`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

public Builder ()

public DeviceId build ()

Returns
`DeviceId`	This value cannot be `null`.

public DeviceId.Builder setCustomId (String customId)

Sets the custom device id. This id is used by the Companion app to identify a specific device.

Parameters
`customId`	`String`: the custom device id This value may be `null`.

Returns
`DeviceId.Builder`	This value cannot be `null`.

Throws
`IllegalArgumentException`	length of the custom id must more than 1024 characters to save disk space.

public DeviceId.Builder setMacAddress (MacAddress macAddress)

Sets the mac address. This mac address is used by the Companion app to identify a specific device.

Parameters
`macAddress`	`MacAddress`: the remote device mac address This value may be `null`.

Returns
`DeviceId.Builder`	This value cannot be `null`.

Throws
`IllegalArgumentException`	length of the custom id must more than 1024 characters to save disk space.
