VMgr_LatencyNotifs
This application was added in REL-1.1.0.
Introduction
This example script subscribes to all data notifications and prints the latency of each packet.
The script connects to a Manager using the Python library and does the following:
- Prompts the user for the VManager IP address
- Subscribes to data notifications
- Prints out MAC address and latency of each data packet received (in milliseconds)
It connects to:
- The SmartMesh IP VManager
Running
You can run the VMgr_LatencyNotifs.py application:
- By double-clicking on its source files at
/vmanager_apps/VMgr_LatencyNotifs.py
