# 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
|
|
|
|
Please refer to the main [README.md](https://github.com/hybridgroup/gobot/blob/release/README.md)
|
|
|
|
## How to Use
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"os"
|
|
"time"
|
|
|
|
"gobot.io/x/gobot/v2"
|
|
"gobot.io/x/gobot/v2/platforms/bleclient"
|
|
"gobot.io/x/gobot/v2/drivers/ble/sphero"
|
|
)
|
|
|
|
func main() {
|
|
bleAdaptor := bleclient.NewAdaptor(os.Args[1])
|
|
sprk := sphero.NewSPRKPlusDriver(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,
|
|
)
|
|
|
|
err := robot.Start()
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
}
|
|
}
|
|
```
|
|
|
|
## 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:
|
|
|
|
```sh
|
|
go build examples/sprkplus.go
|
|
sudo ./sprkplus SK-1247
|
|
```
|
|
|
|
### Windows
|
|
|
|
Hopefully coming soon...
