Using IAP Firmware Update

warning

If you're using a compatible STM32, ESP32, or nRF microcontroller, we highly recommend using Notecard Outboard Firmware Update to perform DFU operations as it's more reliable, secure, and you can rollback any unintended changes.

IAP (In Application Programming) is a more traditional form of DFU that performs firmware updates while the program is running.
