# subghz

Sub-GHz communication.

This module allows interaction with Sub-GHz frequencies for reading and transmitting data.

### Example

```js
const subghz = require("subghz");

// Set frequency to 433 MHz
subghz.setFrequency(433);

// Read incoming signal for 5 seconds
const receivedData = subghz.read(5);
console.log("Received Data:", receivedData);

// Transmit a stored signal file
const success = subghz.transmitFile("/plug1_on.sub");
if (success) {
  console.log("Transmission successful!");
}
```
