Wifi Scan

Scans for wifi networks, returns an array of wifi networks containing the SSID and encryption type

Usage

ubus call onion wifi-scan '{"device":"wlan0"}'

Return

Sample return:

{
	"results": [
		{
			"ssid": "OnionWiFi",
			"encryption": "mixed WPA\/WPA2 PSK (TKIP, CCMP)"
		},
		...
	]
}

Wifi Setup

Ubus interface for the wifisetup application.

Usage

ubus call onion wifi-setup '{"command":"command name", "base64":false, "params":{"argument":"argument value"}'

• command
  • Specifies what operation wifisetup is meant to perform
• base64
  • Specifies if params arguments are base64 encoded
  • Default is false
• params
  • Additional parameter arguments to be passed to wifisetup script

Run wifisetup --help on the Omega to get a better idea of what is available

Example

Connect to network called MyNetwork with PSK2 password that is superduper:

ubus call onion wifi-setup '{"command":"add", "base64":false, "params":{"ssid":"MyNetwork", "auth":"psk2", "password":"superduper"}}'

RGB LED

Sets the colour of the RGB LED on the Expansion Dock using the expled script

Usage

ubus call onion rgb-led '{"command":"<command>", "params":{"colour":"<hex colour value>"}}'

The only available command is set, it will program the RGB LED to the hex colour value found in the params object.

Return

If successfull:

{
	"colour": "<hex colour value>"
}

If not successfull:

{
	"success": False
}

Example

Set the RGB LED to purple:

ubus call onion rgb-led '{"command":"set", "params":{"colour":"0x7700e6"}}'

GPIO

Control the Omega GPIOs.

Implemented using the sysfs gpio interface.

Usage

ubus call onion gpio '{"command":"<command>", "params":{"gpio":"<gpio number>"}}'

Available Commands:

• get
• set
• get-direction
• set-direction
• status

Get Command

Get the current value of the GPIO

Usage:

ubus call onion gpio '{"command":"get", "params":{"gpio":"<gpio number>"}}'

Sample Return:

{
        "success": true,
        "pin": "7",
        "value": "0"
}

Set Command

Set the value of the GPIO (if output direction)

Usage:

Set to 0 (LOW):

ubus call onion gpio '{"command":"set", "params":{"gpio":"7", "value":"0"}}'

Set to 1 (HIGH):

ubus call onion gpio '{"command":"set", "params":{"gpio":"7", "value":"1"}}'

Sample Return:

{
        "success": true,
        "pin": "7",
        "value": "0"
}

Get Direction Command

Get the current direction of the GPIO

Usage:

ubus call onion gpio '{"command":"get-direction", "params":{"gpio":"<gpio number>"}}'

Sample Return:

{
        "success": true,
        "pin": "7",
        "direction": "output"
}

The direction value will be either input or output

Set Direction Command

Set the direction of the GPIO

Usage:

Set to OUTPUT:

ubus call onion gpio '{"command":"set-direction", "params":{"gpio":"7", "value":"output"}}'

Set to INPUT:

ubus call onion gpio '{"command":"set-direction", "params":{"gpio":"7", "value":"input"}}'

Sample Return:

{
        "success": true,
        "pin": "7",
        "direction": "out"
}

Status Command
