APIs and drivers to access on board peripherals.
Bluetooth® protocols include GAP, GATT, SMP, HID.
LE profile APIs, libraries, and sample apps.
Support for Over-The-Air (OTA) upgrade.
Device Configurator for creating custom pin mapping.
Bluetooth® Configurator for creating LE GATT Database.
Documentation for APIs, datasheet, profiles, and features.

Kits Supported

CYW943022BTEVK-01

106 ball WLBGA package, Audio Arduino shield with on-board microphones, audio codec chip, headphone output, expansion header (J5) for direct access to BT_GPIO, i2S, UART, user switches and LEDs, and a USB connector for power, programming, and USB-UART bridge. Max UART baud rate is 3M

Downloading application to the kit

This kit does not have SFLASH, so image download and write to FLASH is not possible as with other AIROC™ boards. Instead, the DIRECT_LOAD feature is the default/only option for downloading new application FW. The application 'make build' target will produce a .hcd image file, and the application 'make program' target can be used to download to RAM on the device and instruct the device to reboot directly from RAM instead of the read-only ROM boot image.

If you have issues downloading to the kit, power cycle the kit to boot from the ROM image.
