The **Send Downlink** widget allows users to manually transmit messages **from the network to the device**.

## What this section does:

It enables remote control or configuration of a LoRaWAN device by sending custom payloads.

## Input fields explained:

- **Confirm Downlinks**: When checked, the network expects an acknowledgment (ACK) from the device.
- **FPort**: Application port (1–223) used by the device to distinguish message types.
- **Payload**: Hexadecimal data to send to the device (e.g., a command or configuration).
- **Valid Duration (seconds)**: How long the message is valid to stay queued before expiring.

## Buttons:

- **Clear Downlink Queue**: Deletes all pending downlink messages for the device.
- **Send Downlink**: Queues the downlink message for the next available transmission slot.

This tool is typically used for testing or managing devices remotely, such as triggering actions, rebooting, or changing config settings
