init(instructionClass:instructionCode:p1Parameter:p2Parameter:data:expectedResponseLength:)

Creates an APDU object with the instruction class and code, parameter bytes, and expected response length.

Declaration

init(instructionClass: UInt8, instructionCode: UInt8, p1Parameter: UInt8, p2Parameter: UInt8, data: Data, expectedResponseLength: Int)

instructionClass:
The instruction class (CLA) byte value.
instructionCode:
The instruction code (INS) byte value.
p1Parameter:
The P1 parameter byte value.
p2Parameter:
The P2 parameter byte value.
data:
The data to transmit. The APDU object specifies the length of the transmission data in the Lc field.
expectedResponseLength:
The expected response data length (Le) in bytes. The value should be one of the following:
- A length between 1 and 65536 inclusively.
- –1 when you expect no response data.
- 256 to send 00 as the short Le field value, assuming the data field is less than 256 bytes.
- 65536 to send 0000 as the extended Le field.

A newly initialized ISO 7816 APDU object.

If your app needs more precise control of the APDU format, use init(data:) to create the APDU object.
