I am trying to store data on a sd card using TTGO TCALL SIM800L module.

The SD Card is formatted with FAT32 and stores two files:
rates.dat
log.txt
When making the connection it detects the list of files,but it is not possible to read the content of the files.

Log:

AppStart
/System Volume Information    0kb    1
/log.txt    0kb    0
/rates.dat    1kb    0
Error opening file.

I have tried creating a directory with:
sd.MKDir ("agc001.txt")
but don't believe it.

According to the documentation, this is the pinout of the TTGO TCALL:
VSPI_MOSI = 23
VSPI_MISO = 19
VSPI_SCK = 18
VSPI_SS = 5
I'm using sd.Initialize (5)

Which default pins does rSD use?

what is the problem?
Thanks for your help!
