ESp32 SD-Card Reader with USB BLE or WIFI

[stefan.erni]

Hi Ben

The ESP32 and SD cards work very well and very reliably with Flowcode11.
Recordings run for hours without any problems.
USB and BLE works also perfect (I haven't tested Wi-Fi enough yet).
Until now, I’ve always had to remove the SD card from the device and insert it into a card reader.
But that's not ideal for my device.

Question: How can I easily read the card via USB, BLE, or Wi-Fi?

The best option would be USB software such as aUSB card reader
