| # WiFi Host Driver Board Support Package Integration Release Notes | |
| This library helps streamline the process of getting the WiFi Host Driver (WHD) setup and running with a Board Support Package (BSP) that includes a WLAN chip. | |
| ### What's Included? | |
| * APIs for setting up the WHD interface with the BSP's SDIO interface. | |
| * APIs for connecting WHD to LwIP/NetXDuo memory buffers (whd_buffer_funcs_t) | |
| * Framework for connecting WHD to LwIP/NetXDuo network interface (whd_netif_funcs_t) | |
| ### What Changed? | |
| #### v2.3.0 | |
| * Added support for CAT5. | |
| * Added support for IOCTL buffers greater than max MTU for CAT5. | |
| #### v2.2.1 | |
| * Allow BSP to override default configuration of WL_REG_ON and WL_HOST_WAKE pins. | |
| #### v2.2.0 | |
| * Fixed issue where some 3.0-style BSPs were inappropriately using SDIO interface. | |
| #### v2.1.0 | |
| * Added support for dyanmically allocated NetX Duo packets to support WHD IOVARs with payloads larger than MTU. | |
| * Added support for NetX Duo | |
| * Made SDIO initialization more robust | |
| #### v2.0.0 | |
| * Added support for different communication protocols (SDIO, SPI, DMA) between MCU and Radio | |
| * Card initialization process improvements. Code now checks whether SDIO device supports 1.8V signaling, and, if it does, performs the actions needed in order to switch to 1.8V. | |
| * Added support for overriding the default country code by defining CY_WIFI_COUNTRY to a value from whd_country_code_t. | |
| * Added argument to cybsp_wifi_init_primary_extended() to set WHD initialization parameters | |
| * SDIO frequency is increased to 50 MHz if High Speed Mode is supported | |
| * Added support for HAL API v1 or v2 | |
| * Minimum required `wifi-host-driver` library version for this release - `2.0.0` | |
| #### v1.2.0 | |
| * Fixed possible memory corruption issue introduced with changes from v1.1.0 | |
| #### v1.1.2 | |
| * Robustness update for WLAN initialization | |
| #### v1.1.1 | |
| * Update network buffer allocation for improved performance | |
| #### v1.1.0 | |
| * Fixed a memory leak when shutting down the WHD interface | |
| * Minor code style cleanups | |
| #### v1.0.2 | |
| * Minor update for documentation & branding | |
| #### v1.0.1 | |
| * Fixed issue with a missing ; | |
| #### v1.0.0 | |
| * Initial release | |
