The PSoC 4 SoCs can be programmed with the "BLE DTM" HCI Firmware from the PSoC Creator Kit Examples. The UART baudrate is set to 115200. For higher baud rates, the clocks probably need to be configured differently, as the IDE gives a warning about this.
The CYW20819 can be used as a SoC with Cypress' Bluetooth stack. To use it as a regular Bluetooth Controller over HCI H4, CTS must be asserted during Power-Up / Reset.
**Init scripts**: For UART connected chipsets, an init script has to be uploaded after power on. For Bluetooth chipsets that are used in Broadcom Wifi+Bluetooth combos, this file often can be found as a binary file in Linux distributions with the ending *'.hcd'* or as part of the WICED SDK as C source file that contains the init script as a data array for use without a file system.
To find the correct file, Broadcom chipsets return their model number when asked for their local name.
