X-CUBE-ST67W61 wifi with STM32 NUCLEO H723ZG

[mihirsinha_]

Dear Sir,

I am currently using the STM32 NUCLEO H723ZG board with the X-CUBE-ST67W61 expansion. I want to transmit the ADC values from the STM32 board via Wi-Fi. I attempted this using a trial-and-error method but was unsuccessful.

Could you please guide me on how to achieve this? I am completely new to working with X-NUCLEO boards.

I am sharing my code for your reference. Kindly take a look.

Thank you,

[mihirsinha_]

As for your question - to send any data over wi-fi usually you need to connect the wi-fi to some router (access point) then open connection to a server (TCP or UDP) and create a network socket. The documentation for the  X-CUBE-ST67W61 should cover the details.

Hi @mihirsinha_ 

Yes, the ST community can probably help you, especially if you describe precisely what your Wi-Fi application will do, which protocol you plan to use among HTTP, MQTT, etc., examples of which you will find in the X-CUBE-ST67W61.

Have you already implemented the ADC configuration, as I don't see it in your code that you shared?
The ADC should be the first step in your project, in order to validate that the datas you want to transmit meet your expectations. This is already a big job. After that, you can integrate it into an existing Wi-Fi example.
Here are some resources that may be useful to you:

You can also refer to this example for the STM32H735G-DK, which works perfectly with the NUCLEO-H723

As you indicate that this is your first time using X-NUCLEO boards, please also make sure to carefully read the STM32H723 documentation (reference manual and data sheet) and the board user manual:
https://www.st.com/en/microcontrollers-microprocessors/stm32h723-733/documentation.html

https://www.st.com/en/evaluation-tools/nucleo-h723zg.html#documentation

Without a doubt, once you have shown that you have devoted time to your project (because no one will do it for you) and if you are now encountering real difficulties, then the members of the STM32 community here will (for sure) certainly be able to help you.

Good luck,

Best regards
