### 9.3 Patches
### 9.3 Platform Notes
- **nRF52840**: Zephyr open-source BLE controller, UF2 bootloader, partial flash erase for BLE coexistence
- **nRF54L15**: Same BLE controller as nRF52, CMSIS-DAP via SAMD11 bridge, no native USB
- **ESP32**: Espressif proprietary BLE blob, 32KB heap, asserts disabled (blob IRQ false positives)
- **EFR32MG24**: SiLabs proprietary BLE blob, 32KB heap, SEMAILBOX enabled for hardware TRNG/crypto entropy, ADC disabled (no battery divider), CMSIS-DAP via onboard SAMD11
