Issue Description

Hi, I am using the latest version of srsRAN release_24_04 and I am having problems with the FlexRIC monitoring xApp. The RIC execution stops as soon as I launch the app with the following error:
nearRT-RIC: /home/vscode/flexric/src/sm/kpm_sm/kpm_sm_v02.03/dec/kpm_dec_asn.c:184: kpm_dec_ind_msg_asn: Assertion `rval.code == RC_OK && "Are you sending data in ATS_ALIGNED_BASIC_PER syntax?"' failed.

What commit are you using from the br-flexric branch? I don't know if I'm using a different one that is not compatible.

I was previously using srsRAN version 23_05 and had no problem with this.

Setup Details

FlexRIC branch br-flexric last commit
srsRAN Project last release
srsRAN 4G UE
Open5Gs core

Expected Behavior

The monitoring xApp obtains the data.

Actual Behaviour

The RIC execution stops as soon as I launch the app with the following error:
nearRT-RIC: /home/vscode/flexric/src/sm/kpm_sm/kpm_sm_v02.03/dec/kpm_dec_asn.c:184: kpm_dec_ind_msg_asn: Assertion `rval.code == RC_OK && "Are you sending data in ATS_ALIGNED_BASIC_PER syntax?"' failed.

Hi @apperezG,

Please check the documentation as it has been updated recently. You can find the tutorial relating to the use of nRT RICs here.

From the documentation you will see that you need to use commit: 1a3903a7 from br-flexric.

Please re-try while following the latest documentation.

Hi @brendan-mcauliffe,
I am testing with that specific commit and with srsRAN version 24_04 (following the guide exactly) and still the xapp_oran_moni is not working, giving the same error.
I am using the configuration files you provide.

Hi @brendan-mcauliffe,
I also tried with the commit 0b2702c (the one used in the guide) of srsRAN Project but it gives me the same error:
"kpm_dec_ind_hdr_asn: Assertion `rval.code == RC_OK && "Are you sending data in ATS_ALIGNED_BASIC_PER syntax?"' failed."

@apperezG could you check if this solution (a patch that removes granul_period from the RIC indication message) works for you?
