SDK - 15.2.0
IDE - Segger Embedded Studio
Computer platform Windows 10
I added to example "ble_app_blinky" all the peer manger, because I want to add password in connection.
I was succeeded to do it, but the problem is when I want to connect the phone again.
In the first time the phone ask me to write the pin code. If I close the bluetooth, open it again and try to connect to the module, I cant until I undo matching.
Can someone tell me what to do please?
I used to have the same problem. There are 2 possible reasons:
1/ There is a problem with the phone Bluetooth, usually happens with Android phones.
2/ Have you implemented this correctly?
I think you should upload your program here for a better support.

This are the code. I dont think the phone is the problem, And I think the second solution is implemented in the code
Hi
In projects where the peer manager is missing we handle some of the security related callbacks in the ble_evt_handler. Try removing/commenting out BLE_GAP_EVT_SEC_PARAMS_REQUEST and BLE_GATTS_EVT_SYS_ATTR_MISSING to avoid any conflicts with the peer manager.
Best regards,
Simon
