Hi

Please try with versions mentioned in the website: https://flora.aalto.fi/

As far as I remember, there was an update in new inet, and flora is not updated with it.

[Smangaliso1]

Thank you, I'll try and let you know afterwards.

Hi
Thank you initial problem fixed!!!

However, I've also encountered another bug while testing Flora project.

<!> Cannot evaluate parameter 'initialLoRaTP': operator "*": Refusing to perform computations involving quantities with nonlinear units (3dBm) -- in module (inet::SimpleLoRaApp) LoRaNetworkTest.loRaNodes[0].SimpleLoRaApp (id=30), during network setup

[mariuszslabicki]

Could you paste the config file?

[Smangaliso1]

Sorry, config file for Omnetpp or Flora I'm not sure in that case?

[mariuszslabicki]

The .ini file which defines parameters for nodes. If you have run the example simulation from repository, the configuration is set in the "loRaNetworkTest.ini" file.

[Smangaliso1]

Ok, I get you now. below I just copied what is in the file.

Are you sure that this is the config file that is evaluated in your simulation? From the error message: annot evaluate parameter 'initialLoRaTP': operator "*" it seems that the "initialLoRaTP" is not set. But the config file has all parameters configured.

BTW: have you evaluated example simulation?

[Smangaliso1]

Hey,
I managed to fix the error, All was need is to remove this operator "*" from the config files .in.

Thank you.
