    Hey Ben,

    The function HAL_SYSTEM_RESET() can be used a soft reset for the device.

    Hey Ben,

    I don't understand what you are describing. Are you unable to do perform a soft reset of the CC2541? Can you possibly provide a diagram of your system and what you are wanting to accomplish?

    Hello Matt

    Sorry for describe ,My device design plug battery will auto enter advertising mode not via side key when boot up device.

    you can see as uint8 initial_advertising_enable = "TRUE";

    But , If I change this state able to do HAL_SYSTEM_RESET(),when boot up device  will keep advertising mode.I want close advertising. for those step.

    1,bootup device advertising

    2.test function will call HAL_SYSTEM_RESET()

    3.when reset will close advertising or shutdown device

    How can I do? Do you have "shutdown function"?

    Thanks

    If your firmware enables advertising upon start up then no matter how you reset advertising will always be enabled. If you want to selectively enable advertising on start up, which is what I think you are referring to, then you will need to include some type of input that you can use to determine whether or not you should enable advertising. This might be a GPIO input or some type of state variable stored in non-volatile memory for example.

    That way on start up you can read that variable and determine whether or not you should advertise after any given reset.

    Dear Matt

    Thanks your recommends.

    I use this methods you can refer, it can also turn off any state after reset. need send each event and add as below status function. 

    gapProfileState != GAPROLE_CONNECTED

    ---------------------------------------------------------------------------------------------------------------------------------------------------

           uint8 adv_enabled = FALSE;

            // Disconnect

            GAPRole_TerminateConnection();

            // Start advertising

            GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &adv_enabled );

    Thanks a lot
