# RTL8720DN Driver
This package provides a driver to use a separate connected WiFi processor `RTL8720DN` for TCP/UDP communication.
At this time, only part of TCP is supported.
## Using th RTL8720DN Driver
For now, it is only available for the `RTL8720DN` on `Wio Terminal`.
You can try the following command.
```
$ tinygo flash --target wioterminal --size short ./examples/rtl8720dn/webclient/
$ tinygo flash --target wioterminal --size short ./examples/rtl8720dn/tlsclient/
```
## RTL8720DN Firmware
Follow the steps below to update.
The firmware must be version 2.1.2 or later.
