If the poll control cluster are used, the default poll intervals can be set in the constructor of an application class.
e.g. ZigBee Switch application : ColorSwitchApplication.cpp
If the poll control cluster is not used, start or change the polling interval using:
void EnablePolling(const CCompactTimerService::ticks_diff_t interval)
Example usage
aps.m_nwk.m_nlme.EnablePolling(CCompactTimerService::ticksPerSecond / 4); // 250ms
