1*34fd36daSMatthias Ringwald# BTstack Port with Cinnamon for Nordic nRF5 Series 20138fcaeSMatthias Ringwald 30138fcaeSMatthias Ringwald*Cinnamon* is BlueKitchen's minimal, yet robust Controller/Link Layer implementation for use with BTstack. 40138fcaeSMatthias Ringwald 50138fcaeSMatthias RingwaldIn contrast to common Link Layer implementations, our focus is on a robust and compact implementation for production use, 60138fcaeSMatthias Ringwaldwhere code size matters (e.g. current code size about 8 kB). 70138fcaeSMatthias Ringwald 80138fcaeSMatthias Ringwald## Status 90138fcaeSMatthias RingwaldThe current implementation supports a single Peripheral role, or, passive scanning in Observer role. In the Peripheral role, 100138fcaeSMatthias Ringwaldchannel map updates, as well as connection param updates are supported. 110138fcaeSMatthias Ringwald 120138fcaeSMatthias RingwaldSupport for LE Central Role as well as Encryption is planned but not supported yet. 130138fcaeSMatthias Ringwald 140138fcaeSMatthias Ringwald## Requirements 150138fcaeSMatthias Ringwald- arm-none-eabi toolchain 160138fcaeSMatthias Ringwald- Nordic's nRF5-SDK 170138fcaeSMatthias Ringwald 180138fcaeSMatthias Ringwald## Supported Hardware 190138fcaeSMatthias RingwaldAll nNRF5x SOCs. Built files are provided for PCA10040 (52832 DK), but others can be supported with minimal changes. 200138fcaeSMatthias Ringwald 210138fcaeSMatthias Ringwald## Use 220138fcaeSMatthias Ringwald- Provide path to nRF5-SDK either in `NRF5_SDK_ROOT` environment variable or directly in `pca10040/armgcc/Makefile`. 230138fcaeSMatthias Ringwald- run make 240138fcaeSMatthias Ringwald- All supported examples are built in the `build` folder. 250138fcaeSMatthias Ringwald- You can use Segger's OZONE with the provided `EXAMPLE.jdebug` project file to flash and run the examples. 26
