CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 7.4 Recording Options - Actions The Actions screen allows you to specify the type of action that BTTracer should perform when it encounters the events specified in the Events window. Actions Window Layout The Actions window divides into three sections: a left, a center, and a right section. The left section displays Event buttons such as Header buttons and Error buttons.
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 This center section can also hold Event buttons such as Errors and Payload Hdr1. Event buttons in this section are used to create triggers based on a sequence of Events. Event Sequencing is explained later in the chapter. The right section has three permanent buttons for setting actions. These buttons are Trigger, Filter Out/In, and Restart. These buttons allow you to set actions such as triggering or filtering.
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 The Actions window showing a condition based on a Poll packet and a counter. This condition reads "Trigger after the 21st Poll packet." Connecting Events to Counters To connect an event to a counter, click an Event button, then click one of the two counter buttons. An arrow will appear that will join the Event to the Counter and then to a trigger.
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 The following example reads "Trigger after any combination of 5 Poll packets and FHS packets have occurred." Linking Two Events to Two or More Counters - If an Event is linked to Count1 and a second event is linked to Count2, it creates an "or" statement. This statement reads "Trigger when Count1 OR Count2 has reached their specified values." This example reads "Trigger when Count1 has counted 5 Poll packets or Count2 has counted 10 FHS packets.
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 Counters Blue Dot Menu The Count1 and Count2 blue dot menus allow the value of their counters to be changed. The value you specify here tells BTTracer how many instances of an event must take place before a trigger occurs. The counter can be set between 1 and 65,535. To set a Counter, Step 1 Click on the blue dot in the upper left corner of the Count button.
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 As an example, look at the specifications set in the following screen: Counter 1 has been set to trigger four events after 15 occurrences. But the Counter does not count 15 occurrences for EACH event. It counts ALL events as they happen to occur until it reaches a total of 15 and then triggers. Filter Out/In Blue Dot Menu The Filter Out/In button toggles between "Filter Out" and "Filter In".
CATC BTTracer Protocol Analyzer User’s Manual Version 1.0 Blue Dot Menus for the Event Buttons The Errors button and the first Headers button (marked "Hdr1") have the same Blue Dot menus. These menus allow BTTracer to trigger external output. To enable or disable external trigger output, Step 1 Click the Blue Dot on an Event button such as Hdr1 or Errors.
