QUESTION
I am trying to create IoT devices on the Google Cloud through a Python script.
I have set up the project, IoT registry and authenticated my GCloud and linked the GOOGLE_APPLICATION_CREDENTIALS to the json from the corresponding service account.
Why I use the command line to create an account, e.g.
gcloud iot devices create dev01 --project=... --region=... --registry=...
,
it works.
However, my Python script (run through command prompt) does not seem to yield the same results. I used https://cloud.google.com/iot/docs/samples/device-manager-samples#iot-core-create-rs256-python for the iot_v1 reference.
ANSWER
Answered 2020-Oct-28 at 07:17Make sure that the service account being used to create the client has at least the roles/cloudiot.provisioner
Role assigned (if you keep getting the permission errors try adding the roles/cloudiot.admin
role to the service account, as it should grant full control of all IoT devices, find more information about all the available permissions here.)
Once you are sure that the service account has the correct permissions you can take advantage of the the credentials
parameter offered by the iot_v1.DeviceManagerClient() class to make sure you point to the service account key file as explained on the Authentication section of the docs.
QUESTION
I'm having trouble synchronizing data from an observable in a service with a component that consumes the data. The data service calls an api service when it is created to build a list of devices it gets from a server. This appears to be working fine as the device list is built in the data service.
...ANSWER
Answered 2020-Feb-02 at 07:33I am not a 100% sure, but I believe the reason it is not working is that your observable needs to be subscribed to before you pass the data to it. In your code you first pass the data with observer.next(this.devices), then you subscribe. By the time you subscribe the data has already been sent and the event is already finished.
There is a couple of ways this could be solved, one is with a BehaviorSubject.
At the top of your service you add the property
devices$ = new BehaviourSubject([]);
.At the end of your method 'buildDeviceTable()' you add the line
this.devices$.next(this.devices);
.In your component you replace the
this.deviceManager.getDevices().subscribe(
withthis.deviceManager.devices$.subscribe(

I'm trying to do what I thought was simple but have run into a problem I can't solve.
I have a table of strings that is populated from a backend service, and the number of strings can increase over time. So I have a service that populates an array with the strings and returns it as an observable. The service is shown here:

I am trying to implement nativescript-dev-appium in an existing nativescript-angular project and am having a lot of trouble getting the plugin configured.
The simulator appears to be found but the run fails in the before all

QUESTION
I am trying to set up NetBeans 8.0 for development in Java ME (I know this is legacy software, but it is the only software I know of that supports Java ME), however, NetBeans will not detect my Java ME platform in the platform manager any time I try to load it. You can view this error here. My version of Java is 1.8.0_201. The log from the Java ME SDK reads:

I've tried many answers to this on many forums including this one, but none of them have worked. Any help is appreciated.
...ANSWER
Answered 2019-Feb-17 at 01:05Your problem is not trivial to fix, and this is not a solution - it is more of an update for your problem since it is is too large for a comment:
First note that the cause of the failure to add Java ME as a platform within NetBeans is shown in the stack trace: java.net.BindException: Address already in use: JVM_Bind
.
Oracle mention the possibility of getting this exception in many places in their Java ME documentation. For example:
7.2.1 Troubleshooting Device Connection Issues
If the IP address of a device with a running Java ME Embedded runtime instance is not available in the corresponding drop-down list when adding a device connection, see the Device Manager log file. It is located under logs in the Oracle Java ME SDK configuration directory.
The Device Connection log file (device-manager.log) contains errors, warnings, and informational events that you can review in order to find the cause of the problem. The following are some of the common messages that you may encounter:
WARN - .vmagent.proxy.DeviceDetection - UDP device detection failed java.net.BindException: Address already in use: Cannot bind
Cause: The device detection ports are used by another application on the host computer. By default, these ports are 55208 and 55209.
Action: The best solution is to stop the application that uses these ports or configure it to use different ports. Alternatively, you can configure the device and Device Manager to use different ports as follows:
Change the ports specified by the proxy.udp_device_detection_request_port and proxy.udp_device_detection_response_port properties in jwc_properties.ini on the device.
Create a file named proxyOptions.txt under toolkit-lib/lib in the Oracle Java ME SDK installation directory and add the following line to it:
-bcastports
The
and
port numbers must match those specified in the device properties (see Step > 1).
Since the default ports used by Device Manager are 55208 and 55209 you can check whether those ports are already being used:
- Open a Command Prompt window.
- Submit
netstat -aon | findstr 55208
andnetstat -aon | findstr 55209
.
If the two calls to netstat
return nothing then the ports are available. Otherwise those ports are already in use and you need to find out why, by checking the PIDs that are displayed for the ports in use.
Alternatively, just assign different port numbers, as described in Oracle's documentation shown above. If you are going to do that, first verify that the new port numbers are available using netstat
. For example, if you want to use port 55210, call netstat -aon | findstr 55210
. If no other process is using that port then netstat
will return nothing.
Update:
The following approach worked for me:
- Select Tools > Java Platforms > Add Platform...
- Click the Add Platform... button and select radio button Custom Java ME CLDC Platform Emulator and click Next >.
- Click the Browse... button and navigate to your Java ME folder (e.g. "...\Java_ME_platform_SDK_8.0").
Click Next > then Next > then Finish.

I created plugin with Qt (5.6.2)
and trying to load it but it returns null
all the time. I checked several question and also tried the solutions but it didn't work for me.
Can you take a look of the following code and see whats wrong?
DeviceManager.hpp
...ANSWER
Answered 2017-Dec-12 at 16:02Just reading posts properly can sometimes open ones eyes.
The problem is: You are using minGW with Qt, but are using a lib-file, i.e. a library compiled with the msvc-compiler (visual studio). This is not possible, as they are generally incompatible!
You have 2 options now: Either you install the Qt Kit for whatever version of Visual Studio the library was compiled for, or, if the library is open source, compile it yourself using mingw.
