Cyw43 on STM32H723

I already managed to get my NUCLEO-H723ZG to boot up and so some basic things.
I saw online the Ezurio 453-00376 with the Ezurio 453-00141 card for it (specifically made for NUCLEOs), and wanted to give it a go.
I'm using embassy so getting Wi-Fi to work should not be that much of a problem (I want to use it via SDIO and from what I see the crate supports it).

The problem

The Ezurio board I want to buy only supports SDIO and UART, so my question is, did someone managed to get both Wi-Fi and BLE on SDIO or should I use UART HS for bluetooth, passing it directly to trouble?

One of my concerns is that if I use them separately (SDIO for Wi-Fi and UART for BLE) I should find a way to send both the required firmwares still.

It's my first post on this forum so please don't blast me :folded_hands:

while this forum is for all rust related topics, you are more likely to get a quick response for problems questions about the language itself, such as questions about syntax, compiler, cargo, things along these lines.

for certain problem domains, while waiting for the right people to see your post in this forum, you may seek help in dedicated communities of smaller scope, where people are more focused on and specialized in that specific area.

the cyw43 crate is part of the embassy project, so I would assume it integrates seamlessly with the ecosystem, but I don't have any personal experience of this hardware, so I don't actually know the answer.

meanwhile, I suggest you go to the embassy chatroom to ask the experts there. another place to go is the rust-embedded chatroom. there you might have better chance to find a person with the right knowledge for your question.
