Unable to reconnect on windows if BLE privacy turned on

[wty]

Hi,

I'm having trouble connecting my peripheral on windows. The pairing works, but once I disconnect, I can no longer connect to it. Windows reports "device unreachable" and pairing again doesn't work. The only way to get out it is clearing the bonding info in MCU.

And if I don't turn on the privacy options, I can connect again without problem.

Here's my configuration on the privacy options.

privacy_params.privacy_mode = BLE_GAP_PRIVACY_MODE_NETWORK_PRIVACY;
privacy_params.private_addr_type = BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE;
privacy_params.private_addr_cycle_s = BLE_GAP_DEFAULT_PRIVATE_ADDR_CYCLE_INTERVAL_S;
privacy_params.p_device_irk = NULL;

err_code = pm_privacy_set(&privacy_params);
APP_ERROR_CHECK(err_code);

What's the problem? I'm using the latest windows 10, so it should support the privacy options.

Can you check out this thread:
https://devzone.nordicsemi.com/f/nordic-q-a/39921/how-to-set-my-nrf-device-to-use-the-private-resolvable-address 

You can find example code using both pm_privacy_set() and sd_ble_gap_privacy_set(). You may try to use BLE_GAP_PRIVACY_MODE_DEVICE_PRIVACY first, since the examples use that.

While debugging you may consider allowing repairing:
