Field Detail

LCP

public static final int LCP

Lego Communications Protocol (LCP) I/O mode. The LCP is defined by The Lego Company to allow limited remote command control of a NXT brick. See the Lego Mindstorms Site. Look for the Bluetooth Developer Kit in Support | Files | Advanced

RAW

public static final int RAW

RAW I/O mode. This mode is just that and omits any headers. It is used normally for connections to non-NXT devices such as cell phones, etc.
