The USB Transport Layer has been specified by the Bluetooth
SIG (Part H:2), and allows HCI level com-
munication between a host controller (STLC2415) and a host (e.g. PC), via a USB interface. The USB
Transport Layer is completely implemented in SW. It accepts HCI messages from the HCI Layer, prepares
it for transmission over a USB bus, and sends it to the USB Driver. It reassembles the HCI messages from
USB data received from the USB Driver, and sends these messages to the HCI Layer. The Transport Lay-
er does not interprete the contents (payload) of the HCI messages; it only examines the header.
HCI USB TRANSPORT LAYER
10 POWER CLASS1 SUPPORT
The chip can control an external power amplifier (PA). Several signals are duplicated on GPIOs for this
purpose in order to avoid digital/analog noise loops in the radio.
The Class1_En register enables the alternate functions of GPIO[15:6] to generate the signals for driving
an external PA in a Bluetooth
power class1 application.
Every bit enables a dedicated signal on a GPIO pin, as described in table 12.
Table 12. Power Class 1 Functionality
rx_on is the same as the rx_on output pin. Not rx_on is the inverted signal, in order to save components
on the application board.
PA7 to PA0 are the power amplifier control lines. They are managed, on a connection basis, by the base-
band core. The Power Level programmed for a certain Bluetooth
connection is manged by the firmware,
as specified in the Bluetooth
SIG spec.
