# Sphero Ollie

The Sphero Ollie is a toy robot from Sphero that is controlled using Bluetooth LE. For more information, go to [http://www.sphero.com/ollie](http://www.sphero.com/ollie)

## How to Install
```
go get -d -u gobot.io/x/gobot/... && go install gobot.io/x/gobot/platforms/ble
```

## How to Use
```go
package main

import (
	"os"
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/platforms/ble"
	"gobot.io/x/gobot/platforms/sphero/ollie"
)

func main() {
	bleAdaptor := ble.NewClientAdaptor(os.Args[1])
	ollie := ollie.NewDriver(bleAdaptor)

	work := func() {
		gobot.Every(1*time.Second, func() {
			r := uint8(gobot.Rand(255))
			g := uint8(gobot.Rand(255))
			b := uint8(gobot.Rand(255))
			ollie.SetRGB(r, g, b)
		})
	}

	robot := gobot.NewRobot("ollieBot",
		[]gobot.Connection{bleAdaptor},
		[]gobot.Device{ollie},
		work,
	)

	robot.Start()
}
```

## How to Connect

The Sphero Ollie is a Bluetooth LE device.

You need to know the BLE ID of the Ollie you want to connect to. The Gobot BLE client adaptor also lets you connect by friendly name, aka "2B-1247".

### OSX

To run any of the Gobot BLE code you must use the `GODEBUG=cgocheck=0` flag in order to get around some of the issues in the CGo-based implementation.

For example:

    GODEBUG=cgocheck=0 go run examples/ollie.go 2B-1247

OSX uses its own Bluetooth ID system which is different from the IDs used on Linux. The code calls thru the XPC interfaces provided by OSX, so as a result does not need to run under sudo.

### Ubuntu

On Linux the BLE code will need to run as a root user account. The easiest way to accomplish this is probably to use `go build` to build your program, and then to run the requesting executable using `sudo`.

For example:

    go build examples/ollie.go
    sudo ./minidrone 2B-1247

### Windows

Hopefully coming soon...
