9. Reading a CATC Trace
9.1 Trace View Features
The BTTracer packet view display makes extensive use of color and graphics
to fully document the captured traffic.
Packets are shown on separate rows, with their individual fields both labeled
and color coded.
Packets are numbered (sequentially, as recorded), time-stamped, and
highlighted to show the device status (master or slave).
Display formats can be named and saved for later use.
Pop-up Tool Tips annotate packet fields with detailed information about their
contents.
Data fields can be collapsed to occupy minimal space in the display (which can
in turn be zoomed in and out to optimize screen utilization).
The display software can operate independent of the hardware and so can
function as a stand-alone Trace Viewer that may be freely distributed.

Packet #0 is described from left to right:
