Azure IoT Hub Basic tier is not supported

The current guides publish a device twin property from its main mqtt loop, which is not allowed if using a Basic tier. The results in a disconnect and all following telemetry failing.

DNS client fails to initilaize

I'm following along the tutorial for the MXChip

I keep getting the following error:

I cannot find any suggestions for this issue.

Any ideas?

Changes to TLS certificate for Azure IoT Hub and DPS endpoints

Hi, do these coming changes require us to update the code in this demo project for it to continue to work after Feb 2023?

Thank you ! Sergio

Connecting AZ3166 to an IoT Edge device

I am trying to connect my AZ3166 device to IoT Edge by following this tutorial

https://learn.microsoft.com/en-us/azure/iot-edge/how-to-connect-downstream-device?view=iotedge-1.4

Where should I put my root certificate file?

Any help would be most appreciated! :)

Different results with two CMake projects for same sources

Hi,

I am facing a weird issue. I have made two projects with same source files that use CMake for compilation.

1. First project has CMakeLists.txt in multiple subdirectories.
2. Second project has a single CMakeLists.txt

Both projects using the same tool chain and compilation flags. But the first project hard faults when trying to execute _tx_thread_schedule();. The second project works without any issues.

I have followed the project structures that are similar to the examples in this repo. Which is that, I create libraries for threadX, netxDuo and STM32Hal.

I am wondering what could have gone wrong.

I would be happy to share the sources.

Device: STM32H723
Example project: TCP Echo Client

For reference, please take a look at the image below for the debug trace. Note that the WWDG is not enabled in the project.

Controlling other devices

Hello,

I have the sample up and running on my MXchip with Azure RTOS, but I am looking for a good example how I can control for example a motor. Normally I could enable pins on this way when developing for the MXchip (old school via Arduino/ VS Code):

if (temperature >= temperatureThreshold)
{
digitalWrite(PB_0, HIGH);
}

How can I achieve this with this RTOS example?

Could you please help provide me some code examples about how to collect decibel using Azure-rtos?

We are using AZ3166 device with this repo https://github.com/SibeeshVenu/MXChip-Azure-IoT-Arduino
It can collect decibel telementry. This repo based on the DevKit https://github.com/microsoft/devkit-sdk/releases/.

Since it didn't include Digicert G2 certificate, when we migrated to G2 certificate, the device cannot connect to IoT Hub using the old repo.
We must using Azure-rtos to re-flash our AZ3166 device. However, the repo Azure-rtos only has basic telmentry such as temperture and humidity, cannot collect decibel telementry.

Could you please help provide me some code examples about how to collect decibel using Azure-rtos?

ST's netxduo of wifi version failure in DPS

Hi,

I am Nuvoton's engineer and on porting azure iot, based on azure rtos 6.0.1, onto Nuvoton's NuMaker-IoT-M487 board, which is Cortex-M4 MCU and has one on-board ESP8266 wifi module. Because ESP8266 WiFi module has its own stack, I follow ST's reduced netxduo for wifi to substitute for the standard one. Adding ESP8266 wifi driver, it can work well with this netxduo of wifi version.

To connect with azure iot, I port the sample sample_azure_iot_embedded_sdk. Without DPS enabled, I can successfully connect with azure iot hub. But after enabling DPS, it fails because the netxduo of wifi version disables the nx_tcp_socket_establish_notify(...).

https://github.com/azure-rtos/getting-started/blob/829122217a643ce60d0b468c71358fcb9522aa38/STMicroelectronics/STM32L4_L4%2B/lib/netxduo/src/nx_tcp_socket_establish_notify.c#L78

Do you have plan to enhance the netxduo of wifi version to support use case like DPS here?

Connection lost after 1h

I used the given documentation to connect my DevKit to IoT Central.
https://docs.microsoft.com/en-us/azure/iot-develop/quickstart-devkit-mxchip-az3166
Following the tutorial, my connection gets lost after one hour, I assume it is due to the SAS token renewal?
Any quick fix to this?

I have appended the Termite log:

Disable interrupt in ST's netx wifi driver?

I have a question with protection of ST's netx wifi driver. In https://github.com/azure-rtos/getting-started/blob/master/STMicroelectronics/STM32L4_L4%2B/lib/netx_driver/src/nx_wifi.c,

nx_wifi_ APIs have been protected with:

Then why needs disabling interrupt TX_DISABLE

How pinch AZURE_IOT_NX_CONTEXT to send new state of device properties to IoT Hub

Hi, I am trying to change the reported ledState in device twin when I change it in the actual device (mxchip AZ3166).

