# Example: Updater
|
||||
|
||||
A simple example of an updater client wich can:
|
||||
|
||||
- Configure a ReachRS module to use the given WiFi network
|
||||
- Check for updates then reboot to "ReachView" mode
|
||||
|
||||
## Usage
|
||||
|
||||
1. Boot your ReachRS module in "Updater" mode. You can see a documentation on how to reset your device [here](https://forge.cadoles.com/Pyxis/orion/wiki/FlashIt).
|
||||
|
||||
2. Launch the example in `configure-wifi` phase and provides WiFi network informations.
|
||||
```shell
|
||||
go run example/updater/main.go \
|
||||
-phase 'configure-wifi'\
|
||||
-host '<DEVICE_IP_ADDRESS'\
|
||||
-ssid '<WIFI_SSID>'\
|
||||
-password '<WIFI_PASSWORD>'\
|
||||
-security '<WIFI_SECURITY>'
|
||||
```
|
||||
3. The device will switch to the provided WiFi network, as you should do.
|
||||
4. Launch the example in `update-then-reboot` phase.
|
||||
```shell
|
||||
go run example/updater/main.go \
|
||||
-phase 'update-and-reboot'\
|
||||
-host '<DEVICE_IP_ADDRESS'
|
||||
```
