In Spain, it's not working. A few days ago, the server was down for more than 16 hours.

Hi @teastain .
I don’t know how to program in C++, that’s why I have fun with the Uiflow blocks.
I am very grateful for your intention to help me and I will try to test the code, although modifying it will be my problem.
Thanks

@felmue Hello , Your code worked perfectly. I really appreciate the time and effort you put into helping me—it means a lot! Thank you!

[link text](link url)Hello everyone,

I'm facing issues with both subscription and publishing in MQTT. When publishing, it does not allow me to send alphanumeric values. If I use a numeric string and then convert it to an integer, it works correctly, as shown in the following example:

MQTT publish topic "coreS3/state", "5", Qos 1

However, when I try to publish any variable, whether numeric or text, the system simply ignores the command without displaying errors. For example:

MQTT publish topic "coreS3/state", numeric or text variable, Qos 1

If instead of a variable I use a fixed string, the command executes without issues.

I have spent a lot of time trying to solve this, but I haven't found a clear answer. Has anyone faced a similar issue or has any suggestions on how to fix it?

I appreciate any help you can provide.

Hi@neus-morla ,
If you have the device as it came from the factory, try this:

Download M5burner.
Log in.
In core, look for UIFlow_Fire; this will flash the updated firmware (this might be the problem).

I am working on a project that requires wireless communication between a StickC Plus and an M5Core Basic using the ESP-NOW protocol. I am new to this and would greatly appreciate it if someone could provide me with a simple example to establish this communication.

I have found some tutorials on ESP-NOW, but I would like to see a specific example for these devices. Any help or example code would be greatly appreciated.

In other tutorials, it is also happening.
I tried with Chrome and Edge browsers.
It would be great to be able to download a PDF with the class.

Hi @felmue
Friend, thank you very much for your interest in our problems.
Cheers.

Hi @cryptospok .
I’m glad you resolved it. I also experienced the frustration of not being able to solve the problems and seeing time pass without finding a way out. Fortunately, Felix was there to advise me and provide an example that I could adapt to my needs. Good luck with that project, and we’ll meet again around here.
Until next time,
Roberto.

Hi @Zoidberg ,I spent a lot of time trying to log in to Uiflow1, but I couldn’t find a solution.
Best regards,

Hi @cryptospok
“It is correct that it gives you 1, it is the firmware version (I have the same version), now you can breathe easy. In the example I sent you, change all the 37s to 102 and the texts 0x25 to 0x66. It should work.