If I send this message to IoT Hub from nx_client.c when a device button is pressed, I think nx_context is not ready and the packet fails on tls packet error checks.

It works by changing a bool in nx_client.c when the button state changes and setting up a callback in azure_iot_nx_client.c that is executed by client_run() in azure_iot_nx_client.c. However this creates unnecessary overhead checking the button status constantly. Unfortunatly including nx_client.c to azure_iot_nx_client.c doesn't work to pick-up device led state variables.

Storing AZURE_IOT_NX_CONTEXT at nx_client.c from a prior use when a callback occurred threw the same packet error checks.

Is there an easier way to pinch AZURE_IOT_NX_CONTEXT at nx_client when a device button is pressed?

Thank you for your help

The Invoke method SetLEDState returns 200 code and does not change any of the LED state

The SetLEDState method is not returning 204 status as mentioned in the document instead it returns 200 and I do not see any change to any of the LEDs on IMRT1060 EVK board

MxChip Application Device and WIFI Configuration

The sample for MxChip app requires the developer to set build time configuration such as Wifi and Device connection strings in the 'azure_cofig.h" file. This means that the app needs to be built for each and every device separately. Instead, is it possible to build the app once and configure network settings externally from windows 10? Could you please advise how and where the sample needs to be modified in order to acheive this?
Thank you.

STMicroelectronics update guide to use STM32CubeProgrammer

The current guide are using the ST-Link utility for programming the device.

The recommended tool is the STM32CubeProgrammer as this is the successor of the ST-Link utility.

CommonMark standards require a space between triple-tick and the language name.

This is a very low priority issue but should be noted.

I note I have commented out // #define ENABLE_DPS as per the documentation.

My guess is that IOT_DPS_ID_SCOPE may need to be provided in azure_config.h. However this document makes no reference to IOT_DPS_ID_SCOPE and it does not show in Azure IoT Explorer.

I see in documentation to connect with Azure IoT Central that this param would be provided, but with Azure IoT Explorer it is not the case.

versus Azure IoT Central documentation where scope would be provided:

I then also tried to register the IoT DPS as per documentation and removed the comment from // #define ENABLE_DPS and added scope and dps id in azure_config.h, but termine throws.

compile error on B-L475E-IOT01A board

Hello,

I was following this guide to compile it for B-L475E-IOT01A board, but got errors like:

../lib/netx_driver/src/es_wifi.h:253:22: error: field 'IO_Init' declared as a function
253 | IO_Init_Func IO_Init;

the code is:
typedef struct {
IO_Init_Func IO_Init;
...
} ES_WIFI_IO_t;

IO_Init_Func is defined as:
typedef int8_t *IO_Init_Func(uint16_t );

It looks good to me, any ideas on this error?

SNTP timeout

Hi, I was following this tutorial & I was stuck at "Confirm device connection details" step 7, my console showed issues with SNTP server timeout, restarting client, & it stuck in a loop as below:

I have no idea what could be the reason, thanks for any help in advance.

Move dependencies outside of the build directory

Since this project is tightly coupled to threadx repos it would be appreciated if you would replace the non-standard CPM cmake module with standard git sub modules that are not located under the build directory. CPM is just unnecessary complexity, and makes integrating with existing development workflows (not CI workflows) difficult.

Callbacks not working on STM32L4 Disco

I am using the unmodified getting started repo. I have an STM32L4 discovery kit. The application works fine for sending the telemetry but fails for callbacks (C2D, desired prop, twin prop) except invoking methods.

Legacy mqtt vs nx client

What is the difference between the legacy mqtt client and the nx client? What will be the benefits for me to switch to the nx client instead of the legacy mqtt?

Sending telemetry to IoT Hub fails after SNTP time update

Using both MXChip and STM32 devices, I noticed the following behavior (see the attached file for logging information):

MXChip

• After an hour there is a SNTP time update
• Shortly after, the device disconnects from IoT Hub
• This is independent from interval times.

STM32

• Interval time > 240 seconds
  • After sending a few telemetry messages successfully, the device gets disconnected from the IoT Hub with 0x0002000c code.
• Interval time < 240 seconds
  • After an hour there is a SNTP time update
  • Shortly after, the device cannot send telemetry messages anymore, but it stays connected to the IoT Hub

The behavior above was repeatable, at least for 3 different runs with different interval times.

I wonder if the difference in behavior on STM32 with different interval times is caused by keep alive processing as documented here.

I cloned the getting_started repo master branch on Dec 10.

Screen.draw() is offset by one

Not sure if this the correct repo. The faulty code is bundled in stm32f4/2.0.0/system/libdevkit-sdk-core-lib.a but I can't find the source.

