I am trying to store data on a sd card using TTGO TCALL SIM800L module.
The rSD library allows reading and writing to SD cards. The Ethernet shield as well as other shields include a SD slot. The steps required to work with files: 1. Initialize a SD object. You need to pass the CS pin used. See this link for more information...
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.

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?
