# Connect your LoRaWAN device and verify its connection status
Before you can check the device connection status, you must have already added your device and connected it to AWS IoT Core for LoRaWAN. For information about how to add your device, see [Add your wireless device to AWS IoT Core for LoRaWAN](lorawan-end-devices-add.md).
After you've added your device, refer to your device's user manual to learn how to initiate sending an uplink message from your LoRaWAN device.
## Wireless device destination payload
The following code shows the payload received at the destination for your wireless device. It shows a sample payload when using your own private LoRaWAN gateway, and when you use a public network. It also shows the payload format if you exclude the gateway metadata information. The following shows a sample payload.
```
HTTP/1.1 200
Content-type: application/json
{

}
],

}
```
### Payload example with private LoRaWAN gateway
This example uses a private LoRaWAN gateway to show the gateway metadata information in the uplink message. The metadata consists of the gateway EUI, SNR (signal to noise ratio), and RSSI (Received signal to strength indicator). These values can help you determine the strength of your gateway channel and whether to switch to a stronger channel.

}

}
```
### Payload example with public network
You can also connect to the public network instead of your own private LoRaWAN gateway. The public network is provided and operated as a service directly by Everynet. The following example shows the public LoRaWAN network metadata in the message. The metadata consists of the ID of the gateway and the network provider (Everynet), whether downlink is allowed, and the SNR and RSSI values. For more infrrmation about the public network, see [Managing LoRaWAN traffic from public networks (Everynet)](iot-lorawan-roaming.md).
**Note**
The uplink message will mention `PublicGateways` to indicate that it's received from the public network and not a private LoRaWAN gateway.

### Payload example without gateway metadata
If you want to exclude the gateway metadata information from your uplink metadata, disable the **AddGwMetadata** parameter when you create the service profile. For information about disabling this parameter, see [Add service profiles](lorawan-define-profiles.md#lorawan-service-profiles).
In this case, you won't see the `Gateways` section in the uplink metadata, as illustrated in the following example.
```

## Check device connection status
The following sections show you how to check the connection status using the AWS Management Console and the AWS CLI.
### Check device connection status using the console
To check the connection status using the console, navigate to the [https://console.aws.amazon.com/iot/home#/wireless/devices](https://console.aws.amazon.com/iot/home#/wireless/devices) page of the AWS IoT console and choose the device you've added. In the **Details** section of the Wireless devices details page, you'll see the date and time the last uplink was received.
### Check device connection status using the API
To check the connection status using the API, use the [`GetWirelessDeviceStatistics` API](https://docs.aws.amazon.com/iot-wireless/latest/apireference/API_GetWirelessDeviceStatistics.html). This API doesn't have a request body and only contains a response body that shows when the last uplink was received. The response from the API also indicates whether it's received from a public network or a private LoRaWAN gateway.
## Next steps
Now that you have connected your device and verified the connection status, you can observe the format of the uplink metadata recieved from the device by using the [ MQTT test client](https://console.aws.amazon.com/iot/home#/test) on the **Test** page of the AWS IoT console. For more information, see [View format of uplink messages sent from LoRaWAN devices](lorawan-uplink-metadata-format.md).
