The meaning of each LED color and blinking pattern is described below:

| <mark style="color:blue;">**Blue – quickly blinking**</mark>     | The gateway is connected to the mobile app and ready for configuration.                |
| ---------------------------------------------------------------- | -------------------------------------------------------------------------------------- |
| <mark style="color:blue;">**Blue – slowly blinking**</mark>      | The gateway is searching for an LTE signal and initiating communication.               |
| <mark style="color:blue;">**Blue – constant**</mark>             | The gateway is connected to an LTE network.                                            |
