Unable to Receive Directed Advertisements

[karl]

For some reason I'm not able to receive directed advertisements on the nRF51 development kit. I verified my nRF51 peripheral is sending the direct advertisement packets using the Sniffer tool, but the I don't see any BLE_GAP_EVT_ADV_REPORTS being generated on the central while its scanning.

The central does however see the advertisements if I configure them on the peripheral as connectable undirected.

I'm using SDK 10.0.0 for the peripheral and Windows BLE Driver 0.5.0 for the Central.

Thanks

I wanted to add that I am experiencing the exact same issue, and provide more detail on my scenario.

Using:

• nRF51822 on both sides
• SDK 10.0
• SD1.10 8.0.0 on peripheral side
• SD1.20 2.1.0 on central side
• both central and peripheral use consistent type 1 (random, static) addresses obtained with sd_ble_gap_address_get()

Code was based on SDK10 examples for heart rate monitor. As long as peripheral uses non-directed advertising, central quickly sees its advertisements and can connect to it. If directed (fast or slow) advertising is used, the advertisements are never seen (i.e. no BLE_GAP_EVT_ADV_REPORT received).

I've confirmed using Master Control Panel 3.10 that the peripheral is seen sending directed or non-directed advertisements fine.

Let me know if you have any other ideas, or if there's anything else I can provide. Thanks.
