Does anyone tried wireless SD card on Arduino before?

Hello guys, I wanted to do some wireless .txt file transfer between 2 embedded system (In this example, from Arduino to Windows laptop).

I knew some people were doing this using two Xbee on each side, but has anyone tried using wireless SD card before? I am not sure whether it will work as I know, wireless SD card is usually used in camera devices only, and mostly only support picture/video file format such as jpg, mp4 etc.

If it will not work, what is the best way to make a wireless transfer? Appreciated if anyone could provide some advise on these! :wink:

If it will not work, what is the best way to make a wireless transfer?

The typical questions are:
What range?
How much data?
How often?
How reliably?
How much can you afford to spend?

Look at your post. See how many of the questions you answered.

A link to the datasheet for the wireless SD card that you propose to use would also help.

  1. 30m indoor without obstacles should be fine.
  2. The data is expected to transfer in .txt file, around 2MB each.
  3. It can be either a loop to send and receive continuously every minute, or we send it whenever we need the data.
  4. Well, I'm not sure how to define it as super reliable, it is fine as long as the file can be transferred successful.
  5. I'm expected to spend $35~$40 if going for a wireless sd card. But of course, the cheaper the better.

Currently the weather station I am working on, we transferred the weather data file by removing the sd card and plug into PC.

I've attached the product specification in the previous post.

Wireless SD card is usually used in camera to transfer photo to pc/phone, and it require some software or apps to function. In this case I think it is not feasible to use SD card with built-in Wifi on Arduino. Will try to search on other option, thanks for the advise btw!

Your datasheet has a lot of detailed information but lacks an overview of how to use the product. I think it requires the host device to send commands to the card to get it to transmit data using WiFi. I have no idea whether an Arduino could do that, but it may not be much different from (say) using an ESP8266 module for WiFi.

Given the very small size of the device I suspect its wireless range would be short.

No matter what system you use it will take a long time for a 16MHz Arduino to send 2MB of data if the data has to go through the Arduino byte by byte. For large data quantities a RaspberryPi might be a better choice.
