Re: C++ OOT module vector size does not match

[Huang Wei]

Problem solved, I need to add in the yml file "vlen: 1024 " for both inputs and outputs.

Hello group,

I am writing a C++ OOT module in GNU radio operating in vectors of length 1024. So in the .cc file I wrote:

      gr::io_signature::make(1, 1, sizeof(float)*1024),
      gr::io_signature::make(1, 1, sizeof(float)*1024)),

And in the work function I wrote:

      float *out = (float *) output_items[0];
      int noi = 1024 * noutput_items;

      memcpy(out, input_items[0], noi * sizeof(float)); // just copy input to output
      return noutput_items;

when I connect a "Stream to Vector" block (Num of items=1024, Vec length =1) to this custom block, it shows "Source IO size 4096 does not match sink IO size 4".

Where did I make the mistake? noutput_items indicates the num of output vectors, right? 

Thank you if you could give me any help.

Regards,

Wei
