1.7 HCI Trace
In addition to the ability to record Bluetooth traffic off-the-air, using the
analyzer's hardware and radio module, the Merlin can record serial
Bluetooth HCI traffic from Bluetooth devices, or 'IUT's (Implementations
Under Test).
While the off-the-air traffic is 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).
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.
