I recently installed MQX 4.0.2 for my kinetis k70.
So far I have used MQX 4.0
Unfortunately I'm experiencing an anomaly for the library RTCS.
In my project I connect as a client to a remote server(AMAZON) using sockets.
Until now, I never had problems, but on some connections made with different modem, I can not connect via "connect".
I was able to verify that the hardware is working, by installing MQX 4.0.
Not being an expert on networks, I wonder if there were any configurations to be done.
