6.6 Recording Options - HCI
The HCI property page lets you include HCI traffic from IUTs into the trace.
HCI traffic consists of commands and other traffic that are sent by the IUT
to generate Bluetooth traffic. By default, this option is disabled - meaning
that HCI traffic is not shown in the trace.
HCI Traffic from the IUTs is captured by the analyzer application using an
HCI probe (provided by CATC) that is connected directly to the IUT
hardware. In a typical setup, the HCI commands and data to transmit are
passed from the Bluetooth application to the Bluetooth baseband (Host to
Controller), while events and data that was received are passed from the
Bluetooth baseband to the Bluetooth application (Controller to Host).
To capture the data, the HCI Probe should be connected to the respective
'Host to Controller' and 'Controller to Host' lines. When the recording of the
IUT's HCI is enabled and the application starts a recording, the serial data is
captured as incoming serial data. For this, up to two COM ports should be
configured for each IUT.
HCI Window Layout
The HCI page displays a Debug checkbox, a Configurations List that is
made up of IUTs that were added via the Add button, and buttons labeled
Add, Edit, and Delete.
