Perfect. It solved it. Thank you.

Ok. I thought it was the disconnect itself that was the problem . According to the log the bond procedure is actually being completed on the first connection (this: [00:00:10.922,851] <info> peer_manager_handler: Connection secured: role: Central, conn_handle: 0, procedure: Bonding).

I guess the problem is that notification is not being enabled on the first connection then? The central must wait for the PM_EVT_CONN_SEC_SUCCEEDED event before enabling the notification since you've changed the CCCD write access to "Just works".

I know. But it disconnects 10 seconds after the last BLE event. It seems never to finalize before disconnection and re-connection.

Hi,

The disconnect appears to be caused your "disconnect" timer, see app.c->AppDisconnectHandler().

By the way. I have also posted another issue on this project. Can also be visualized with this project.

https://devzone.nordicsemi.com/f/nordic-q-a/40751/various-notification-delays

And I forgot to write that connection is established when pressing the button 3 and 4, and the two buttons are mapped to LED 3 and 4 on the central. when holding the buttons the state is notified every 200 ms. When Idle for some time the connection is terminated.

Hi Vidar

Sorry for the delay, I have been off project for a while.

I have uploaded the two projects, both peripheral and central to my FTP server. You can download via following link: http://leonhardt.dk/footpedal.zip. You can find the Keil project files in the folders "foot pedal controller" and "foot pedal receiver".

Happy new year :-)

Kasper

Hi,

Yes there's something wrong, you should be able to perform bonding without losing the link. Could you upload the project so I can try to debug it here? I have not seen that disconnect reason before (0x15 == BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION). All examples that include the Peer manager support bonding.

EDIT: 0x15 corresponds to BLE_HCI_REMOTE_DEV_TERMINATION_DUE_TO_POWER_OFF, and not BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION which is a common status code.

Forgot to write that I have a system with two PCA10040 boards both running with SD version s132_nrf52_6.1.0. The application is build with SDK version 15.2.
