| 1# 2 3In this chapter, we first explain how Bluetooth chipsets are connected physically and then provide information about popular Bluetooth chipset and their use with BTstack. 4 5## HCI Interface 6 7The 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. 8 --- 69 unchanged lines hidden (view full) --- 78| Espressif ESP32-S3,C3 | LE + Wifi | VHCI, H4 | Yes | No | Yes | Yes | Yes | Yes | | SoC with Bluetooth and Wifi | 79| EM 9301 | LE | SPI, H4 | No | n.a. | No | No | n.a. | Don't know | em9301 | Custom HCI SPI implementation | 80| EM 9304 | LE | SPI, H4 | Yes | n.a. | Yes | Yes | n.a. | Don't know | em9301 | Custom HCI SPI implementation | 81| EM 9305 | LE | SPI, H4 | Yes | n.a. | Yes | Yes | n.a. | Yes | em9301 | Custom HCI SPI implementation | 82| Intel Dual Wireless 3165, 8260, 8265 | Dual mode | USB | Yes | Probably | Don't know | Don't know | Don't know | Don't know | intel | Firmware size: 400 kB | 83| Nordic nRF | LE | H4 | Fixed Random | n.a. | Yes | Yes | n.a. | Yes | | Requires HCI firmware | 84| NXP 88W8997 | Dual mode | H4 | Yes | Partially(2) | Yes | Yes | No | Yes | nxp | Requires initial firmware | 85| NXP IW416 | Dual mode | H4 | Yes | No | Yes | Yes | No | Yes | nxp | Requires initial firmware | | 1# 2 3In this chapter, we first explain how Bluetooth chipsets are connected physically and then provide information about popular Bluetooth chipset and their use with BTstack. 4 5## HCI Interface 6 7The 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}.
