Attribute could not be set

[baverozceylan]

When I tried to run lorawan-example.cc file, I get following error message;

"Attribute name=NbRep could not be set for this object: tid=ns3::LoRaWANNetDevice"

I think the program tries to set the NbReb attribute to an invalid value.

How can I fix that ?

Note that lorawan-example-tracing was primarily used during the final de of the module. The other examples are older. That said, you could try setting nbrep via lorawanhelper: lorawanHelper.SetNbRep (1);

By default, lorawan-example doesn't touch nbrep though. So most likely you are experiencing a bug. I don't have access to a computer to troubleshoot however(posting this from mobile).

Dear all,

I confirm that the bug exists:

https://github.com/imec-idlab/ns-3-dev-git.git in the lorawan branch, commit 0b80ed111ea64c8f473366500534a02ff4d9b284, I run the following:
