 In BTstack teh functions l2cap_can_send_packet_now(..) and rfcomm_can_send_packet(..) must be called before sending the next L2CAP or RFCOMM packet. Before v1.0, we suggested to check with l2cap_can_send_packet_now(..) or rfcomm_can_send_packet(..) whenever an HCI event was received. This has been cleaned up and streamlined in v1.0.
