@sato Ok, I am glad it works now. The unicode sequence is parsed as double quotes, so it needs to be escaped again to not represent the actual escape sequence, but a backslash. GUI-O can then parse this correctly.

Thanks for the feedback.

@sato

Try escaping the \u0022 sequence using another slash, e.g.:

<font color=\\u0022red\\u0022>

Does this work ok?

@sato You are missing the escape character. Did this even compile?

Try (please try copy-paste) the following:

String var = "13:13 13-07-2022 Ewald Weber";
String message = "@ta1 TXT:\"<font color=\u0022red\u0022>" + var + "</font>\"\r\n";
mqttClient.publish(&In[0], &message[0]);

@sato Thank you, I will add it to the list (with low priority).

@sato

Could be something like this (after creating |TA with UID:ta1):

String var = "your_variable";
String message = "@ta1 TXT:\"<font color=\u0022red\u0022>" + var + "</font>\"\r\n";

in case of * delimiter:

String var = "your_variable";
String message = "@ta1 TXT:*<font color=\"red\">" + var + "</font>*\r\n";

@sato said in Know the UUID of the connected Gui-O:

Hi @kl3m3n,

appUserName works great. Thanks

Thank you for the feedback.

@sato GUI-O supports NFC, but this feature is currently disabled. I will enable it, but first I just need to think how to expose it to the user. Possibly through hardware components, similarly as RTC (real-time clock).

@sato Yes you can do it, but it takes a little "trick". There are two ways to do it:

1. Use double quotes for text (default). For example:

|TA UID:ta1 X:50 Y:50 TXT:"my text"\r\n
@ta1 TXT:"<font color=\u0022red\u0022>my red text</font>"\r\n

In this case, the \u0022 is unicode escape for double quotes, which needs to be written like this, otherwise GUI-O will parse the TXT incorrectly when adding the 'font' color attribute.

2. Use other character for TXT encapsulation (for example * - you have to set this via @gse request - see 'General settings change request' section in the manual):

|TA UID:ta1 X:50 Y:50 TXT:*my text*\r\n
@ta1 TXT:*<font color="red">my red text</font>*\r\n

Note that instead of "red" you can use any hex color, e.g., #FFFF00.

This is not explicitly stated in the manual, so I will correct this.

@sato Hello. The feature is implemented in v1.0.14 (should already be available). See the new manual under 'Application user name' section.

@sato Hello,

I have fixed a minor bug in the app and plan to release a new version. I will see if I can do something about your suggestion.

Best regards,
