Re: PDU - cdr format

[jacob]

The message debug block will print the hex representation of the uniform vector data. If you want to print a string from this data you will need to do some translation. If you are on 3.10 you can use the now in-tree PDU Lambda block to do this with the following lambda function:

lambda x: print(str(print(''.join(chr(v) for v in x))))

Hi Jacob,

Assuming that data are encoded text values how to print it as a test using Message Debug block? My goal is to print the data in the console.

A PDU is a special type of PMT pair object that consists of a PMT Dictionary (of metadata) and a PMT Uniform Vector (of data). This is defined as such to make operating on PDU type data somewhat standardized.

Depending on what you are actually trying to do you have a few options. If the string is metadata you can add it to the PMT metadata dictionary; if the string _is_ the data, you can save the encoded text values as a U8 uniform vector.

Hi Community,

Does the cdr part of the PDU has to be a PMT uniform vector? What if I want to fill the cdr with string type of data?
