BLE Central role: Unable to scan for directed advertisement.

[Prem]

My set Up: TI as Peripheral, Android as Central, Nordic as Central

I am doing directed advertisement using TI as peripheral.

Using Andriod as central, I am successfully able to scan for the peripheral doing directed advertisement, and also able to initiate a connection to the peripheral.

I am trying to achieve the same using Nordic as central. But, I am not able to scan for directed advertisement. I have also tried 'whitelisting' the peripheral for scanning, still scanning for directed advertisement was not possible. Is there any specific scanning parameter I need to set? OR is this a limitation on Nordic side?(sdk version:8.0.0))

PS: The Nordic device could successfully scan for the TI peripheral if using undirected advertisement, but fails to scan the peripheral doing directed advertisement.

is the TI peripheral doing a directed advertisement for Nordic central? else as soon as it sees that it is directed adv packet and not for it, it will just ignore it and not send any events to LinkLayer.

Yes, TI peripheral is doing directed advertisement for Nordic central.

[Susheel Nuguru]

That should work, can you please sniff the packets and send us a log.

[Susheel Nuguru]

I have checked your log and the timestamp from the advertiser (TI) looks ok. So the only thing left to check is if the initiator address correct. Nothing much can go wrong in direct advertising. There is nothing more that can be concluded from that logs.

[Susheel Nuguru]

can you send me logs where TI chip does undirected advertising and then gets connected to Nordic chip and then change it to directed. Make sure the switch from undirected to directed is recorded by the sniffer.
