Script get local IP

Note

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

~/depthai-python/examples/Script$ python3 script_get_ip.py
Found device with name: 14442C1031425FD700-ma2480
Version: 0.0.15

Names of layers: ['fp16', 'uint8']
NNData size: 13
FP16 values: [1.0, 1.2001953125, 3.900390625, 5.5]
UINT8 values: [6, 9, 4, 2, 0]
