RF ISO 15693 High-level RESET TO READY command

To issue an RF ISO 15693 High-level RESET TO READY command, send the

FEISC_0xB0_ISOCmd

function with the strReqData set to ‘0026’ (RESET TO READY

request).

Below is an example of code in Visual Basic and C/C++.

5.3.1

RESET TO READY command

Visual Basic source code example

Private Function cmd_ResetToReadyRF_FEIG() As Boolean

Dim strReqData As String

Dim lngReqDataLen As Long

Dim lngRspLength As Long

Dim strRespData As String * 512

Dim lngRespDataLen As Long

Dim lngStatus As Long

' Reset to Ready request Host mode : 0x2600

strReqData = "2600"

lngReqDataLen = Len(strReqData)

' FEIG USB INVENTORY request in Host Mode

lngStatus = FEISC_0xB0_ISOCmd(lngAttachedDeviceHandle(0), &HFF, _

strReqData, lngReqDataLen, _

strRespData, lngRespDataLen, _

' RF INVENTORY REQUEST RESULT

' if(lngStatus = 0) then PASS else FAIL

' if (lngRespDataLen = 0) then No transponder answer

' else strRespData contains the transponder(s) answer(s)

If (lngRespDataLen = 0) Then

cmd_ResetToReadyRF_FEIG = False

Else

cmd_ResetToReadyRF_FEIG = True

End If

End Function
