@naofuruta The issue with the timestamp being set to 2075 on photos taken with V-Training is likely due to a firmware or configuration problem. Here’s how you can fix it: Steps to Resolve: Update Firmware: Ensure your M5StickV or the device running V-Training has the latest firmware installed. Outdated firmware can cause incorrect timestamps. Download the latest firmware from the M5Stack official website. Check RTC (Real-Time Clock): The device’s RTC might not be properly set. Use the following steps to sync the time: Connect the device to Wi-Fi (if supported) to sync the time automatically. Manually set the RTC using the device’s configuration menu or via a script. Reconfigure V-Training: Reset the V-Training application settings to default and reconfigure it. Ensure the timestamp settings in the app are correctly configured. Verify SD Card: A corrupted or improperly formatted SD card can cause timestamp issues. Format the SD card to FAT32 and try again. Factory Reset: If the issue persists, perform a factory reset on the device and reinstall the firmware and V-Training application.
