Hai, how you doing?
I am facing difficulty in trying to connect ble devices with windows 10. I am using BLE dongle APLIC WDP 304747 (Also tried another couple of BLE dongles).
I am using nrf52840 DK and Softdevice s140_nrf52_7.2.0. SDK version is 17.0.2
Initially a connection is successfully established between the windows and ble application. Then a disconnect event happens with a return code of 0x13.

I noticed the issue with our custom application. Android and iOS doesnot have this issue.
I then tried to flash the peripheral examples to the DK and obsereved the same behaviour.
You can reproduce this at your end by flashing nordic blinky peripheral example on to nrf5 device (SDK 17 0 2 and s140_nrf52_7.2.0.).
What could be the reason for this. I went through the forum and tried checking various pairing and bonding documentation. But if all the examples in the SDK has the same issue, then I think its better to report before digging deeper in it. Can you please try to reproduce it from your end and help me solve this issue?
Best regards,
