Greetings, Thank you for that information. But, I am not clear as to how to initiate an connection to,?and or the ability to exchange data to and from the SD Card which is installed into the NanoVna_H4?which I have. I did not notice any change of the device screen indicating a connection was now possible.?Also, I didn't notice any fields located in NanoVNA-saver application on my windows 10 PC. Must I install,?or re-install device firmware in order to affect the change that I have made by accessing the card slot.?Thank You

For read file need
sd_read {filename}
After nano return binary file data
or on error
"err: no file\r\n"
Delete file:
sd_delete {filename}
After nano delete it from SD card:
Output
shell_printf("delete: %s %s\r\n", filename, res == FR_OK ? "OK" : "err");
