I am happy you find the improvements useful!

Thanks.

@SteveV Hi!

You mean you cannot enter IP address due to not having any period ('.') character available?

This is not normal. Can you try changing the keyboard from Android settings and see if the issue persists?

I am "forcing" the number keyboard when user touches the IP field... In most cases, the keyboard also shows other characters. Anyway, I will fix this ASAP - I have a release lined up right now. I will probably take a day or two...

Best regards,

@Bernard Yes, you have wrong credentials. This is what's causing the problem. You have changed the settings somehow...

I advise you to clear application data or uninstall and reinstall the application. This will reset the settings to default. Alternatively, you could input the correct settings, but I recommend reinstall... It will be easier for you. Then retry pairing.

Note that you must keep the default settings if you want to connect to GUI-O server!

@Bernard I am glad that you've solved it!

@gammda has made some great projects in the past, so he is definitely a GUI-O expert!

@etravnik Hi!

Can you please tell me which connection mode you are using (Bluetooth, IoT...)? Can you provide a minimal example which reproduces the problem?

Hi!

@Bernard said in ESP8266 bugs !!?:

They worked without problems for months and suddenly, the two applications no longer want to connect to GUI-O!

This is very strange! Does the ESP8266 Wemos D1 R1 have a serial debug port? Can you check out what is happening there? You would need to change the config.h file and uncomment #define _GUIO_DEBUG to see the output on the serial. Then recompile and flash the ESP8266.

@Bernard said in ESP8266 bugs !!?:

I see that GUI-O connects to the application but the data exchange only partially works!

Can you explain what "partially works" means? The serial debug option would also help you here to diagnose what is happening.

@Bernard said in ESP8266 bugs !!?:

Is there software capable of restoring the original firmware in the ESP8266?

What original firmware? Is which software capable of restoring the original firmware? You can erase ESP8266 flash - there are a lot of online tutorials to do this.

Note that if you have already performed the pairing, the pairing data is stored in EEPROM. You can clear the EEPROM pairing parameters (and thus reset pairing) by sending command (you may need to send it twice):

!CLEAR_PARAMS\r\n

to ESP8266 (see https://www.gui-o.com/examples/gui-o-and-boards/esp8266#h.wojc1r2r0dkx).

Please let me know how it goes.

@Sato said in Files on the Spiffs:

@kl3m3n, Hi

I think that can help. I will make experiments with it.

Can i choose the filesnames myself? If yes, how long can be the max name lenght?

Thank you
Best regards

Yes, you can choose your file name. The maximum lenght is not limited by the GUI-O, but by underlying file system and other constraints. I would say you could safely use name lenghts up to 127 characters, but this is probably not practical...

@Sato Did you se EXTF component in the manual? You can use this to save (among other things) data to a file on Android device. You can also read this file and send it line by line to ESP32.

It is not ideal way to transfer files, but should cover your case?

Best regards,
Kl3m3n

@Sato Hi.

Can you explain what are you trying to achieve?

Do you need to transfer the file from Esp32 to mobile device? Do you need the contents of the file integrated into GUI-O protocol?

I need some more information before I can see if what you need is even possible.

Best regards,
Kl3m3n

@Sato I will update the example, so it is compatible with the new esp32 version.

@SteveV No problem! Happy to help!

Best regards.

@SteveV Hi.

It seems that the API has changed...

Try using esp32 2.x.x version, until i update the example. I think you should be able to uninstall 3.x.x version and revert back to 2.x.x.

Alternatively, you could modify the "ledc" functions to use the new API.

Best regards,

@SteveV Hi.

Did you install the esp32 board support? Which version are you using?

Please let me know, so I can help you further.

Best regards,
