Part E. Host Controller Interface Functional Specification
vAtlanta r00
This Part describes the functional specification for the Host Controller interface (HCI). The HCI provides a uniform command interface to a Controller.
1. Introduction
This Part of the specification describes the functional specifications for the Host Controller interface (HCI). The HCI provides a uniform command method for the Host to access Controller capabilities and to control connections to other Controllers. For the BR/EDR or LE Controller, these commands typically involve the Link Manager (LM) to exchange LMP commands or the Link Layer (LL) to exchange LL Control packets with remote Bluetooth devices. For details, see [Vol 2] Part C, Link Manager Protocol Specification and [Vol 6] Part B, Link Layer Specification.
The HCI layer spans the boundary between the Host and Controller. As a result, HCI has two roles: the Upper HCI, used by and residing within the Host, and the Lower HCI, used by and residing within the Controller.
The rest of this section provides a brief overview of the lower layers of the Bluetooth software stack and of the Bluetooth hardware. Section 2 provides an overview of the Host Controller Transport Layer. Section 3 lists the HCI commands and events and specifies the support requirements on different types of implementation. Section 4 describes the flow control used between the Host and the Controller. Section 5 describes the various data formats used by HCI. Section 6 further describes certain parameters that are common to several commands. Section 7 describes each of the HCI commands in detail, identifies parameters for each of the commands, and lists events associated with each command.
The specification is applicable to the following types of Controllers:
BR/EDR Controller
BR/EDR/LE Controller
LE Controller
In the following sections, the term “BR/EDR Controller” is used to describe the BR/EDR functionality of a Controller which may be either a BR/EDR only Controller or a BR/EDR/LE Controller. Similarly, the term “LE Controller” is used to describe the LE functionality of a Controller which may be either an LE only Controller or a BR/EDR/LE Controller.
1.1. Lower Layers of the Bluetooth software stack
Figure 1.1 provides an overview of the lower software layers.
Several layers may exist between the Upper HCI and the Lower HCI. These intermediate layers, collectively the "Host Controller Transport Layer", provide the ability to transfer data without intimate knowledge of the data.
Figure 1.2 illustrates the path of a data transfer from one device to another. The Upper HCI on the Host exchanges data and commands with the Lower HCI on the Bluetooth hardware. The Host Controller Transport Layer provides both HCI roles with the ability to exchange information with each other.
The Host will receive asynchronous notifications of HCI events independent of which Host Controller Transport Layer is used. HCI events are used for notifying the Host when something occurs. When the Host discovers that an event has occurred it will then parse the received event packet to determine which event occurred.
A BR/EDR/LE Controller uses one shared command buffer and flow control for BR/EDR and LE. Data buffers can be either shared between BR/EDR and LE or there may be separate data buffers for BR/EDR and LE. The configuration of a Controller is determined through HCI.
1.2. Cross-version issues
The Host and Controller communicating through HCI are not required to support the same version of this specification (see [Vol 0] Part D, Section 4).
If the Controller conforms to a newer version of the specification than the Host, events (including HCI_Command_Status and HCI_Command_Complete) may include values that are reserved for future use in the version supported by the Host. In the case of the Status parameter of the HCI_Command_Status and HCI_Command_Complete events, a value that is reserved for future use must be treated as if it were the error code Unspecified Error (0x1F) (see [Vol 1] Part F, Section 1.3). In all other circumstances the Host must obey the requirements for devices receiving reserved values (see [Vol 1] Part E, Section 2.4).
Note
Note: If the Host conforms to a newer version of the specification than the Controller and uses a command feature that is not part of the older specification version, then the Controller will report an error. Failure to handle such errors could result in unexpected behavior.
2. Overview of Host Controller transport layer
The Host driver stack has a transport layer between the Host Controller Interface driver and the Host.
The main goal of this transport layer is transparency. The Host Controller Interface driver (which interfaces to the Controller) should be independent of the underlying transport technology. In addition, the transport should not require any understanding of the data that the Host Controller Interface driver passes to the Controller. This allows the logical interface (HCI) or the Controller to be upgraded without affecting the transport layer.
The specified Host Controller Transport Layers are described in the other parts of Volume 4.

3. Overview of commands and events
The commands and events are sent between the Host and the Controller.
Table 3.1 lists each HCI command and event together with specification version information, a summary description, and the support requirements.
A command or event may have more than one version. All versions of a command or event implement the same basic functionality but with detail differences, such as additional parameters relating to newer features. The different versions are indicated by "[v1]", etc. where necessary; if no version number is given, a reference to the command or event applies to all versions.
The specification version information gives the version number of the specification which first specified this command or event or, where more than one specification version number is shown, each version of this command or event.
Table 3.1 lists the requirements for a Controller to support each command or event or version thereof. Subject to Section 3.2, a Controller shall support the command or event if it is shown as mandatory for at least one of the transports (i.e., BR/EDR or LE) that the Controller supports, otherwise the Controller may support the command or event if it is shown as optional for at least one of the transports that the Controller supports, otherwise it shall not support the command or event. If the command or event has more than one version, then this determination is made for each version separately using the requirements listed in the table for that version. The LMP features mentioned in the conditions are defined in [Vol 2] Part C, Section 3.2 and the Link Layer features in [Vol 6] Part B, Section 4.6.
