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

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,
Roberto

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.

Hi @cryptospok .

Hi @cryptospok .
In my tests, I received that error when there was a conflict with the I2C address.
I used Uiflow V1.13.6; it’s a short text for 2Relay, and I also had trouble finding it.
I’m sending you the modified version that includes storing the I2C address in EEPROM.
If you need to save the state of the relays, you can also store it in memory.
Saludos
Roberto

Hello @cryptospok :
It worked well on my hardware. In the example I will send you, you can alternate the address between 0x25 (default) and 0x30. If the M5 is disconnected while the address is set to 0x30, you will have a problem.

This can possibly be solved by writing the address to the EEPROM and retrieving it at startup.

Best regards,
Roberto.

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

I wanted to edit the first message to change the title to “resolved,” but I can’t seem to do it.
Do you have any ideas on how to solve this?
Thanks,
Roberto

Hola @felmue

Now I did it but it can't be done!

@felmue
Hi Felix, I haven’t been able to change the title.
I saw your GitHub page, it’s clear that C++ is your language.
Thanks for providing me with the UIflow example.
Roberto.

@felmue
This has worked perfectly thanks to your help.
Your comments helped me understand the code and adapt it to my needs.
If there's any way to mark this post as resolved, I would appreciate it if you could let me know how to do it.
I am very grateful for your help.
Thank you so, so, so much.
Roberto.
