Hi 

     I am using nRF5_SDK_17.0.2_d674dde  with softdevice S140  have sample example as   ble_app_cts_c but when i run the code first central disconnected but when i going to pair then it give following error as 

peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 4352 and it gets disconnected after couple of sec.

Can  you guide me how to solve above  problem.

Hi,

The error code corresponds to 'PM_CONN_SEC_ERROR_DISCONNECT', and it indicates that the connection was terminated during the pairing procedure. Are you able to debug the app to see why it disconnects? Maybe it's because it does not find the required service on the connected GATT Server?

    when i debugg on NRFconnect on my mobile  then following error occur as:

 Error22 (0x16):GATT CONN TERMINATE LOCAL HOST

Please check if the device may be paired already by going to the Bluetooth settings on your phone. Remove the device if it is. Also, are you able to stay connected when you try other examples such as ble_app_hrs?
