To build for the Blueboard, compile with the flag PLATFORM=BLUEBOARD.
On the LPC17xx, UART1 is used for OpenXC output at the 230000 baud rate. Like on the chipKIT, hardware flow control (RTS/CTS) is enabled, so CTS must be pulled low by the receiving device before data will be sent.
UART data is sent only if pin 0.18 is pulled high. If you are using a Bluetooth module like the BlueSMiRF from SparkFun, you need to hard-wire 5v into pin 0.18 to actually enabling UART. Other hardware implementations (like the Ford prototype) may be able to hook the Bluetooth connection status to this pin instead, to make the status of UART more dynamic.
On the Blueboard LPC1768H, logging will be on UART0 at 115200 baud:
LEDs are not currently supported on the Blueboard.
