restart after ble_advertising_on_ble_evt(p_ble_evt)

[Matt]

On an ble advertising timeout an event is dispatched to : ble_advertising_on_ble_evt(p_ble_evt)

I notice the application restart and suspect it due to : ble_advertising.c

"ble_advertising.c" 
   static ble_adv_mode_t adv_mode_next_get(ble_adv_mode_t adv_mode)
    {
        return (ble_adv_mode_t)((adv_mode + 1) % BLE_ADV_MODES);
    }

That return an invalid adv mode code

In the current application the unit should not restart on advertising timeout. Is there a way of accomplishing this ?

Wouldn't it then return 4 = BLE_ADV_MODE_SLOW? Seems valid to me. Maybe ble_advertising_start() is returning an error? If it is, what is it? You can use the debugger with breakpoint to check it. Remember to turn off optimizations.

Yes, if the return statement succeed the next advertising mode is set to 4 BLE_ADV_MODE_SLOW. The statement does not execute. The below code the SEGGER_RTT does not print out and restart...

  static ble_adv_mode_t adv_mode_next_get(ble_adv_mode_t adv_mode)
{
	SEGGER_RTT_printf(0,"Adv mode: %d\n",adv_mode);
	return (ble_adv_mode_t)((adv_mode + 1)%BLE_ADV_MODES);
} 

Removed the -O optimization flag from Makefile.
