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.
The CYW43xxx series contains a Wifi and Bluetooth Controller. The Bluetooth Controller can be used independent from the Wifi part.
**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.

## Espressif ESP32
The ESP32 is a SoC with a built-in Dual mode Bluetooth and Wifi radio. The HCI Controller is implemented in software and accessed via a so called Virtual HCI (VHCI) interface. It supports both LE Data Length Extensions (DLE) as well as multiple LE roles. SCO isn't supported currently, but [Espressif is working on it](https://github.com/espressif/esp-idf/issues/1118).
## EM Microelectronic Marin
For a long time, the EM9301 has been the only Bluetooth Single-Mode LE chipset with an HCI interface. The EM9301 can be connected via SPI or UART. The UART interface does not support hardware flow control and is not recommended for use with BTstack. The SPI mode uses a proprietary but documented extension to implement flow control and signal if the EM9301 has data to send.

**BTstack integration**: The common code for the EM9304 is provided by *btstack_chipset_em9301.c*. During the setup, *btstack_chipset_em9301_instance* function is used to get a *btstack_chipset_t* instance and passed to *hci_init* function. It enables to set the BD Addr during start.

Wifi/Bluetooth combo cards mainly used in mobile computers. The Bluetooth part requires the upload of a firmware file and a configuration file. SCO, DLE, Multiple roles not tested.
## Nordic nRF5 series
The Single-Mode LE chipsets from the Nordic nRF5 series chipsets usually do not have an HCI interface. Instead, they provide an LE Bluetooth Stack as a binary library, the so-called *SoftDevices*. Developer can write their Bluetooth application on top of this library. Since the chipset can be programmed, it can also be loaded with a firmware that provides a regular HCI H4 interface for a Host.

## Texas Instruments CC256x series
The Texas Instruments CC256x series is currently in its fourth iteration and provides a Classic-only (CC2560), a Dual-mode (CC2564), and a Classic + ANT (CC2567) model. A variant of the Dual-mode chipset is also integrated into TI's WiLink 8 Wifi+Bluetooth combo modules of the WL183x, WL185x, WL187x, and WL189x series. Some of the latter support ANT as well.
