Reconnect using directed advertisement cc2541

Hi all,

Can anyone please suggest how can i use directed advertisement? In my application i need to do analog processing during which connection gets disconnected. What i want is to establish re-connection in as less time as it can. I have read about directed advertisement which takes much lesser time to connect to the central. For the first time i will be using undirected advertisement and when device connects with peripheral, i will store the MAC address of central and later will use directed advertisement for faster re-connection after i have done my analog processing.

So can anyone please tell

1)how can i implement this? Which function do i need to call for this?

2)Is there any way to know peripheral has successfully connected to the central?

Thanks

    Hi,

    I don't have any idea for your first query. But for second, you will get a peripheralStateNotificationCallback when the state of the peripheral device changes. And when peripheral device connects to the central device the state will change from GAPROLE_ADVERTISING to GAPROLE_CONNECTED. Using this you can detect that the peripheral device is successfully connected to the central device.

    Hope this helps!

    Thanks,

    Dhaval
