I've just upgraded from a Denon to a Lyngdorf MP-60. I had feedback of volume and surround mode working perefectly with the Denon but I need some help writing a script for the Lyngdorf. The IP control protocol is available on their website and all I want is feedback of volume and surrounf mode. Where do I start? Thanks!

By the way I would pay someone if they could write this script for me!

How much and who maintains ownership of the script? You are looking at a mimimum of 8 or so hours work.

If you want someone to give you a quote, can you please provide the link to the protocol document here.

Hi Lyndel, I don't mind who owns the script. The link to the document is here [Link: lyngdorf.steinwaylyngdorf.com]

Thanks for providing the link. I reviewed the protocol specification. It is fairly easy to do but as I suspected to make a 'product' out of it, there is more than 8 hours and since I don't have access to the equipment for local testing, I have to pass.

Hoping others might be interested as could be a really interesting project.

Also, did you try searching github or google to see if anyone's already done something?

Are there any pointers to any similar code that I could look at so I could have a go?

The communication protocol uses message frame ending with a Carriage Return (CR) (ASCII 013) (\r).

This is very similar to the denon protocol. Not sure if there is any ready-to-paste example here in this forum.

So hacking around with Denon code I've got the Lyngdorf displaying the volume on the Pronto Pro, my only issue is the string that the Lyngdorf outputs is (e.g if my volume is -20.5) "!VOL(-205)". How can I clean that up so it just displays -20.5?

You can use a RegExp to match the string or use String subString to extract the "-205".

The end result is you need to convert this value to an integer and divide this value by 10 and display using toFixed(1).

var textThatHasBeenExtracted = "-205";
var int = parseInt(text,10).toFixed(1);

This is where you need to find a good RegExp and JavaScript reference such as W3Schools.

I've had a look but I wouldn't even know where to start putting this in to the code.

Hopefully this will help get you started.

Go here:
https://regex101.com/

Plug in this in for the Regular expression which follows the PDF for receiving ! or # depending on whether the message is a response or an event. Not going to belabor the point here as hovering over the regex on the site above does a great job of explaining what each thing does.

^([!#])(\w+)\((\w+)\)$

Then, put this in for the text

!MVOL(250)

You will get multiple matches which are presented in java/ProntoScript script as an array.

So, to write this in a button in your config, you'd add the following script.
var PATTERN = /^([!#])(\w+)\((\w+)\)$/;
var messageFromEquipment = "!MVOL(250)\r";
var withoutCR= messageFromEquipment.replace("\r","");
var matches = PATTERN.match(withoutCR);
// To debug this in PEP2 going to the ProntoScript console, add.
System.setDebugMask(9);
System.print(matches[0]);
System.print(matches[1]);
System.print(matches[2]);
System.print(matches[3]);

Thanks Lyndel, I put some time in yesterday working out exactly what the Denon code was doing. I’ve managed to pull in all the data I need from the Lyngdorf into the Pronto. I managed to format the volume using the range finction in the substring command and splitting it in to 2 labels so as I didn’t have to do any maths on it.

Not the most efficient but it works. :-)

You know I’m still so impressed with the 9400. Theres no other remote on the market that I know of with the form factor and hard buttons, 2 way comms, the power of the extender and the infinite customisation that I know of.
