CPU Usage: top vs ps

Ben Limpanukorn

Last week I measured the performance impact of sending and receiving messages over a Bluetooth link to see how well it would scale up if needed. The metrics I chose were the percentages of CPU and RAM used by the running process. To collect this data, two common tools came to mind: ps and top....

P2P Messaging with PyBlueZ

Ben Limpanukorn

The PyBlueZ library provides an easy to use interface for communicating over Bluetooth in Python. While Python has native support for Bluetooth with its sockets interface, it is only available for Python v3.3 and up. In addition the PyBlueZ provides a lower-level interface for Bluetooth that can b...
