# micropython ESP32 UART to TCP bridge

A micropython server running on an ESP32 which acts as a bridge

between UART and TCP (LAN/WLAN).

## Installation

Follow steps to install *esptool* and *micropython for ESP32*.

Then...

* clone me, oh please, clone me!

```bash

$ git clone [email protected]/tiagocoutinho/us2n

```

* Create a file called `us2n.json` with a json configuration:

```python

import json

config = {

    "name": "SuperESP32",

    "verbose": False,

    "wlan": {

        "sta": {

            "essid": "",

            "password": "",

        },

    },

    "bridges": [

        {

            "tcp": {

                "bind": ["", 8000],

            },

            "uart": {

                "port": 1,

                "baudrate": 9600,

                "bits": 8,

                "parity": None,

                "stop": 1,

            },

        },

    ],

}

with open('us2n.json', 'w') as f:

    json.dump(config, f)

```

* Include in your `main.py`:

```python

import us2n

server = us2n.server()

server.serve_forever()

```

* Load the newly created `us2n.json` to your ESP32

* Load `us2n.py` to your ESP32

* Load `main.py` to your ESP32

* Press reset

The server board should be ready to accept requests in a few seconds.

## Usage

Now, if, for example, your ESP32 UART is connected to a SCPI device,

you can, from any PC:

```bash

$ nc  8000

*IDN?

ACME Instruments, C4, 122393-2, 10-0-1

```

That's all folks!
