BthWriteLinkPolicySettings

  • Article

This function writes the current link policy for the existing connection with the peer specified by its Bluetooth address.

Note   To preserve Win32 compatibility, consider using the Winsock equivalent of this function. To do so, pass SO_BTH_SET_LINK_POLICY as the optname value in setsockopt.

int BthWriteLinkPolicySettings(
  BT_ADDR* pba,
  unsigned short lps
);

Parameters

  • pba
    [in] Pointer to the Bluetooth address.
  • lps
    [in] The link policy for the existing connection. The following table shows the flags that can be used in combination.
    Flag Description
    0x0000 Disables all LAN Manager (LM) modes.
    0x0001 Enables the master slave switch.
    0x0002 Enables Hold mode.
    0x0004 Enables Sniff Mode.

Return Values

This function returns ERROR_SUCCESS when it completes successfully.

A return value of ERROR_SERVICE_NOT_ACTIVE indicates that the hardware is not inserted or that the Bluetooth stack is not present.

A return value of ERROR_NOT_FOUND indicates that an active ACL connection to the peer that is specified by the Bluetooth address does not exist.

Other standard error codes may be returned as appropriate.
