Script get local IP

This example can only run on OAK POE devices. You need bootloader on/above version 0.0.15. You can flash bootloader by running python3 examples/bootloader/flash_bootloader.py.

This example shows you how to get local IP (IP in the private network) of the device.

Demo

Command Line

1~/depthai-python/examples/Script$ python3 script_get_ip.py

Setup

Please run the install script to download all required dependencies. Please note that this script must be ran from git context, so you have to download the depthai-python repository first and then run the script

Command Line

1git clone https://github.com/luxonis/depthai-python.git
2cd depthai-python/examples
3python3 install_requirements.py
