@kl3m3n
Here are the test results you requested. Everything looks normal to me and there does not appear to be any reason for the CB control to snap back to 100% but it always does.

1.) Reset Nano, and serial prints:
Bluetooth® device active, waiting for connections...

2.) Start GUI on phone and serial prints:
Connected!

3.) Click large center connect button of GUI on phone and serial prints:
Parsing . . .
GUI-O app is requesting INITIALIZATION!
and phone displays the Light Off image

4.) Click TAP ME! and serial prints:
Parsing . . .
GUI-O app is requesting LIGHT ON!
Just set CB to 100%
and phone displays Light On image and CB control at 100%.

5.) Tap near the center of CB control and when release the serial prints:
Parsing . . .
GUI-O app requesting Brightness change!
GUI-O app is requesting LIGHT BRIGHTNESS: 45
and the phone displays the CB control at 45% as long as I hold it but when I
release it the LED reduces brightness like it should but the CB control snaps back to 100%.

6.) Trying a 2nd time, tap lower on CB control and when release the serial prints:
Parsing . . .
GUI-O app requesting Brightness change!
GUI-O app is requesting LIGHT BRIGHTNESS: 16
and the phone displays the CB control at 16% as long as I hold it but
when I release it the LED reduces brightness but the CB control snaps back to 100%.

7.) Trying a 3rd time, tap low on CB control and when release the serial prints:
Parsing . . .
GUI-O app requesting Brightness change!
GUI-O app is requesting LIGHT BRIGHTNESS: 5
and the phone displays the CB control at 5% as long as I hold it but
when I release it the LED reduces brightness but the CB control snaps back to 100%.

8.) Exit the GUI on the phone and serial prints:
Disconnected!

9.) Using PC Explorer open in_messages.log file to get:

To me the Log shows everything is working correctly but the CB control on the phone always jumps back to 100%.
I have 14 sec video of above but it won't let me upload it (too big).

Hope this helps

Hello @kl3m3n,

The read how many lines exists in the files is no problem.
Next week i will see how to handle it with FAC and FP

Thank you
Regards

@enniom Hi!

Currently there is no such feature to store the files outside the application folder. I will take a look into this a bit after I make some necessary adjustments to fully support targeting Android 13.

Your changes work great! THANK YOU for the quick response and new parameters in CB

@enniom Thank you. 😁

Hi @kl3m3n,

Thanks, I know this chip, but never used it

I have done in the last 20 years almost all my projects with Bascom and Atmega and Xmega microcontrollers, but there are no libraries like in the Arduino, you have to code everything from scratch. With the Esp32 this task is easier, for this there is the lib can.h and you only need the soic8 driver for the bus.

The advantage is that the Atmega88PA is cheaper than the Esp32 but I will still think about which one to choose

Thanks for the attempt to help

Regards

Hi Kl3m3n,

A sincere thank you.
The whole process seems to be quite complex. In my case, it is for Windows.
I am trying to get a fixed IP. The ISP operators want a high value. I will look for cheaper ones.
In the next few days I'll try to install it and do some tests. I will give you my feedback then.
Thanks again for your support.

Best regards

Hi @kl3m3n,

Not see it, thank you
In a few days i will test it and give feedback

Best regards

@enniom Thanks for the feedback!

@Sato Hi!

Google has strict policies regarding sensitive permissions (SMS included).
In order to handle SMS related functionality, the application needs to be (in general) registered as the default SMS app. Since GUI-O does not need SMS functionality to run, it would be probably quite impossible to convince Google to allow SMS features in GUI-O. You can read more about it here:

Hi @kl3m3n,

Thanks, I really have to change my glasses

@Bernard Very nice!

Thank you for sharing!

BTW, was your wife happy with your answer? 🙂

@Bernard
In your Sub, the Return statement is used twice. Maybe that's the problem.
After first return statement must be:
Guio_ini_2:

@hls 250 should be at the end of the Init procedure.
I checked the Init process without the Bascom code and it works OK.

Maybe put |CH

|CH UID:ch0 X:50 Y:75 W:50 H:50 XLO:0 BSZ:120 VLP:2 BGC:#E53A4456 FGC:#EF33EAF5 SHE:1 FSZ:2.5 RAD:1 CHT:2 CHN:'MESURE HUM / TEMP / PRESSION' XTC:12 YTC:6 YMA:4 XMA:2 XHI:75 PZO:0 @hls 250

just before @hls 250

Otherwise, your GUI-O screen is very nice 👍
