Also, you need a throttle between your file source and UDO sink or you will try to send as fast as the file can read (which is almost certainly faster than your network. And, high speed network I/O generally requires some kernel tuning. Sent from my iPhone > On Jul 4, 2023, at 3:57 AM, Marcu

Convert PDU message to a PMT message

2023-07-05 Thread Barry Duggan
I would like to receive a PDU message containing a string using an Embedded Python Block and, after discarding certain messages, send a PMT message with that string to the output message port. My efforts so far have not produced a valid PMT format. My current code is: ``` import numpy as np f
