directed advertisement

Aiswarya

hello,

I am trying to direct advertisement on NRF51822 board.When giving the peer address i am confused that how to specify the address type of the device, whether BLE_GAP_ADDR_TYPE_PUBLIC or BLE_GAP_ADDR_TYPE_RANDOM_STATIC. How to give this type.

Is it possible to send manufacturer specific data in direct advertisement,or is it possible to send a scan response for a direct advertisement

In my application there are many BLE devices which forms a network.I want to send an advertisement to a specif device with some manufacture specific data ,so that others in neighborhood do not want to respond to the advertisement received with connection requests.

    Please see this for an explaination of the different address types, I think you should use BLE_GAP_ADDR_TYPE_RANDOM_STATIC.

    The directed advertising packets only include the peripherals address and the centrals address, please see Bluetooth Core Specification 4.1, Volume 6, Part B, Section 2.3.1.2.

    Directed advertising with high duty cycle only lasts for 1.28 seconds, and is normally used to do fast reconnections. For slower reconnections, you can use directed advertsing with low duty cycle. Some more detail on directed advertising can be found in this post.
