerrit-Attention: msuraev <msuraev@sysmocom.de> Gerrit-Attention: dexter <pmaier@sysmocom.de> Gerrit-Comment-Date: Tue, 28 Feb 2023 13:33:25 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: neels <nhofmeyr@sysmocom.de> Comment-In-Reply-To: pespin <pespin@sysmocom.de> Comment-In-Reply-To: fixeria <vyanitskiy@sysmocom.de> Comment-In-Reply-To: msuraev <msuraev@sysmocom.de> Comment-In-Reply-To: dexter <pmaier@sysmocom.de> Gerrit-MessageType: comment
