Xcode read Bean serial

[Zerethor]

Hi,

I am trying the OSX SDK, just making a simple interface to connect multiple beans to a mac and reading strings from the serial.

I can't find a function to read the serial in the SDK, am I missing something?
Thanks

You need to implement the serialDataReceived() method for your PTDBeanDelegate class.

I was trying to find a link to the documentation page for this, but some links on the Bean's website are down right now.

Hi!

Here is the reference:

This is the class you want to look at:

Best,

Here is an example of my implementation in Swift:

func bean(bean: PTDBean!, serialDataReceived data: NSData!) {

    if (data != nil)
    {
        var strReceived: String = ""

        // Convert the data to a byte array for processing
        let nLength: Int = data.length / sizeof(UInt8)
        var arrData: [UInt8] = [UInt8](count: nLength, repeatedValue: 0)
        data.getBytes( &arrData, length: nLength)

        for (var n: Int = 0; n < nLength; n++)
        {
            if (arrData[n] == CONTROL_ESCAPE_CHAR)
            {
                let nCmdCount: UInt8 = arrData[++n]
                for (var i: Int = 0; i < Int(nCmdCount); i++)
                {
                    self.processControlInput( Int(arrData[++n]), value: arrData[++n] )
                }
            }
            else
            {
                let str = String( UnicodeScalar(arrData[n]) )
                strReceived += str
            }
        }

        self.strContentToAddToConsole += strReceived

        self.updateConsole()
    }
}

The examples explaining the use of serialDataReceived that I've seen are just code snippets.

Since I'm not clear on implementing delegation in Swift, I need to see a complete example of
serialDataReceived in Swift.

Is that possible?

Hi,

Check out

I used serial data to change the onboard RGB LED on the Bean.

Are there any examples of the serialDataReceived() in context anywhere? I created a function as follows, but it appears to never be called.

class Bean: NSObject, PTDBeanManagerDelegate, PTDBeanDelegate {
  // ... other code ...
  func serialDataReceived (bean: PTDBean!, serialDataReceived:NSData) {
    var receivedMessage = NSString(data: serialDataReceived, encoding: NSUTF8StringEncoding)
    print("From serial: \(receivedMessage)")
  }
)

[sarahghp]

Answered my own question. I had a delegate for the BeanManager but not one for the Bean.

This is really helpful, though, I'm setting up my function similarly, and when it comes time for me to call it, I'm not sure whether I should be using 'self.connectedBean?.serialDataReceived()' or another method. when using self.connectedBena?.serialDataReceived()' I get the error "Value of type 'PTDBean' has no member 'serialDataReceived'"

Function:
func bean(bean: PTDBean!, serialDataReceived data:NSData) {
let strReceived: NSData = data
someData.append("'Temp': '(strReceived)'}" as NSString)
}

Any guidance for how to call the function once its set up?
I'm trying to read data from one of the digital pins. It's being serial.printed in my arduino code at a 30s interval.
