.. _ant_release_notes_040: v0.4.0 Release Notes #################### .. contents:: :local: :depth: 2 This release provides EXPERIMENTAL support for developing ANT and ANT+ enabled applications with the Nordic nRF Connect SDK. .. important:: - The release is for evaluation purposes only. It is not intended for product development. - The release is not fully tested and is provided without guarantee of functionality. - The release is not optimized for performance or power consumption. Highlights ********** * Multiprotocol support (ANT and BLE) can be evaluated by enabling the configurations for both protocols. See the :ref:`Integration notes ` for details. * New Samples - ANT Background Scanning (samples/ant_background_scanning) - ANT+ HRM RX (samples/ant_plus/ant_hrm/hrm_rx) - BLE ANT+ HRM Relay (samples/multiprotocol/ble_ant_app_hrm) * New Libraries - ANT Search Config Supported boards **************** * PCA10095 (nRF5340 Development Kit) Limitations *********** * Multiprotocol coexistence with BLE is experimental and has been tested with the provided default sample configuration only (``hci_rpmsg``) * Multiprotocol coexistence with any other wireless radio protocol is untested * The ANT Library (libant.a) is not RTOS-independent for this release due to a Zephyr Kernel dependency Unsupported ANT features include: * Encrypted Channels * PA/LNA Support * Time Sync * Scanning Channel * High Duty Search Channel Changelog ********* * Updated header include paths for compatibility with Zephyr SDK 0.15.x. * Default ANT_TOTAL_CHANNELS_ALLOCATED increased from 8 to 15. * Applied nRF5340 Revision 1 Errata workarounds: - [117] RADIO: Changing MODE requires additional configuration - [158] RADIO: Using POWER register clears RADIO trim values
