How do I enable/disable automatic advertising after GPIO Pin state?

I want to advertise only when GPIO pin is High. It should not Advertise when GPIO pin is Low.

You can do this by triggering an interrupt on a pin change, and call sd_ble_gap_adv_start() or sd_ble_gap_adv_stop() as appropriate in the interrupt handler.

You could probably make a simple demonstration by basing your code on for example the Beacon Transmitter Sample Application and looking at the Pin Change Interrupt Example.

On sd_ble_gap_adv_stop() device is getting restart. Following steps i am doing

• Advertising
• Connect
• GET Command from nus
• Change state of GPIO-1 which changes GPIO-2 state
• If GPIO-2 is True then sd_ble_gap_adv_start() and If GPIO-2 is False then sd_ble_gap_adv_stop()
