Debug Properties

PROP 16384: PROP_DEBUG_TEST_ASSERT

• Type: Read-Only
• Packed-Encoding: b

Reading this property will cause an assert on the NCP. This is intended for testing the assert functionality of underlying platform/NCP. Assert should ideally cause the NCP to reset, but if assert is not supported or disabled boolean value of false is returned in response.

PROP 16385: PROP_DEBUG_NCP_LOG_LEVEL

• Type: Read-Write
• Packed-Encoding: C

Provides access to the NCP log level. Currently defined values are (which follows the RFC 5424):

• 0: Emergency (emerg).
• 1: Alert (alert).
• 2: Critical (crit).
• 3: Error (err).
• 4: Warning (warn).
• 5: Notice (notice).
• 6: Information (info).
• 7: Debug (debug).

If the NCP supports dynamic log level control, setting this property changes the log level accordingly. Getting the value returns the current log level. If the dynamic log level control is not supported, setting this property returns a PROP_LAST_STATUS with STATUS_INVALID_COMMAND_FOR_PROP.

PROP 16386: PROP_DEBUG_TEST_WATCHDOG

• Type: Read-Only
• Packed-Encoding: Empty

Reading this property will causes NCP to start while(true) ; loop and thus triggering a watchdog. This is intended for testing the watchdog functionality on the underlying platform/NCP.
