Device information

This example shows how you can query device information.The first part of the code queries all available devices without actually booting any device. For each found device, it prints the following information:

Device name: Either IP, in case of OAK PoE cameras, or USB path in case of OAK USB cameras
MxId: Unique Mx (chip) identification code
State: State of the device. Note that OAK PoE cameras have bootloader flashed which initializes the network stack

Afterwards, the example boots into the first found device and prints available camera sensors, and reads calibration and eeprom data which stores product and board names.

3Found device '1.3', MxId: '18443010D116631200', State: 'UNBOOTED'
4Found device '192.168.33.201', MxId: '184430102163DB0F00', State: 'BOOTLOADER'
5Found device '192.168.33.192', MxId: '1844301011F4C51200', State: 'BOOTLOADER'

7Booting the first available camera (1.3)...
8Available camera sensors:  {<CameraBoardSocket.CAM_C: 2>: 'OV9282', <CameraBoardSocket.CAM_A: 0>: 'IMX378', <CameraBoardSocket.CAM_B: 1>: 'OV9282'}
9Product name: OAK-D Pro AF, board name DM9098

This example requires the DepthAI v3 API, see installation instructions.
