OTA DFU Without Compromise

on YouTube ↗39m

" summary

Demonstrates an outboard DFU approach where a Blues Wireless note card performs bootloader entry and writes firmware to hosts (STM32, ESP32, nRF52840) so the main MCU needs only a hub.set and card.dfu call. Cooperative DFU required 311 lines of host code and per-chunk CRC, while outboard DFU applies binaries (examples: 282k ESP32, 55k Arduino, 46k Zephyr, 78k CircuitPython binpack) and switches languages/RTOS live; demos complete successfully in beta.
