Python, Raspberry Pi and Jetson

:::note Status, checked 2026-11-13 The Python package erdi-lrf (PyPI, MIT) and the Raspberry Pi tools have software tests using a virtual serial port and golden frames from the datasheets. They are Untested against hardware on the compatibility page. The only real-module evidence is the factory capture of LRF22VB and LRF50H made with the vendor tool, see units and out-of-range. :::

erdi-lrf​

pip install erdi-lrf
erdi-lrf models
erdi-lrf --port /dev/ttyUSB0 --model LRF22VB stream --count 20
from erdi_lrf import ErdiLRF

with ErdiLRF("/dev/ttyUSB0", "LRF3000A1") as lrf:
    print(lrf.measure().metres)

Pass the exact model name. The unit, frame format and default baud rate come from it.

Raspberry Pi tools​

erdi-lrf-raspberry-pi-python adds a serial reader, a CSV logger, an MQTT publisher and a MAVLink bridge:

pip install "git+https://github.com/ErdiTech/erdi-lrf-raspberry-pi-python"
erdi-lrf-log  --port /dev/serial0 --model LRF22VB --csv log.csv --decimate 20
erdi-lrf-mqtt --port /dev/serial0 --model LRF100H --host 192.168.1.10 --topic erdi_lrf/distance

Use /dev/serial0 for the Raspberry Pi header UART after enabling it, or /dev/ttyUSB0 for a USB-TTL adapter. The same code runs on a Jetson or any Linux board with a serial port. The MAVLink bridge is described on the PX4 page.
