Random delay before advertising

[Zachary16]

Hello Everyone,

I would like to implement a random delay of 10 to 3000ms before my development kit start advertising itself.

I'm using nRF5dk v17.1.0. 

How do i go about this?

Regards,

Zachary

Hi Kazi,

Apologies for the late reply. I need this feature to prevent two devices to advertising at the same time. 

I would like to place the random delay of 0 to 3 seconds at the start so that once the device is powered up, it will there will be a delay buffer before it initial to advertise or other event such as reading adc or scan. 

Regards,

Zachary

Hello Zachary,

You need to set how long the app_timer instance should be delayed until it executes. So a while loop like this will be there- 

while(wait_for_this_variable)

the formula of delayed app inside the nrf_delay_ms () function cna be implemented like this: 

nrf_delay_ms((random_16_bit_number + 10) % 3000)

Try to implement this in your code.
