DEV-15164 Qwiic OpenLog Can't Write to SD Card

Qwiic System
1

Using this Qwiic board with a Sparkfun WRL- 15663 Thing Plus.

I am able to myLog.begin() and get a return value that it was successful. I have been following the Example 1 for the Qwiic OpenLog.

I have successfully created a 8.3 filename of “HBLog.csv” on the SD Card.

I have successfully created a long filename of “HumidityBoxLog.csv” on the SD Card.

I use the myLog.print/println procedures per Example 1 along with the myLog.syncFile() procedure to write to the SD Card.

Nothing is written to the SD card.

The SD card is a ScanDisk 4mb, Micro SD, HC.

Please advise,

John

I should have also said that the SD Card is formatted as FAT32.

I ran Example 1, and nothing is written to the card.

Can I get some help on this issue?

Try this filemanager . https://github.com/paulvha/apollo3/tree … ilemanager

It was developed for Artemis, but I have just tested on an ESP32 thing plus and it works.

With option 11 you can add content to a new or exisiting file.

I’d try a couple of different cards and see if one of those work.
