Class definition

public class Device

The Device class is an abstraction for NeuroMD BLE devices. This abstraction provides functions for changing of device state by executing commands and setting parameters. Each device have different sets of supported commands and parameters, Device class has functions designed to get information about these sets. Callibri and Braibit devices has different parameters sets and provides different ways to access them. Device class hides all differences behind its interface and provides universal way to read and write parameters, execute commands and receive biopotential signals.

Fields Summary

Modifier and Type	Field and Description
SubscribersNotifier<ParameterName>	parameterChanged Subscribe this event to receive notifications about changes of device parameters

Constructor Summary

You are not able to create Device directly. Use DeviceScanner to find and create devices

Methods Summary

Modifier and Type	Method and Description
void	connect() Establishes connection with device services
void	disconnect() Disconnects from device
ChannelInfo[]	channels() Returns information about supported channels. Check this information before creation of channel. If device does not support channel, channel object won't be initialized.
int	getBatteryLevel() Returns battery charge level in percents
NeuroDeviceError	getError() Returns device error state information
DeviceFeature[]	getFeature() Returns supported device features
java.lang.String	getName() Returns name of BLE device
NeuroDevice	getNeuroDevice() Returns this object
SignalSubsystem	getSignalSubsystem() Returns subsystem for SIGNAL device feature
NeuroDeviceState	getState() Returns common device state
StimulationSubsystem	getStimulationSubsystem() Returns subsystem for STIMUL device feature
