The OCSDK stack provides APIs for testing the radio - typically used for top-level assembly testing, and radio certification testing.  

The 03-radioTest Sample Application

The application provides 3 CLI functions (available by typing help) for radio testing:

• initPer - sets the initial period, in ns.  By default, it is set to DN_PWM_8P9MS (8.9 ms). Cannot be called when the PWM is open.
• initDuty - sets the initial duty cycle, expressed as the asserted portion of the period in ns.  
• openPWM - opens the DN_PWM_DEV_ID device (PWM0,  LTC5800 pin 49). The device must be opened before enabling/disabling the PWM. 
• enablePWM - enables the PWM signal output on PWM0.
• disablePWM - disables the PWM signal output on PWM0
• setDuty - sets the current duty cycle, expressed as the asserted portion of the period in ns. 
• closePWM - closes the pwm device and disable output. The PWM must be closed before changing the period.

It also provides a reset command for easily resetting the part.

Each CLI command prints a confirmation:

Implementation Details

The 03-radioTest sample application uses the Helper Modules to initialize the CLI Module and for interaction with the local interface. It passes JOIN_NO in the fJoin flag when initializing the local module in the loc_task_init() to prevent the local module from attempting to join, as the radio can only be tested when the mote is in either the idle or radioTest state.
