kandi X-RAY | openthread Summary
OpenThread released by Google is... ...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home. ...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs. ...a Thread Certified Component, implementing all features defined in the Thread 1.1.1 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.

QUESTION
I have the problem that a thread that was sent to sleep using SleepEx(INFINITE, true) does not reliably continue when an APC is queued.
The application scenario is that software A must notice when software B has installed a certain Windows service.
For this, I create a new thread, register a callback function via NotifyServiceStatusChange(), and put the thread to sleep via SleepEx(INFINITE, true).
If, during the runtime of software A, the specified service is installed, the callback function is called, the thread is continued, and finishes its run() method. Everything works fine.
But, if software A terminates without the callback function being called, I still want the thread to terminate properly.
The Microsoft documentation states this about the SleepEx function:
Execution resumes when one of the following occurs:
- An I/O completion callback function is called.
- An asynchronous procedure call (APC) is queued to the thread.
- The time-out interval elapses.
Therefore, I queue an APC to my thread using QueueUserAPC(). This works fine, my function stopSleeping() is called and executed: A breakpoint can be reached and debug output can be made inside this function.
Unfortunately, contrary to my expectation, my own APC does not cause the thread to resume running, as the call of the function callback() does.
The question is, why not?
My thread is a class derived from QThread and the stopThread() method is triggered by a SIGNAL/SLOT connection from the main thread.
ANSWER
Answered 2022-Jan-19 at 20:46I'm not 100% sure on this, given that you didn't provide a runnable example it's hard to verify.
My guess is that you're scheduling the APC on the main thread, instead of the CCheckForService thread.
If CCheckForService::stopThread is called from a signal/slot on the main thread, then it'll execute on the main thread.
So ::GetCurrentThreadId() will return the thread id of the main thread, and you subsequently end up with calling QueueUserAPC() with a thread handle for the main thread, so the APC will execute on the main thread.
So the CCheckForService will remain sleeping, because it never received an APC.
You can verify this by comparing QApplication::instance()->thread() with QThread::currentThread() inside your CCheckForService::stopSleeping method - if they're equal you scheduled the APC on the main thread instead of the worker.
There's unfortunately no officially supported way in QT to get the thread id / thread handle of a QThread, apart from calling QThread::currentThreadId().
So you'd have to store the thread id in your CCheckForService class, so you can later get the appropriate thread handle, e.g.:
QUESTION
I try to initialize 2 DTLS sessions with 2 different peers. The first otCoapSecureConnect returns OT_ERROR_NONE, the second one returns OT_ERROR_INVALID_STATE. Does OpenThread allow multiple CoAP secure connections ?
ANSWER
Answered 2021-Jul-28 at 04:31The current CoAP Secure APIs in OpenThread only supports a single active session.
QUESTION
I am trying to create a refresh button that floats on the right side of the screen that will refresh a listview
My CodeI am using the following class that will pull JSON data and create a listview for me via context.read().fetchData; on first load.
ANSWER
Answered 2021-Jun-26 at 06:20Well @pskink nailed it above in the comments
I'm leaving this here just incase someone else stumbles on this problem and needs a solution
The answer is that I didn't include the ReadContext extension
All I had to do was add import 'package:provider/provider.dart'; at the top of my .dart file and it works perfectly

Try removing final keyword from the tVars
QUESTION
So I'm just experimenting with smart pointers and how I can manage Win32 HANDLE objects with them, so I wanted to test out this simple code I wrote.
It's supposed to provide a custom deleter for std::unique_ptr to use when the smart pointer goes outta scope.
ANSWER
Answered 2021-Feb-23 at 06:16std::make_unique cannot make std::unique_ptr with a custom deleter.
You have to manually call its constructor.
QUESTION
What is the maximal number of hops (or path cost) allowed by Thread specification. How many hops are supported by OpenThread?
I found two similar questions (link1, link2) but answer is different (maybe even outdated?).
...ANSWER
Answered 2020-Dec-17 at 00:01Thread specifies a maximum path cost of 16 between routers. Link cost between routers can be 1, 2, or 4. Links to end devices are not included in the path cost calculation.
QUESTION
I'm using a Raspberry Pi 4 Model B and i want to run the Openthread Border Router application on it as a docker container. I use the command docker run --sysctl "net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1" -p 8080:80 --dns=127.0.0.1 -dit --network test-driver-net --volume /dev/ttyACM0:/dev/ttyACM0 --name ot-br --privileged openthread/otbr --radio-url spinel+hdlc+uart:///dev/ttyACM0 to start the container. I have tried the openthread/otbr:latest and the openthread/otbr:reference-device (both pushed 10. Nov. 2020) image, both were having the same problem:
The container is started successfully, but the Web-GUI is not available and no network operation takes place. Here is the logged output of the containers if called upon with docker logs ot-br:
ANSWER
Answered 2020-Nov-19 at 17:06This issue was recently fixed with openthread/ot-br-posix#614 and new Docker images have been pushed. Please try again.
QUESTION
I have a some question. I would like to use one of the USB log macros like NRFX_LOG_INFO() and NRF_LOG_INFO(). But when I set NRF_LOG_ENABLED 1 in sdk_config.h and include nrf_log.h into my file in openthread/examples/platforms/nrf528xx/src/` I get the following error:
ANSWER
Answered 2020-Jul-23 at 15:48As mentioned in Github issue: https://github.com/openthread/openthread/issues/5285
In OpenThread repository the NRF_LOG module is not usable (only stubbed). For logging purpose, you can use either OpenThread's otPlatLog functionality in vanilla OpenThread, or download the nRF5 SDK for Thread and Zigbee which gives you full functionality of NRF Logger.
QUESTION
I have the problem with compilation. After adding function call
otThreadGetMaxAllowedChildren() in the openthread/examples/apps/cli/main.c I got an error:
ANSWER
Answered 2020-Jul-20 at 15:14The otThreadGetChildInfoByIndex() is only available for FTD builds.
You should either:
Disable MTD and RCP in your build options, or
Wrap your child table code with
#if OPENTHREAD_FTD.
You can refer to the CLI code for example usage.
QUESTION
I have the OpenThread CLI application and I would like to create UDP datagram with the payload consisted of child table information.
So my question is: how to get child table info and which API should I use? I have done some research, and I consider to play with otThreadGetChildInfoByIndex() placed in for/while loop. Does it make sense??
Best regards!
...ANSWER
Answered 2020-Jul-17 at 21:17Yes, otThreadGetChildInfoByIndex() is what you are looking for.
You can find an example in OpenThread's CLI implementation.
