6.6 Recording Options - HCI

The HCI property page lets you include/exclude HCI traffic from the

BTTrainer or Implementations Under Test (IUTs) into the trace. HCI traffic

consists of commands and data that are sent from the host to the controller

and events and data sent from the host to the controller. By default, this

option is disabled - meaning that HCI traffic is not shown in the trace.

These settings are relevant only for BTTrainer mode, where the BTTracer

is monitoring the BTTrainer. The Internal HCI traffic of BTTrainer can also

be recorded.

HCI Trace

Using the analyzer's hardware and radio module, the BTTracer can record

serial Bluetooth HCI traffic from Bluetooth devices, or "IUTs"

(Implementations under test).

While the off-the-air traffic and HCI traffic from BTTrainer™ (if active) are

captured by the analyzers hardware, the 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).
