Jip. I need to make sure that the TCP connection is to be second to my cellular connection to the cloud. If the cellular connection to the cloud is more importand.
So as your said there is a TCP connection to the PLC. When this connection is broken than the cellular connection to the cloud is negatively effected. What makes it worse is that once that connection to cloud is broken the OTA upload also do not work anymore and the system is dead in the water.
