Thanks.

Sorry about the delayed response.

The reason it fails is probably the disconnect reason. BT_HCI_ERR_CONN_TIMEOUT is not acceptable as a disconnect reason.

Try using BT_HCI_ERR_REMOTE_USER_TERM_CONN instead.

Hey Joakim

Actually, I mean this call

static void connection_thread_fn(void) {
	k_sem_init(&ble.conn_timeout_sema, 0, 1);
	for (;;) {
		if (k_sem_take(&ble.conn_timeout_sema, K_FOREVER) == 0) {
			LOG_DBG("Start to disconnect the device");
			if (ble.current_conn != NULL) {
				bt_conn_disconnect(ble.current_conn, BT_HCI_ERR_CONN_TIMEOUT);
			}
		}
	}
}

Regards,

Thanks.

Looking at your code; Which call to bt_conn_disconnect are you referring to?

Thanks Joakim,

the connection is never terminated after executing the function bt_conn_disconnect

Thanks.

I'll take a look at your code.

[quote user=""]In the code below bt_conn_disconnect function is executed but the connection is still there.[/quote]

Is the connection never terminated or is the problem that the device instantly reconnects to the device after calling bt_conn_disconnect()?

Thank you for your question.

Could you please add which version of the SDK you are working with?
