Wio LTE TCP Server


I am trying to send data from my Web server to a Wio LTE Cat.1. Meaning, I need Wio LTE to operate as a TCP server (but I cannot find how to do that).
As there are no examples of how to receive data (only how to send) to a Web server, is there anyone out there who could help me and literally save my day?
Thank you very, very much in advance!

I have found it myself…sending a TCP LISTENER command with the IP of Wio solves the problem.
