I'm having troubles with the cellular network on my smart controller.
I'm using the only dongle that should be supported, APN is correct but I don't get any internet-connection.
when I put the dongle in my laptop, mobile router or anything else, it works perfectly, only on the controller it doesn't work.
the blue light flashes, pin-code is disabled.
