[Discuss-gnuradio] Error with wifi_tx and wifi_transceiver

[Rafik ZITOUNI]

Hi, 

I am using gnuradio in a second machine where I had installed gnuradio version 3.7.12git-126-g37d373ac. 

I tried to run wifi_tx and wifi_transceiver and I obtained the following error: 

    tb = top_block_cls()

  File "/home/rafik/Workspace/gr-ieee802-11-next/examples/wifi_tx.py", line 153, in __init__

    sensitivity=0.56,

  File "/home/rafik/.grc_gnuradio/wifi_phy_hier.py", line 81, in __init__

    self.msg_connect((self.ieee802_11_decode_mac_0, 'out'), (self, 'mac_out'))

  File "/opt/usr/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 59, in wrappe

mitive_msg_connect

    return _runtime_swig.hier_block2_sptr_primitive_msg_connect(self, *args)

RuntimeError: invalid msg port in connect() or disconnect()

Do you have an idea how to fix this error. 

Best,
