*
* Example project demonstrating the CC26xx platforms
*
* This example will work for the following boards:
* - srf06-cc26xx: SmartRF06EB + CC26XX EM
* - sensortag-cc26xx: CC26XX sensortag
*
* By default, the example will build for the srf06-cc26xx board. To switch
* between platforms:
* - make clean
* - make BOARD=sensortag-cc26xx savetarget
*
* or
*
* make BOARD=srf06-cc26xx savetarget
*
* This is an IPv6/RPL-enabled example. Thus, if you have a border router in
* your installation (same RDC layer, same PAN ID and RF channel), you should
* be able to ping6 this demo node.
*
* This example also demonstrates CC26xx BLE operation. The process starts
* the BLE beacon daemon (implemented in the RF driver). The daemon will
* send out a BLE beacon periodically. Use any BLE-enabled application (e.g.
* LightBlue on OS X or the TI BLE Multitool smartphone app) and after a few
* seconds the cc26xx device will be discovered.
*
* - etimer/clock : Every CC26XX_DEMO_LOOP_INTERVAL clock ticks the LED defined
* as CC26XX_DEMO_LEDS_PERIODIC will toggle and the device
* will print out readings from some supported sensors
* - sensors : Some sensortag sensors are read asynchronously (see sensor
* documentation). For those, this example will print out
* readings in a staggered fashion at a random interval
* - Buttons : CC26XX_DEMO_SENSOR_1 button will toggle CC26XX_DEMO_LEDS_BUTTON
* - CC26XX_DEMO_SENSOR_2 turns on LEDS_REBOOT and causes a
* watchdog reboot
* - The remaining buttons will just print something
* - The example also shows how to retrieve the duration of a
* button press (in ticks). The driver will generate a
* sensors_changed event upon button release
* - Reed Relay : Will toggle the sensortag buzzer on/off
