@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

Here is one example of adding an Eyra electronics MPPT-100 MPPT solar charger remote control device.
[https://www.eyra-elektronika.si/solarni-regulator.htm](link url)

It's a great product, now I can control it remotely via WiFi and GUI-O.
I use the RS232 port to communicate with the device.

Check the communication lines. Be careful not to connect the RX and TX pins of the ESP8266 together with the Rx and Tx pins of the Bluetooth module.
I generally use ESP826612F in SMD or Wemos D1 mini version. Sometimes it happened that some information was missing in a very long text. I solve this problem by separating the sent text in two messages on ESP.

It may also happen that the ESP does not work properly and needs to be replaced with another one.

It is possible that you are using a While - Wend loop that never ends because the Sig_Sim parameter is always "0".
Check your code and change the Sig_sim variable to 1 at some point during runtime.

Maybe you should try changing the While - Wend with an IF - ENDIF statement.

Alternatively, maybe modify Ischarwaiting() with serial interrupts something like this:

On Urxc Rxcom1_isr
Enable Urxc
Dim Rxdata1$ As String * 80
Dim Rxdata As Bit

Dim Comchar1 As Byte
Enable Interrupts
Do

If Rxdata = 1 Then
Reset Rxdata1
Print Rxdata1$ 'do something with your received data
End If
Loop

Rxcom1_isr:
Comchar1 = Inkey()
Rxdata1$ = Rxdata1$ + Chr(comchar1)
If Comchar1 = 13 Then ' detect end of line can be 10 or any other char.
Set Rxdata
End If
Return

, but it will completely change the concept of your code.

Hello.
There is an example Bascom GUI-O Datalogger made on Arduino Nano/ Bluetooth HC06 and GUI-O android application for measurement temperature and humidity using AM2301 sensor.

GUI-O application
https://play.google.com/store/apps/details?id=com.guio.guioapp
or
www.gui-o.com

Application store data in the smartphone, directory
Code:
\Phone\Android\data\com.guio.guioapp\files\

SD card and big processor not required on electronic site.

Sharing and opening file is also possible direct from application. On phone screen type on filename and opening external application to open stored file.
Typing on text »Datalogger« performed Init procedure again.
Type on label www.gui-o.com to visit this for more details.
In case that temperature is less then 0 C a warning appears - Vibra and tone from smart phone
In attach is source code, schematic, Prenos.gif picture, which is needed to copy in directory to Android smart phone in the directory:
Code:
\ Phone \ Android \ data \ com.guio.guioapp \ files \ Pictures \

When the button “Start Logging” is pushed, GIF animation start.
NOTE. When you program Arduino via USB (bootloader) it is recommended that disconnect Rx and Tx pin to HC06.

There is also Youtube video.

@kl3m3n
Thank you. Now it works.

Here is a screenshot of my android phone for the snail trap.

I would like to make an A-meter whose scale is almost half the screen. The problem is that the CB W: (width) is limited to 100%.

Is it possible to increase this value?
Attached is a picture.

Here is my screenshot of GUI-O GSM parking system management.

Graphical interface (Android screenshot) entirely made with GUI-O.
https://www.owon.com.hk/products_owon_4_1|2_digits_xdm1000_series_bench-type_digital_multimeter

... and HW connected to the serial connector.
It can be connected via WiFi or Bluetooth to a smartphone.

@VNB said in GUI-O with Nano 33 BLE and the ArduinoBLE Library:
