# 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!
