Firmware v6.1.1 for BlueSaab hardware v6.x (STM32F103RB + RN52) — the last RN52-era firmware, rebuilt reproducibly from the tagged 2019 source. Byte-identical source to the original v6.1.1 release on upstream.

  • Toolchain: ARM GCC 8.5.0 (arm-none-eabi-gcc@8), plain make
  • Footprint: 103 KB flash / ~10 KB static RAM
  • SHA-256 BlueSaab-v6.1.1.bin: a2db3f28523361e8edad3c31bde47c4e18a64b196fdc0c5467a842838910dee2
  • SHA-256 BlueSaab-v6.1.1.hex: 20c1d8a5cd10ad9845b998bf8520f3cc2a26d340e7824345117410a83ee91a68

Flashing: see docs/FLASHING_v6_HOWTO.md (revival branch) — primary method is the ROM serial bootloader (FTDI header + BOOT0): back up first with stm32flash -r, then stm32flash -w BlueSaab-v6.1.1.bin -v <port>.

Usage & pairing: docs/USAGE_v6.md (preset 1 = pair a new phone).
