## Unreleased
### Added
HCI: `btstack_transport_sco.h` allows to support SCO over physical PCM/I2S interface (`HAVE_SCO_TRANSPORT`)
POSIX: `btstack_transport_sco_i2s_test_bridge.c` implements SCO transport interface for UART-to-I2S test bridge
btstack_uart: `btstack_uart_t` interface extends `btstack_uart_block_t`:

Run Loop Base: functionality used in most platform run loop implementations
- Run Loop Base: functionality used in most platform run loop implementations

events instead of callback, and `RFCOMM_DATA_PACKET` for received data
