Assembly:
SdkApi.Core (in SdkApi.Core.dll) Version: 2.15.2634
Syntax public byte[] SendAndWaitForValidResponse(
byte[] dataToSend,
int initialResponseTimeout,
int responseCompletionTimeout,
ResponseValidator validator
)
Public Function SendAndWaitForValidResponse (
dataToSend As Byte(),
initialResponseTimeout As Integer,
responseCompletionTimeout As Integer,
validator As ResponseValidator
) As Byte()
public:
virtual array<unsigned char>^ SendAndWaitForValidResponse(
array<unsigned char>^ dataToSend,
int initialResponseTimeout,
int responseCompletionTimeout,
ResponseValidator^ validator
) sealed
Parameters
- dataToSend
- Type: SystemByte
Byte array of data to send - initialResponseTimeout
- Type: SystemInt32
The maximum time, in milliseconds, to wait for the initial response to be received.
If no data is received during this time, the function returns a zero length array. - responseCompletionTimeout
- Type: SystemInt32
After the initial response, if no data is received for this period of time, the
input is considered complete and the method returns. - validator
- Type: Zebra.Sdk.CommResponseValidator
If the response satisfies this validator, the input is considered complete and the method returns.
May be used to avoid waiting for more data when the response follows a known format.

Implements
ConnectionSendAndWaitForValidResponse(Byte, Int32, Int32, ResponseValidator)Exceptions Remarks
The software returns immediately if the data received satisfies validator. The connection must be open before this method is called.
If sendAndWaitForResponse is called when a connection is closed, a ConnectionException is thrown.
