Commanding and Telemetry Server

Objective

Building a simple commanding and telemetry server using C++20, TCP, and Python (pytest).

Server:

• Written in C++20
• Using TCP sockets (Linux C socket API) to communicate with the client
• Multithreaded:
  • Commanding thread: listen for packets, deserialize packet into op-code (identifying code of the command, as defined by the command definition file) and payload (arguments of the command)
  • Commanding execution threads: run the corresponding function to the command on a separate thread
    • For now, the commands will be modifying the state of the "spacecraft", which will be a thread-safe key-value store (an std::unordered_map with a mutex, for now)
  • Telemetry thread: periodically send the data points from the state of the "spacecraft" over the TCP connection to the client

Client:

• Written in Python
• Connect to telemetry and commanding sockets
• Can manually send commands and read telemetry
• Use Pytest to run an automated test suite
