Could the GUI-O Designer be made to work with WiFi?

SteveV

Hi,
I'm new to GUI-O and working my way through as many of the examples as I can in the limited time available.

I have successfully exercised the Live Design on the PC to control GUI app on a Samsung tablet via the ethernet mode. Works great!

I'm working on a project that I wish to make an Android tablet into a data entry terminal, and the Samsung would be suitable but an overkill.

I purchased a cheap Android tablet (ATMPC IT-1001A) that is marketed for kids - and has limited functionality, RAM etc but I think will be enough.

Unfortunately the ATMPC doesn't support ethernet, and I'm not able to design an app using the GUI-O Live Design with it.

It works great as an IOT device (with an ESP32-WROOMD WiFi module).

I'm not aware of the limitations, inabilities or complexities involved, but could WiFi connectivity be added to Live Design?

That would neat .......... !!

Cheers,
Steve

@SteveV Hi!

I am not sure I understand...

If the device has WiFi, it can connect to GUI-O designer... This is how the "Ethernet" example works.
So your tablet should connect to the designer. Just specify the IP of the interface on you PC and use the same IP with GUI-O on the tablet...

How did you do the example on Samsung tablet then?

@kl3m3n Hi Klemen,

Let me try to explain:-

Run GUI-O Live Designer on PC and entered PC IP and selected Port 50000
On ATMPC tablet:
2a. Run GPI-O application
2b. -> Add
2c. -> Add new device
2d. -> Select 'Ethernet'
2e. -> Enter 'New"
2f. -> Enter new device name and press return
2g. Screen returns to that at 2f. with message showing
'Invalid Input'

Neither the Device IP or Device Port can be selected (if attempted, screen returns to 2f. but doesn't have an 'Invalid Input' message)

So I'm at a loss on how to setup a device on the tablet that will make the connection with the PC (IP) running GUI-O Live Designer.

I had followed the same procedure with the Samsung tablet and a new device is able to be setup and it works with the Designer.

So the question is - how can I make the WiFi only tablet connect to the GUI-O Live Designer when I can't make a new device with an appropriate Name/IP/Port?

Cheers

@SteveV This seems to be an issue with the input for your specific tablet. I am afraid that I cannot do much to fix this.

Try navigating under Android settings -> Additional settings -> Languages and input and check if you can select another input method (another keyboard). You can probably download something from the Google Play (just to test this).

You could develop your GUI on Samsung tablet and then just use the same initialization string for the other tablet.

I could probably also upgrade the App and Designer to use a QR code to pair (no need to enter the IP / Port parameters manually). But I am a bit reserved about this - the Ethernet connection type is a general way of communication, it is not intended only for Designer tool.

@kl3m3n Hi,
Thanks for reviewing my issue.
I have resigned to the fact that the cheapy ATMPC is probably not going to work with the 'ethernet' connection, and have taken on your suggestion to do the development on the Samsung and use the initialisation strings on the ATMPC.

I tried a test UI created on the Samsung using the GUI-O Live Designer, copied the initialisation strings into modified ESP32 code, created a new IoT device on the ATMPC and - Bingo! - worked a treat.

Thanks very much
Cheers
Steve
