Hello there


I am using  MCUXpresso IDE v10.3.1 [Build 2233] [2019-02-20] and SDK v2.2.0.

I am testing the qn908xcdk_wireless_examples_bluetooth_power_profiling_freertos example code.

After pressing the button 1 four times controller goes into the deep sleep mode 3 sand start advertising. By default the example is having the adverting interval between 1 to 2.5 sec. 

I am able to change that interval by using the macro = time interval (in ms) / 0.625 ms, where the macro is assigned into gReducedPowerMinAdvInterval_c and gReducedPowerMaxAdvInterval_c intervals. 

I am able to successfully set the interval of 10 to 20 seconds. by setting the macros to 16000 and 32000, and it works.

But when I need to set advertising interval to 20 to 30 seconds, I do not see any adverting form the controller on mobile app.


Can anyone help me to resolve this issue
