Class Garmin.DeviceControl

Garmin.DeviceControl The controller must be unlocked before anything can be done with it. Then you'll have to find a device before you can start to read data from and write data to the device.

We use the observer pattern to handle the asynchronous nature of device communication. You must register your class as a listener to this Object and then implement methods that will get called on certain events.

Events:

onStartFindDevices called when starting to search for devices. the object returned is {controller: this}

onCancelFindDevices is called when the controller is told to cancel finding devices {controller: this}

onFinishFindDevices called when the devices are found. the object returned is {controller: this}

onException is called when an exception occurs in a method object passed back is {msg: exception}

onInteractionWithNoDevice is called when the device is lazy loaded, but finds no devices, yet still attempts a read/write action {controller: this}

onStartReadFromDevice is called when the controller is about to start reading from the device {controller: this}

onFinishReadFromDevice is called when the controller is done reading the device. the read is either a success or failure, which is communicated via json. object passed back contains {success:this.garminPlugin.GpsTransferSucceeded, controller: this}

onWaitingReadFromDevice is called when the controller is waiting for input from the user about the device. object passed back contains: {message: this.garminPlugin.MessageBoxXml, controller: this}

onProgressReadFromDevice is called when the controller is still reading information from the device. in this case the message is a percent complete/ {progress: this.getDeviceStatus(), controller: this}

onCancelReadFromDevice is called when the controller is told to cancel reading from the device {controller: this}

onFinishWriteToDevice is called when the controller is done writing to the device. the write is either a success or failure, which is communicated via json. object passed back contains {success:this.garminPlugin.GpsTransferSucceeded, controller: this}

onWaitingWriteToDevice is called when the controller is waiting for input from the user about the device. object passed back contains: {message: this.garminPlugin.MessageBoxXml, controller: this}

onProgressWriteToDevice is called when the controller is still writing information to the device. in this case the message is a percent complete/ {progress: this.getDeviceStatus(), controller: this}

onCancelWriteToDevice is called when the controller is told to cancel writing to the device {controller: this}

Defined in: GarminDeviceControl.js.
