@konacurrents Agree with you! USB uploads can be frustrating when they hiccup or stop halfway. Using OTA to update by exporting the binary and then pushing it through the cloud just makes things way smoother. It’s cool that you can even trigger the update from the serial monitor or send MQTT messages to update devices remotely. That way, managing multiple M5 units becomes much easier and less stressful. OTA feels like the better, more reliable way to go. Thanks for sharing your experience.
