This section refers to the following sample application(s):

  • 02-random


The 

LTC5800

 features a random number generator device which samples the thermal noise of an internal circuit to generate a sequence of random bytes.

You can not use this device after having issued the join or search commands to the mote. Doing so will result in the API returning the DN_ERR_STATE error code. This device can not be used if the mote is configured to join automatically.

The 02-random Sample Application

The 02-random sample application creates a task which periodically reads 16 bytes from the random number generator device. It prints those bytes on the CLI, in hexadecimal format, as shown below:
