Syntax

int BthCreateSynchronousConnection
(
BT_ADDR         *pbt,
unsigned short  *pHandle,
unsigned int    txBandwidth,
unsigned int    rxBandwidth,
unsigned short  maxLatency,
unsigned short  voiceSetting,
unsigned char   retransmit
);

Parameters

  • pbt
    [in] Pointer to the Bluetooth address.
  • phandle
    [out] Pointer to the connection handle.
  • txBandwidth
    [in] Transmit bandwidth in octets per second.
  • rxBandwidth
    [in] Receive bandwidth in octets per second.
  • maxLatency
    [in] Maximum latency in milliseconds. Must be in the range of 0x0004 through 0xFFFF. 0xFFFF specifies no maximum.
  • voiceSetting
