Hi,
I am trying to get the LoRaWAN test project running using the Nucleo-L073RZ and I-NUCLEO-LRWAN1. However, the official STM example does not transmit. Can you help me figure out the issue?

The I-NUCLEO-LRWAN1 is obsolete:
It's likely that both the ST examples and the networks have moved on ...

What have you done so far?
Have you looked at the UART logs?

I fixed the UART, and the project is now active. It logs correctly, but the LoRa module does not physically transmit, and I can't figure out what the error is.

The UART output should show you what the code is doing - and where it's failing.

I am using this project "STM32CubeExpansion_LRWAN_V2.1.0->Projects\NUCLEO-L073RZ->Applications->LoRaWAN->LoRaWAN_End_Nod->STM32CubeIDE->sx1272mb2da" and it is log

So your join is failing.
Are you sure your credentials are all correct, frequencies correct, and your network supports the join type you're using?
It's better to post console output as text:

Everything is fine, it just doesn't transmit.

How do you know it doesn't transmit?
It says it does ...

I am monitoring the gateway log and using other receivers to try to capture the moment when the transmission occurs.

Perhaps try sniffing the AT Commands & responses between the Nucleo-L073RZ and the I-NUCLEO-LRWAN1 ?
