Class ConfigPage

java.lang.Object
  com.sun.spot.peripheral.ConfigPage

public class ConfigPage
extends Object

Each Spot reserves some flash memory for configuration information. The ConfigPage class converts that information to and fro between a raw byte array and structured Java data.
The information is not held in normal Java streamed representations because the information must also be accessible from the C language bootstrap.

To obtain the current config page use:

Spot.getInstance().getConfigPage()
