I try to use the package Synchrophsor package in Python to connect with the OpenPDC. However, I meet some problems that the progress appears Received unknown messages. Could you tell me how to develop the progress to solve this Problem.
Looks like the package is having trouble parsing the header packet. Since this packet it technically free-form (according to the standard), I am not sure what format the package is expecting. Perhaps it is expecting the header frame contents to be in XML. In the case of the openPDC, it just returns some basic information about the connection in text format.
The header frame is rarely required though, perhaps you can skip header frame parsing and move on to config and data frames?
