| 1In this chapter, we first explain how Bluetooth chipsets are connected physically and then provide information about popular Bluetooth chipset and their use with BTstack. 2 3## HCI Interface 4 5The communication between a Host (a computer or an MCU) and a Host Controller (the actual Bluetooth chipset) follows the Host Controller Interface (HCI), see {@fig:HostChipsetConnection}. HCI defines how commands, events, asynchronous and synchronous data packets are exchanged. Asynchronous packets (ACL) are used for data transfer, while synchronous packets (SCO) are used for Voice with the Headset and the Hands-Free Profiles. 6 7{#fig:HostChipsetConnection} 8 --- 54 unchanged lines hidden (view full) --- 63Cypress CYW43xxx | Dual mode + Wifi | H4, H5 | Don't know | Partially (2) | Don't know | No | Don't know | Don't know | bcm | Bluetooth + Wifi Combo Controller 64Cypress PSoC 4 | LE | H4 | Don't know | n.a. | Yes | Don't know | n.a. | Don't know | | HCI Firmware part of PSoC Creator kits examples 65Dialog DA14581 | LE | H4, SPI | No | n.a. | No | No | n.a. | Don't know | da14581 | Official HCI firmware included in BTstack 66Dialog DA14585 | LE | H4, SPI | No | n.a. | Yes | Yes | n.a. | Yes | da14581 | Official HCI firmware included in BTstack 67Dialog DA1469x | LE | H4, SPI | No | n.a. | Yes | Yes | n.a. | Yes | da14581 | HCI Firmware part of DA1469x SDK 68Espressif ESP32 | Dual mode + Wifi | VHCI | Yes | Not yet | Yes | Yes | Yes | Don't know | | SoC with Bluetooth and Wifi 69EM 9301 | LE | SPI, H4 | No | n.a. | No | No | n.a. | Don't know | em9301 | Custom HCI SPI implementation 70EM 9304 | LE | SPI, H4 | Yes | n.a. | Yes | Yes | n.a. | Don't know | em9301 | Custom HCI SPI implementation | 1In this chapter, we first explain how Bluetooth chipsets are connected physically and then provide information about popular Bluetooth chipset and their use with BTstack. 2 3## HCI Interface 4 5The communication between a Host (a computer or an MCU) and a Host Controller (the actual Bluetooth chipset) follows the Host Controller Interface (HCI), see {@fig:HostChipsetConnection}.
