4998 is the port to use.

Correct - the subscription only relates to use of the Designer software. The app would continue to work, regardless of the subscription status of the Designer software used to create the project.

I understand this has been resolved via DemoPad support email - which is the fastest way to get help.

Yes this is expected, the Centro does not act as a telnet server, it typically acts as a client to control other devices

Feedback issues are often caused by having the wrong response terminator, ie the last character(s) of data sent back from the device. Try confirming with Hercules what this should be, and also confirm that if you populate your label manually with some data, that it appears.

Presume you mean \x0D\x0A as the suffix, not \x0D\X0A Try changing the IP address of the device to match your PC, and use Hercules in TCP Server mode to see what data comes in, and compare with what you send yourself from Hercules. Usually you need an extra \x0D\x0A at the end of the command. Does t...

Subpages can scroll via a swipe, which is the usual approach for this kind of thing - please see http://designer.docs.demopad.com/pages/subpages/

When forming a url, you need to use $20 for spaces, which is the problem, as your retrieved feedback will contain actual space characters which are invalid url characters. In the next version of the CentroControl app, the 'send data to website' action type (which you can use for GET requests requiri...

The Bad Request response above is likely because you are using \x instead of $ for the hex characters - Hercules requires that you use $0D instead of \x0D - suggest using text rather than your online hex converter, which will be taking \x0D\x0A and treating it as 8 characters, rather than the 2 it s...

Ok - next thing to try is Hercules in TCP Client mode to see if you get the same behaviour. Note Hercules uses $ instead of \x so use $0D$0A instead of \x0D\x0A A few things I note in your commands though, after the Content-Length, you have \x0A\x0A - I would expect this to be \x0D\x0A. Plus the Con...

Method 3 is the easiest approach, and you look to have it set up correctly. You can test using Hercules in TCP server mode, port 80 listen, and alter the IP address of the device in Designer to match your PC. That way you get to see the commands coming from the app in order to confirm they are corre...

Not as such, but you can group pages and subpage into your own folders, which helps with organisation.

This appears to be the case when the sizes of objects are different between portrait and landscape, and the portrait view takes the landscape sizing by mistake. An update will be available shortly to resolve this, it only affects the Android app, and only when the same mirrored object has a differen...
