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.

same for me

Same here, works on my PC. No data when moved to the controller...not ideal for a supported model.

Any solution for this?
