# Raw (TCP/UDP/TLS/DTLS)

Sending a binary content or even strings over UDP/TCP is possible with IoTIFY. The motivation to use a raw protocol could be either to conserve the bandwidth or to support binary formatting of data. There isn't much to specify when using the raw protocols. 

![Settings for Raw Protocol](/files/-M8PerSKoNccl2-RXmqA)

We only need to specify the transport as well as the server endpoint along with the port number. The timeout field is only applicable in case of TCP/TLS/DTLS and specify how long should we wait for connection (as there is no concept of connection in UDP)

### Generating Binary Payload for Raw Protocol

For Raw protocol, you could choose to send a binary payload by returning a buffer Object in the Device Model message function. E.g. 

```
{
    payload = [10,20,44,46]
    
    return new Buffer.from(payload);
}
```

E.g. you could convert a string to base64 representation

```
    let payload = new Buffer('Hello World', 'binary').toString('base64')
    return payload;
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.iotify.io/temp/protocol-settings/raw-tcp-udp-tls-dtls.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
