send(ins:p1:p2:data:le:)

Declaration

@backDeployed(before: macOS 27.0, iOS 27.0, tvOS 27.0, watchOS 27.0, visionOS 27.0)
final func send(ins: UInt8, p1: UInt8, p2: UInt8, data: Data? = nil, le: Int? = nil) async throws -> (sw: UInt16, response: Data)

Parameters

• ins:

  Instruction byte of the APDU command.

• p1:

  P1 parameter byte.

• p2:

  P2 parameter byte.

• data:

  Optional command data.

• le:

  Optional expected response length.

Return Value

A tuple containing the status word (sw) and response data.

Discussion

In an async context, Swift prefers this overload over the synchronous send(ins:p1:p2:data:le:) throws method. To call the synchronous overload from an async context, use a typed function reference cast: card.send as (UInt8, UInt8, UInt8, Data?, Int?) throws -> (UInt16, Data)
