I’ve ran the “Check Status” example code, and repeatedly get this message in the serial terminal:
OpenLog Status Example
Status byte: 0x00
SD init failure. Is the SD card present? Formatted?
Root failed to open. Is SD card present? Formatted?
No log file open. Use append command to start a new log.
Done!
I’ve also tried the appendFile example code, but that doesn’t change anything mentioned above.
