41 * port number as per specification.
42 * EDR will not start any specific servers.
43 * LE will not start any specific servers.
44 * @return CA_STATUS_OK or CA_STATUS_FAILED

50 * @brief Starting listening server for receiving multicast search requests
51 * Transport Specific Behavior:
52 * WIFI/ETH Starts multicast server on all available IPs and defined
53 * port number and as per specification.
54 * EDR Starts RFCOMM Server with prefixed UUID as per specification.

63 * Transport Specific Behavior:
