Hi everyone! I've been working on integrating M5Stack with a logistics system to streamline shipment tracking. Using the M5Stack Core2, I managed to create a real-time dashboard that monitors package locations via APIs. This is similar to how platforms like TraceShipments work, where live data is updated and displayed for seamless tracking. Has anyone else experimented with using M5Stack for logistics or tracking systems? I'd love to hear your experiences!

I'm glad to hear the issue is resolved! The SD card initialization step is indeed essential. For future troubleshooting, make sure the SD card is properly formatted and always include the initialization code in your sketch. If you run into similar issues, checking for hidden characters or formatting errors on the card can also be helpful. Thanks for updating us on the solution!
