Hi to All

I ran a test on Ben's board and used the loop to initialize the card every 10ms .
I didn't use an SD card, but I checked it with the KO, and the signal was perfect.
Then I switched the clock to a free port (GPIO 19 and GPIO 20), and the clock was perfect there, too.

I added the same ...

Hi to All

There is one remaining issue that I have not yet been able to identify or resolve.

The FC11 fails to initialize the SD card on this board.
However, the same SD card operates reliably with FC11 on other board, such as ESP32-S3 and ESP32-WROOM boards.

Interestingly, similar issues can ...

Hi Martin

That's interesting what you're doing.
I'm also trying to put an S3 into deep sleep right now
I'm guessing the name “Zero” comes from Waveshare.

Yes, depending on how the USB connection is used, you may need to manually put the board into bootloader mode. To do this, press and hold the ...

Hi Ben

The SD card works with the old SD component, but I don't have any free SPI buses left because of the display and the AD converter.

I'm having trouble with the C code insert from You.

Does it just need to be in a C code component, or should it be added as a supplementary C code?

Hi Lian

I started with a 10-meter test, and it worked without any problems.
For longer distances, I have to go outside.

Hi Lian, Hello everyone

Sending with the ESP32-S3 worked right away.
I just used the macro and added the Wi-Fi

I don't think this easy way is available for the WEB App....

Later, I'll also test the Wi-Fi range

Hi Lian, Hello everyone

I wrote a simple server and client program to send data from one Flowcode program to another Flowcode program .
It works with strings and byte arrays.
Maybe it will also work with an ESP32 over Wi-Fi.

Hi Lian

That's what I'd like to have.
I did not realize that I didn't necessarily have to link the Network Comms component.
I tried sending a string from one Flowcode program to another Flowcode program,
on the same computer, using the Network Comms, and it worked fine.

I'm going to try ...

Hi Lian

Thanks for the information.
I assume you mean the MQTT client. Yes, it's practical and convenient for measurement data and is also very well documented.
You can install your own local broker or use one from the internet.

Hello everyone,

I would like to propose a new Flowcode component: TCP Sockets (Client and Server), Embedded and PC-App (Web-App?)

With the increasing use of Wi-Fi-enabled microcontrollers such as the ESP32, many projects require reliable communication between embedded devices and PCs over a local ...
