SIP/VoIP (PJSIP)

Key Practical Notes for App Development

  1. MQTT: Prefer paho-mqtt (Python) or lua-mosquitto (Lua) over shelling out to mosquitto_pub/sub.

  2. Modbus: pymodbus 3.6.7 is available — no need to implement raw TCP framing.

  3. Serial/RS-485: Use pyserial for serial comms.

  4. Audio: pyalsaaudio for direct ALSA access; python-vlc for higher-level playback; ffmpeg via subprocess for transcoding.

  5. Web API: flask + gunicorn can expose a REST API from within an app.

  6. SQLite: sqlite3 is in both the Python stdlib and as a system binary — safe for local persistent storage.

  7. I2C: Use python3-smbus for I2C bus access (in addition to i2c-tools CLI).

  8. Scheduled tasks: cronie is available — use it for recurring jobs instead of implementing sleep loops where a cron schedule is more appropriate.

  9. Java: openjre-8 is present if a task requires running a .jar file via subprocess.

  10. CGI / lighttpd: haserl enables CGI scripts embedded in HTML served by lighttpd — an alternative to Flask for very lightweight web UIs.

  11. No pip: There is no pip/package manager available to end users. Only the packages listed here are available.
