  • How to assign static IPs to POE devices

Hi erik,

Ah wish I saw this sooner. This method setStaticIPv4(std::string ip, std::string mask, std::string gateway) is exactly what I was looking for: https://docs.luxonis.com/projects/api/en/latest/references/python/?highlight=.readConfigData()#depthai.DeviceBootloader.Config.setStaticIPv4.

But now I'm a bit afraid the steps I've described thus far may have soft-bricked the device. Is there a way to reset the OAK-1 POE? I do see a Module Reset Button labelled G here although I'm not sure if it is relevant: "https://docs.luxonis.com/projects/hardware/en/latest/pages/SJ2096POE.html"

      Hi erik , Running fix_softbrick.py in the linked announcement worked! Now I can connect to my device.

      I will wait for an example on how to use the bootloader API for (.setStaticIPv4(ipv4, mask, gateway), .setDynamicIPv4(ipv4, mask, gateway)).

      I wrote a script to use the bootloader API which shows that the .getIPv4(), .getIPv4Mask(), .getIPv4Gateway(), .isStaticIPV4() are set, but when I rerun the same script I do not see the changes to the bootloader just made.

      # usr/bin/env/python3

import depthai as dai

current_ip = input("Enter IP of POE OAK Device: ").strip() # example: 172.16.15.17
found_poe, poe = dai.DeviceBase.getDeviceByMxId(current_ip)

if not found_poe:
    print(f"Did not find {current_ip}, exiting.")
    exit(1)

print(f"Found {current_ip}")
poebl = dai.DeviceBootloader(poe)
device_config = poebl.Config()

def see_config():
	print("\nCurrent IPv4 Configurations: ")
	print(f"IPv4:           {device_config.getIPv4()}")
	print(f"IPv4 Mask:      {device_config.getIPv4Mask()}") 
	print(f"IPv4 Gateway:   {device_config.getIPv4Gateway()}")
	print(f"Is IPv4 static: {device_config.isStaticIPV4()}")

def enter_new_config():
	print("\nNew IPv4 Configurations: ")
	ipv4 = input("Enter IPv4: ").strip()
	mask = input("Enter IPv4 Mask: ").strip()
	gateway = input("Enter IPv4 Gateway: ").strip()
	is_static = True if input("Is this a static IPv4 (sets dynamic IPv4 if no)? (y/n): ").strip() == "y" else False

	return ipv4, mask, gateway, is_static

def confirm_new_config(ipv4, mask, gateway, is_static):
	print("\nEntered IPv4 Configurations: ")
	print(f"New IPv4:           {ipv4}")
	print(f"New IPv4 Mask:      {mask}") 
	print(f"New IPv4 Gateway:   {gateway}")
	print(f"Is New IPv4 static: {is_static}")

	if is_static:
		print("Note: Static IPv4 will not start DHCP client")
	else:
		print("Note: Dynamic IPv4 will be used (sets IP and starts DHCP client)")

	is_confirmed = True if input("\nPlease confirm this Configuration to Set (y/n): ").strip() == "y" else False

	if not is_confirmed:
		print("New Config is not Confirmed, exiting.")
		exit(1)

def perform_config(ipv4, mask, gateway, is_static):
	print("Setting New Configurations...")
 	
	if is_static:
 		device_config.setStaticIPv4(ipv4, mask, gateway)
	else:
		device_config.setDynamicIPv4(ipv4, mask, gateway)
	
	print("Configuration Complete")

def run_config():
    see_config()
    ipv4, mask, gateway, is_static = enter_new_config()
    confirm_new_config(ipv4, mask, gateway, is_static)
    perform_config(ipv4, mask, gateway, is_static)
    see_config()

if __name__ == "__main__":
	run_config()
          5 days later

          erik any idea when an example will be added. I'm a newbie on these cameras and any help is appreciated.

            gbanuru I was able to run your script, but I'm not seeing the updates when I rerun your script.

              Hi gbanuru
              Sorry for delay on this.

              To read out config from device do the following:

              device_config = poebl.readConfig()

              Your current code just creates a new empty dai.DeviceBootloader.Config object.

              To flash the config run the following at the end (just editing the dai.DeviceBootloader.Config object will not "save" the configuration)

              poebl.flashConfig(device_config)

              Regards, Martin

                I just tried the code below and it correctly sets a static IP, which it keeps even after a power reset. Could you try it out? Thanks!

                import depthai as dai

(found, info) = dai.DeviceBootloader.getFirstAvailableDevice()

def check_str(s: str):
    spl = s.split(".")
    if len(spl) != 4:
        raise ValueError(f"Entered value {s} doesn't contain 3 dots. Value has to be in the following format: '255.255.255.255'")
    for num in spl:
        if 255 < int(num):
            raise ValueError("Entered values can't be above 255!")
    return s

if found:
    print(f'Found device with name: {info.desc.name}');
    with dai.DeviceBootloader(info) as bl:
        conf = dai.DeviceBootloader.Config()

        ipv4 = check_str(input("Enter IPv4: ").strip())
        mask = check_str(input("Enter IPv4 Mask: ").strip())
        gateway = check_str(input("Enter IPv4 Gateway: ").strip())

        val = input(f"Flashing static IPv4 {ipv4}, mask {mask}, gateway {gateway} to the POE device. Enter 'y' to confirm. ").strip()
        if val != 'y':
            raise Exception("Flashing aborted.")

        conf.setStaticIPv4(ipv4, mask, gateway)
        (success, error) = bl.flashConfig(conf)

        if not success:
            print(f"Error occured while flashing the boot config: {error}")
        else:
            print(f"Boot config flashed successfully")

                  erik , I'm getting the following error:

                  AttributeError: type object 'depthai.DeviceBootloader' has no attribute 'Config

                  • erik replied to this.

                      Cmitchell63 Please update the library to the latest version, python3 -mpip install depthai -U
                      Thanks, Erik

                          erik done -- the script runs, showing " Boot config flashed successfully", although the script just hangs after that.
