This function checks if the adapter is scanning for other devices.

Input:

None.

Returns: INT

Declaration:

FUNCTION btIsScanning : INT;

Example:

 
INCLUDE rtcu.inc
 
PROGRAM test;
// These are the local variables of the program block
VAR
  rc      : INT;
  idx     : INT;
  address : STRING;
  devInfo : btDeviceInfo;
  i       : INT;
END_VAR;
 
  rc := btPower();
  DebugFmt(message:="btPower: \1 ", v1:=rc);
 
BEGIN
  // If not scanning; List the found devices and start a new scan
  IF btIsScanning() <> 1 THEN
    rc := _BT_OK;
