# 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.
