Strange, this command works for me... You are terminating the command with new line, i.e. '\n'?

Can you try sending @sori1 ORI:2\r\n after creating the component?

Currently, no, it is not possible.
I will see if i can make a "toggle visibility" option for the next release.

You can do one of the following:

Clear the app data from Android settings (settings - apps - GUI-O - clear all data). Note that this will clear everything, even stored devices.

Follow this link on GUI-O website:
https://www.gui-o.com/examples/gui-o-and-boards/esp32#h.7e5a31l59xj
Download the example and check the credentials in the code near the top. You can use port 8883 for secure communication, or 1883 otherwise. Client id can be empty, in this case GUI-O selects a unique generic client. You can also set it to your unique username.

Best regards,
Kl3m3n

Hi Bob,

sorry for the late reply!

Wow, 65 years of experience... I can't even imagine all the challenges you've tackled over these years πŸ™‚

Of course I can provide an "organized" list of all widgets along with their properties. What would be the best format for you?

One thing I still fail to understand - what will you use for the actual widgets on the editor canvas? Some more generic widgets?

Anyhow, I think we should move this discussion to an email or some other channel. If you want, you can send the reply to: info.guio.app@gmail.com

Best regards,
Kl3m3n

@kl3m3n said in Connection status?:

Connection monitor (separate for each connection type). If the feature is enabled, GUI-O app requires periodic messages (e.g., ping) after first received message. Otherwise, it will disconnect and enter error state. I will also support that the feature can be enabled from the controller command.

Implemented. See the latest manual, section Connection monitor.
I did not support enabling / disabling the connection monitoring via the commands. This can only be done in-app.

@kl3m3n said in Connection status?:

Any error that causes a disconnect will clear the UI.

Implemented.

@kl3m3n said in Connection status?:

Add support for @disconnect command. This will make it possible to send a disconnect request from the controller side. This will also clear the UI. User can then reconnect via the "Connect" button on top-left part of the home screen.

Implemented. See latest manual.

@kl3m3n said in Connection status?:

Add some sort of connected indicator when connected and on home screen (no UI loaded).

Implemented. A small indicator in the top-right corner of Connect button (home screen) shows if device is connected (green dot) or disconnected (red dot).

Best regards,
Kl3m3n

I have sent the initialization code to your e-mail (I have included your full commands there, but not here on the forum).

Can you please test it and see if it works for you?

You can try extending sendCommandPeriod if you have any issues... Also you can comment out the @sls and @hls commands to see exactly what is going on...