I noticed that when using draw(), the bitmap is not printed correctly. There is always a one pixel offset on the left. If the bitmap is not as wide as the display, then it shows a small gap. If the bitmap is supposed to fit the display, then it will wrap around and show the last column at x = 0.

Here's a picture of the issue. The horizontal line is made of underscores, showing that the problem does not occur when using print(). However one line below, the vertical line is one pixel to the right, whereas it should be all the way on the left.

void setup() {
  Screen.init();
}

void loop() {
  // Print some underscores for reference
  Screen.print(1, "________________");

  // Draw a single vertical line at x = 0 below the underscores
  unsigned char bmp[1] = { 255 };
  Screen.draw(0, 4, 1, 4 + 1, bmp);
  
  // Loop forever
  while (true) {
    delay(1000);

How can I get IoT Hub Events to subscribe to property updates

IoT Hub Event does not receive recorded property changes in the device twin. For example, property ledState is updated by the actual device (with patch) and the device twin updates the reported property, but the IoT Hub Event does not receive the event. This limits me in passing this property change to a digital twin with an azure function.

The IoT Hub Event does not show updated properties, unlike telemetry which IoT Hub Event receives. Considering IoT Hub Event only receives Device Created, Deleted, Connected, Disconnected, Telemetry Event Types, how can I get IoT Hub Events to subscribe to property updates?

Further description:

The actual device sends packet (MQTT function _nxd_mqtt_client_publish_packet_send) and I can see this logged in Termite: $iothub/twin/PATCH/properties/reported/?$rid=1121{"ledState":true} . The hub successfully responds with 204.

This is my device as shown in IoT hub and the device's ledState (reported) property is updated to true when I press button A in mxchip:

I have commented out telemetry messages in the code so only recorded property changes are sent to IoT hub but property changes don't show for Events:

MxChip Application Telemetry nested Json

How can I create nested json telemetry data using the 'nx_azure_iot_json_writer_append_json_text' API in MxChip application? I would like to deserialize telemetry data from the Azure function (IoT hub Telmetry data trigger) to the MxChipDeviceData class as given below. I am not sure how to implement this in the Mxchip application code. Please advise.

public class MxChipDeviceData { public MxChipSensors sensors { get; set; }; public MxChipMagnetometer magnetometer { get; set; }; public MxChipAcceleroMeter accelorometer { get; set; }; public MxChipGyroScope gyroscope { get; set; } ; public static MxChipDeviceData ToObject(string json) => JsonSerializer.Deserialize<MxChipDeviceData>(json); }

arm-none-eabi-gdb.exe

Good morning;
I was following the video: "Getting Started with IoT devices and Azure" (https://www.youtube.com/watch?v=MFGqlNeTWHk&list=LL&index=142&t=522s) but when I am trying to use the debugger to run the applicaiton I get the next error:

(OpenOCD GDB executable "arm-none-eabi-gdb.exe" was not found. Please configure "cortex-debug.armToolchainPath" or "cortex-debug.gdbPath" correctly)

I would like to ask if by any chance I missed something or if there are any advices you can give to me to solve this problem.
Thank you very much.

Sending telemetry to IoT Hub fails after SNTP time update issue is back

Hello

The previously closed issue #170 is back.

The problem was fixed with Azure IoT middleware reconnect logic #177
But recently this reconnect logic was removed #265

Now the previous problem is back.

I couldn't find the reason why this fix was removed.

My network is set-up for WPA2; I'm assuming AES (but I've tried forcing-setting the TKIP flag with WPA2 just in case, which is no better), and the key (password) is definitely correct. What could I be missing? What should I check next?

mxchip press button send led_state to to Azure IoT

Can someone share an example or guidance how I can send the property led_State when a button in the mxchip IoT device is pressed the signal is sent to Azure IoT?
I can light led in board_init.c:

At board_init.c
weak void button_a_callback()
{

//WIFI_LED_ON();
//AZURE_LED_ON();
//USER_LED_ON();
if (BUTTON_A_IS_PRESSED)
{
    val += 32;
    if (val > 2047)
        val = 2047;
    RGB_LED_SET_R(val);
    //RGB_LED_SET_G(val);
    //RGB_LED_SET_B(val);

    printf("\tLED is turned ON\r\n");

  properties_complete_cb();//how can I call this function in nx_client.c from ?
}

}

At nx_client.c I want to execute when the button is pressed:
azure_iot_nx_client_publish_bool_property(&azure_iot_nx_client, NULL, LED_STATE_PROPERTY, arg);

How can I link these two c functions, meaning from button_a_callback to call nx_client.c azure_iot_nx_client_publish_bool_property?

Thanks a bunch
