# Sphero SPRK+
The Sphero SPRK+ is a toy robot from Sphero that is controlled using Bluetooth LE. For more information, go to [http://www.sphero.com/sprk-plus](http://www.sphero.com/sprk-plus)
## How to Install
```
go get -d -u gobot.io/x/gobot/...
```
## 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/sprkplus"
)
func main() {
bleAdaptor := ble.NewClientAdaptor(os.Args[1])
sprk := sprkplus.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))
sprk.SetRGB(r, g, b)
})
}
robot := gobot.NewRobot("sprk",
[]gobot.Connection{bleAdaptor},
[]gobot.Device{sprk},
work,
)
robot.Start()
}
```
## How to Connect
The Sphero SPRK+ is a Bluetooth LE device.
You need to know the BLE ID of the SPRK+ you want to connect to. The Gobot BLE client adaptor also lets you connect by friendly name, aka "SK-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.
If you connect by name, then you do not need to worry about the Bluetooth LE ID. However, if you want to connect by ID, OS X 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.
For example:
GODEBUG=cgocheck=0 go run examples/sprkplus.go SK-1247
### 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/sprkplus.go
sudo ./sprkplus SK-1247
### Windows
Hopefully coming soon...
