I assume this setup is part of a very old experiment that you want to reboot. However, something must have changed since it's broken at the moment. It is very difficult to spot the issue without any context but just a traceback. The message itself tells you that you try to connect a message port that's not an actual message port. GRC generates a Python file for your flowgraph. In your case you also have a hier block that receives a second Python file. The error happens in there: self.msg_connect((self, 'time_per_angle_message'), (self.theomodule_set_array_and_tt_RX_0, 'time_per_angle_message')) This hier block is potentially called "RX_SC_PHY". You might want to check what happened there.

Hey everybody,
I am currently facing the following error:
Could not find port: time_per_angle_message in:
system
Traceback (most recent call last):

     main()

     tb = top_block_cls()

     usrp_tx_address="addr=192.168.10.4",
   File "/home/theow/.grc_gnuradio/phy_transceiver.py", line 90, in __init__
     threshold=detector_threshold,
   File "/home/theow/.grc_gnuradio/RX_SC_PHY.py", line 91, in __init__

     self.primitive_msg_connect(*args)

RuntimeError: invalid msg port in connect() or disconnect()
I googled a lot, but I did not really find an answer to that problem...

Thanks in advance,
Theo

I know for sure, that this setup was already working...so I am even more confused about that error. Would be very great if anyone had maybe a quick idea, how to solve this error. If you need any more information, I will gladly provide it.
