Hey,

Thanks a lot for pointing out those sample projects. I was able to find the problem. The problem was that I had this code in function scan_filter_match:

	err = bt_conn_le_create(device_info->recv_info->addr, conn_params,
				BT_LE_CONN_PARAM_DEFAULT,
				&default_conn);

And then in connected callback I had this:

default_conn = bt_conn_ref(conn);

Meaning that I was ending up with 2 references after every connection.

So when I was deleting the reference from default_conn there was always one reference left. Thats why it was finding it on reconnection and giving the previously mentioned error.

What sample projects are you using? I would suggest checking out the peripheral_hr_coded and central_hr_coded sample projects. Do you start advertising again after a disconnected event in the peripheral device? You can check if it starts advertising again or not by checking the disconnected() call in main.c.

Best regards,
