The 

 features an on-chip supply voltage sensor, an internal input channel for the ADC (see ADC).

The 02-battery sample application creates a task which periodically reads the value of the DN_BATT_DEV_ID device and prints the raw returned value on the CLI, as shown in the CLI capture below:

The raw reading is expressed in tenths of mV.

The 01-join sample application uses the Helper Modules to initialize the CLI Module and interaction with the local interface. In particular, it configures the loc_task helper module to join the network and open a socket bound to UDP port 60000.

It uses a single task (sendTask) which:

• waits for the loc_task helper module to have joined the network (by pending on the joinedSem semaphore);

• every 10s, send a UDP packet to the IPv6 address of the manager.
