I'm struggling with PyObject_CallMethod trying to send unsigned char * to python script, but it gives me error calling the method on the python side. I've tried s,s#,s*,y and B formats but with no luck. which format should I use?
Here's the reference I'm looking at https://docs.python.org/3/c-api/arg.html#c.Py_BuildValue
I found the solution!
I had to memcpy the unsigned char * with known size to unsigned char[KNOWN_SIZE] and then send it based on this link: https://docs.python.org/3/c-api/arg.html , I had to send the array with this flag 's#' where s refers to the type of the type of the first parameter and # is the size of the first parameter.
