Thanks for taking the time to answer.

I'm pretty much doing as you say. My goal however was to modify the uC behavior using a data file that arrives in the Downloads folder.

Unfortunately, when GUI-O is running, I cannot find a way to move the file. If GUI- O is running, doing anything else loses the Bluetooth connection

What EXTF command structure would allow GUI-O to read/write TXT/CSV files to the DOWNLOAD folder?

THANK-you kl3m3n.

The changes to designer significantly reduce development time, and the @fileinit command moves configuration commands to the Android device and out of the microcontroller flash memory.

Great work. E.

Thank you kl3m3n.

I will test and post my reply asap.

One more question about using GUI-O on Chromebook tablet.

I've written commands to use a set of widgets from a uC to an Android phone. Everything works perfectly. The system also creates a log file by writing a line to an opened *.txt file every 2 seconds. I can retrieve the file from the folder /Android/data/com.guio.guioapp/files/Sample_1234.txt ---- exactly as described in the gui-o_developer_manual.pdf.

I now moved the same widget setup to a Chromebook. Again, all the widgets and functionality work perfectly.

The only issue is that the log file is not saved in the directory /Android/data. In fact, the folders com.guio.guioapp/files/ along with the *.txt file are not created.

The setup and use of the log file is simple:

"|EXTF UID:extf1 HID:extf FNA:'Sample_1234.txt' FAC:0 DTF:'MM/dd/yy HH:mm:ss'"

... with a log file text line written every 2 seconds using:

"@extf1 FAC:1 FP:'1.0 2.0 3.0 4.0 5.0'"

... and on exit:

"@extf1 FAC:3"
"@clh"
"@quitapp"

All permissions have been allowed on the Chromebook for the GUI-O App.
No errors or warning given at any time.

Any advice from an experienced user? Help or suggestions will be appreciated.

Thanks

EDIT: [ Solved ]

Unlike the Android phone, the folder /Android/data/com.guio.guioapp/files/ is HIDDEN along with the files created by GUI-O.

Get a good "file explorer" from Google Play Store, give it permissions to open hidden folders and .... VOILA ....

@kl3m3n said in Can widget configuration commands be sent directly to App from a file.txt?:

Regarding the .txt initialization file - this is actually a good idea. Microcontroller could just request initialization based on the pre-defined initialization file that resides on the Android device side.
I will think on this a bit more, but it seems a good feature (I will let you know about this...).

YES .... This is exactly what I had in mind.

Something similar to consider, although minor, could be showing info from the mobile phone directly onto a widget. For example at the moment, to show the actual time, the uC has to receive it from the RTC, then echo it back to a widget. I could see a widget that's configured to show the time directly -without the round trip.

Regarding moving the widgets on the screen with Designer, as long as the final config can be saved as an unencrypted (*.txt) file, that should be fine. I had in mind something like PowerPoint but much simpler.

Let me know if you need help with beta testing.

GUI-O_Widget_Setup.Apr8.23.txt

Hello,

I've developed a BioFuels Distillation training simulator. The widget configuration commands are included in the attached file. I would like to share some feedback:

1. Once the widgets are set up, the I/O and response to the App is very easy, intuitive and provide terrific functionality. Good work!

2. One problem however, is that these widget commands occupy a significant amount of memory in the microcontroller. This seems inefficient.

One thought was to save the commands in a *.txt file, have the microcontroller read and send them to the GUI-O App. (Unfortunately, I was not able to get the EXTF command to respond clearly to requests to read a specific and complete line from the file.)

3. A second, time-consuming and somewhat frustrating task was placing the widgets in the desired location on each of the 5 screens.

While the GUI-O Designer is helpful, unfortunately it too needed a significant amount of time to find the correct locations.

Since the mobile phone is always connected to the Designer App, would it be possible to have the user move the widgets on the screen (to the desired location) and have Designer save the setting in a file.txt?

Nonetheless, GOOD WORK.

@kl3m3n Thank-you.

That's what I needed.

Does anyone know how to run GUI-O on an Android Chromebook?

Hello,

We currently have a battery-operated uC-based unit that has its own display unit. We would like to consider the possibility of providing our clients with an option to use GUI-O to show real-time data from the unit.

Can the GUI-O application we've developed be "compiled" and offered through MS Store of Google Play for our users to download?
