; BalDav BLE barometer - ESP32-C3 SuperMini + BMP280
; Build & flash over USB, no Arduino IDE:
;   pip install platformio        (once)
;   pio run -t upload             (compile + flash via USB-C)
;   pio device monitor            (optional: see logs)
; ESP32-C3 flashes over its native USB. If upload can't find the port the first time:
; hold BOOT (GPIO9), tap RESET, release BOOT -> it enters download mode, then retry upload.
