Re: [Discuss-gnuradio] Pre-cog Simple MAC Error

[John Malsbury]

I haven't seen that before.  Not sure if this is the problem, but what happens if you put a throttle on the ourput of the file source and set it to some unreasonably low rate? 

Also, are you running gnuradio 3.6.5?

Hello 

I am using the Pre-cog library for sending a simple data file from one usrp N210 to another USRP N210. I have replaced the TCP Block with a file source and a stream to blob block in the GRC. 

When I disable the ARQ, I get the following error. 

Uhandler caught exception: in method 'gr_block_gw_message_type_work_args_return_value_set', argument 2 of type 'int'

I have attached the python script with this email.
