tinyble

A BLE peripheral host for Matter commissioning. It replaces Zephyr's Bluetooth host and drives the controller, Zephyr's or Nordic's, unchanged through raw HCI. Portable C11.

6.7 KB flash, 2.5 KB RAM, LTO release build.

Why it is small

• One 251 B buffer each way. Nothing is queued.
• One const GATT table, 4 B per attribute.
• Link-time hooks. No threads, no locks.
• Eight HCI commands.

Use

CONFIG_BT_HCI_RAW=y
CONFIG_TINYBLE=y
CONFIG_TINYBLE_TINYTALK=y    # tinytalk's matter_ble.h on tinyble
CONFIG_TINYTALK_BLE=n
CONFIG_TINYBLE_TINYFOTA=y    # optional: tinyfota's DFU services

Optional ATT behaviour: the TB_* macros in include/tinyble/tinyble.h.

Test

make test                    # host, against a fake controller
make asan
make size ARM_CC=<arm-gcc>   # gate: 5.2 KB flash, 0.7 KB RAM
