fail to set 51822 broadcast interval

[yiran]

Hi,

I want to change the interval time of 51822 dongle with the instruction here devzone.nordicsemi.com/.../

The default value is 100ms as following

#define NON_CONNECTABLE_ADV_INTERVAL    MSEC_TO_UNITS(100, UNIT_0_625_MS)

When I set the interval more than 100ms, it works properly. However, when I set the interval to any time less than 100ms, the beacon doesn't work anymore. Can anyone help me?
