QXDM Professional: real-time UE logging, filter configuration, message view

What is QXDM?

QXDM (Qualcomm eXtensible Diagnostic Monitor) is the primary tool for capturing real-time protocol logs from Qualcomm-based UEs. It communicates with the modem via the DIAG interface over USB, capturing NAS, RRC, and lower-layer messages as they happen.
