Blink a led with Beacon advertising

Hi,

I am advertising I-Beacons using STM32WB. I need blink a led during the whole time of advertising. I have initialized below functions,

I-Beacon Process()

I-Beacon Initialization()

but I am unable blink the led at this moment. (I was able to advertise the beacon).

Can anyone solve the problem and give me the exact point where I have to include the codes for blink led?
