Overview of OpenWeave nRF52840 Adaption
The following is a quick overview of the nRF5 adaptation of OpenWeave. Most of this code will have parallels in any new adaptation.
(All file names are relative to openweave-core/src/adaptations/device-layer/...
).
include/Weave/DeviceLayer/nRF5/PlatformManagerImpl.h
nRF5/PlatformManagerImpl.cpp
- Concrete implementation of PlatformManager interface
- Provides initialization of the OpenWeave stack and core event loop for the Weave task
- Relies on GenericPlatformManagerImpl_FreeRTOS<> class to provide most of the implementation
include/Weave/DeviceLayer/nRF5/ConfigurationManagerImpl.h
nRF5/ConfigurationManagerImpl.cpp
- Concrete implementation of ConfigurationManager interface
- Manages storage and retrieval of persistent configuration data
- Relies on GenericConfigurationManagerImpl<> classes to implement most API functionality
- Delegates low-level reading and writing of persistent values to NRF5Config class
include/Weave/DeviceLayer/nRF5/ConnectivityManagerImpl.h
nRF5/ConnectivityManagerImpl.cpp
- Concrete implementation of ConnectivityManager interface
- Provides high-level APIs for managing device connectivity
- Relies on various generic implementation classes to provide API functionality
- Very much a work-in-progress in the nrf52840 branch
include/Weave/DeviceLayer/nRF5/ThreadStackManagerImpl.h
nRF5/ThreadStackManagerImpl.cpp
- Concrete implementation of ThreadStackManager interface
- Supports Thread stack initialization and core event loop processing
- Relies on GenericThreadStackManagerImpl_OpenThread/FreeRTOS/LwIP<> classes to implement most API functionaltiy
- Work-in-progress [2019/04/01]
include/Weave/DeviceLayer/nRF5/BLEManagerImpl.h
nRF5/BLEManagerImpl.cpp
- Concrete implementation of the BLEManager interface
- Maps OpenWeave‘s BLE interface abstractions (BleLayer, BlePlatformDelegate, BleApplicationDelegate) onto the platform’s native BLE services
- Implements Weave-compatible BLE advertising.
nRF5/AESBlockCipher.cpp
- Implements AES block operations
nRF5/Entropy.cpp
- Implements interface to platform entropy source
nRF5/Logging.cpp
- Adaption of Weave debug logging to platform logging facility.
nRF5/NRF5Config.cpp
- Implements low-level read/write of persistent configuration values
- Class API specifically designed to work in conjunction with the GenericConfigurationManagerImpl<> class.
