Directed Advertising Peripheral

[Luke Richards]

Hi

I have a Nordic nRF51 as a Peripheral. I have it open advertising until it connects for the first time to an Android handset.

When a connection is made it stays in directed mode advertising so that no other devices can connect in the future (for security purposes)

On a power cycle of the Android handset, it changes its address so I can never connect to the peripheral again, since its directing at the old handset address.

Any help would be much appreciated

Regards Luke

Hello Hung Bui,

I hope you are still part of the network. I noticed that you were discussing this topic couple of years ago which is somehow related to my issue.

I am using nrf5340 Audio DK, and I would like to implement this Whitelist on the peripheral (headset) device to only connect to a specific central (gateway). I actually have 2 centrals so using the whitelisting, I would like to shift the connection between them when the user presses a button for example, so I thought that whitelisting can help the headset to connect with the device specified. Would you mind to guide mw on how I can do that or maybe show me an example I can refer to?

Thanks!

Hi Loal, 
I'm not an expert with the Audio SDK so I can't really give you the exact answer. I would suggest to create a new case. 
If the Audio stack use the same mechanism as normal BLE then it shouldn't be a problem change the whitelist or change the directed advertising to point to a single central and switch between when them.
