Integrated BLE Controller (CMAC) requires a binary firmware to be loaded. Such firmware is distributed by Dialog Semiconductor in SDK package which has to be obtained separately, see: https://www.dialog-semiconductor.com/products/da1469x-product-family Firmware is available as part of following library in SDK package: sdk/interfaces/ble/binaries/DA1469x-Release/libble_stack_da1469x.a By default, CMAC driver will look for this file in its package root directory (i.e. nimble/transport/da1469x/cmac_driver) but this can be changed using CMAC_IMAGE_FILE_NAME syscfg variable. Current version of CMAC driver was tested with SDK version 10.0.4.66.
