    Greetings Divyani,
    Thank you for your question. Let's start with some systematic checks to see exactly where your issue is coming from. In order to do so, I would need the following information from you:

    - How are you checking for directed advertising being transmitted from the device? Are you checking using a sniffer, a phone, or a different device?

    - Can you enable the RF Observables as described in the debugging section of the BLE5Stack User's guide and see if the PA (visualizes Tx activity) shows any toggles?

    I am verified on power analyzer. Start and stop the advertisement.

    If possible can you guide me how to do directed advertisement and white list.

    Greetings Divyani,

    The Power Analyzer is a good tool to see activity, but it won't show you the whole picture, unfortunately. Do you happen to have access to a Bluetooth Sniffer? This will help you confirm that whatever your device is advertising is according to your configuration. In order to enable directed advertising, you are following the correct steps by using SysConfig, so you're good on that front. What we need to look into now is why your central device is not receiving this.

    What is the scanning device in this case? Is it a phone, another CC26X2 launchpad, or another BLE device? This will help me understand how you are testing, and what you want to implement.

    1) Yes, I verified with sniffer tool and also when in white list i mentioned the launchpad address it is showing the advertisement but in mobile it is not showing advertisement.

    2) In directed advertisement (Connectable directed), It is stop advertising where in advertisement data i mention the target address. even my other functionality is also not working if i am selecting directed advertisement.

    If do you have any process notes available for directed advertisement kindly provide us

    Greetings Divyani,

    Thank you for the additional details. This confirms one of my doubts. If you are able to see the directed advertisement on a launchpad, and using a sniffer, transmitting the correct address, then the problem seems to be on the phone side. For instance, I know that iOS does not support directed advertisement. You may have to check for the relevant, and phone manufacturer you are using to double check for your setup.

    I would like to ask about what functionality are you trying to implement by using directed advertisement, so I can understand your application better and suggest solutions accordingly.

    Best,
