1. Is there a way to clear the display of the serial data?? At times I want to capture a single packet sequence, but the data gets really muddied up fast.
Yes, just before entering the Sniffer, select the SINGLE mode (see section 3.8 of the manual).
2. Any way to pass the data off to another program for analysis?? Maybe saving it to a file or logging it as it's received?
No logging of data yet. You can use the PC application to observe the same data on the computer as on the device's display.
