How to Use

package main

        "gobot.io/x/gobot/platforms/parrot/minidrone"
)

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

        work := func() {
                drone.On(minidrone.Battery, func(data interface{}) {
                        fmt.Printf("battery: %d\n", data)
                })

                drone.On(minidrone.FlightStatus, func(data interface{}) {
                        fmt.Printf("flight status: %d\n", data)
                })

                drone.On(minidrone.Takeoff, func(data interface{}) {
                        fmt.Println("taking off...")
                })

                drone.On(minidrone.Hovering, func(data interface{}) {
                        fmt.Println("hovering!")
                        gobot.After(5*time.Second, func() {
                                drone.Land()
                        })
                })

                drone.On(minidrone.Landing, func(data interface{}) {
                        fmt.Println("landing...")
                })

                        fmt.Println("landed.")
                })

                time.Sleep(1000 * time.Millisecond)
                drone.TakeOff()
        }

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

        robot.Start()
}

How to Connect

The Parrot Minidrones are Bluetooth LE devices.

You need to know the BLE ID or name of the Minidrone you want to connect to. The Gobot BLE client adaptor also lets you connect by friendly name, aka "RS_1234".

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/minidrone.go RS_1234

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/minidrone.go
sudo ./minidrone RS_1234

Windows
