From any AntPluginPcc you can call these functions:
getDeviceNumber(); - Returns the ANT Device Number, most likely the one you want
getDeviceName(); - This name is the user's saved name if this device is saved in the user's device database, or a generated name if it isn't.
isUserRecognizedDevice(); - Returns a value indicating if this device has been saved to the user's device database.
isUserPreferredDeviceForPlugin(); - Returns a value indicating if this device is set as the preferred device for this plugin type in the user's device database.
Each instance of a PCC represents an ANT channel which is tracking (or acting as) a particular device (not including device profiles which use multiple ANT channels...).
