+
+The demo runs on an WvShare BLE400 board. This board is powered by a Nordic
+Semiconductor nRF51822 processor which is an ARM Cortex-M0 with bluetooth radio
+hardware. This board can be easily found on chinese websites.
+
+** The Demo **
+
+This demo will print the standard TestThread output and blink all LEDs in a

+
+** Build Procedure **
+
+The demo has been tested using the freely available GCC ARM Embedded toolchain.
