Hi Sanmi,

This code is still in the development stage, we are not supporting it until it is officially released. There are still some issues that need to be taken care of, and if you're looking at the in-band code in the trunk it's months old.

However, this is mainly a PMT question. The second parameter is used to return the number of bytes in the uniform vector. It is not how many bytes you want to read, it is how many bytes were read.

The variable is is used in: <const void *samples =
pmt_uniform_vector_elements(pmt_nth(2, data), n_bytes);> which is used to
define the data length.

When I printed the <n_bytes> variable, I noticed it took *random values on my

Is my observation correct, or is something done elsewhere?
