TestLogStorage is a threaded implementation of an application that takes a dummy
sensor readings of a counter, logs it flash, and then sends it out over the
-radio at some later time. In the current implementation, each sensor reading is
+serial port at some later time. In the current implementation, each sensor reading is
taken once every 3000ms, and records containing a set of readings from each
iteration are batched out over the radio every 10000ms. This application is
very similar to the SenseStoreAndForward application contained in this same
To run this application install it on a mote via the command:
make <platform> cthreads install
-Valid platforms are currently: tmote, telosb, iris, mica2, and micaz

Readings are taken from the dummy sensor and logged to flash as one record in an
infinite loop. Records are then read out of flash and and sent out over the
-radio interface in separate infinite loop. Before the application starts

running, the entire contents of the flash drive are erased.
A successful test will result in LED0 remaining solid for approximately 6s while
the flash is being erased. After that LED0 will toggle with each successful

toggling in rapid succession once every 10000ms as records are successfully read

-Additionally, the TestLogStorage mote writes its records out to the serial

+Since the TestLogStorage mote writes its records out to the serial
+port, you can test that the application is working properly by reading these
packets (e.g., through seriallisten) and checking that they have reasonable
values, counting up from 0. E.g.:
