I'm following the tutorial Connect a devkit device to Azure IoT Central, https://docs.microsoft.com/en-us/azure/iot-central/core/howto-connect-devkit
The devkit isn't sending any data, the screen says IoT DevKit, PnP Enabled Running 192.168.1.81
@gmwill92 Hi, you can follow this link https://docs.microsoft.com/en-us/samples/azure-samples/mxchip-iot-devkit-pnp/sample/ to connect to Azure IoT Central. Make sure add an IoT Central application created from the Preview application template. If you have any questions, show your output log in serrial monitor and maybe I can help you.
Hi, hopefully a simple question. I just tried the IOT DevKit for the first time, following the getting started example using VSCode. Everything went smooth up until running the code on the IOT device. The display is stuck on Running... -> IoT Hub
I checked that the device is configured in Azure and it is. If I try to monitor using serial communication (the powerplug in vscode) I get the following error message:
[Starting] Opening the serial port - /dev/cu.usbmodem143203
[Error]Error: Error Resource temporarily unavailable Cannot lock portAlso when I monitor communication to endpoints on Azure there is no traffic. I would expect that the blue led for Azure connection should light on the IOT device but it doesn't
I should mention that I try to follow the tutorial on a macbook. All software is at current version (VSCode, IOT extension, Arduino extension and Arduino IDE
@rickpeters Hi Rick, I encountered the same problem with the getting started example like you a few days ago. The screen of the devkit board showed Running...-> IoT Hub, but didn't go to the next expecting screen of message counts. For me, I just ignored this and continued with the guide using arduino IDE to upload example project code onto the devkit board, and luckily enough I saw the expecting green of message counts. So you can try it . For the specific problem you mentioned, I guess maybe the newest firmware just don't work as we expect.
Hello guys, I want to understand once one build some solution around Azure DevKit - how they port it in production from hardware perspective. I mean an embedded device should contain only specific things and all the sensors on DevKit might not be all needed in every application. How do you go about making an hardware port then ?
@jyotendra As I know, the porting part should be implemented by yourself. You can treat porting as a common problem, and porting is all about adaptation. You need to implement the APIs developed with Azure DevKit with the lower APIs provided by your hardware. If your production hardware is some standard in industry compatible, that would save a lot of time. For the "sensors not be all needed" part, I think this is a problem you should make your own decisions.
Thanks @IvanJobs that was helpful. That matches my thought process and after reading your comment I have decided to use top-down approach, beginning from choosing hardware that could be ported easily and then going with developer kit. ST Electronic's boards seems compatible with arduino, like iot-dev-kit - I think will give it a try first.
Hey folks, just started with the dev kit and working through Azure's 'Getting Started' doc. Experiencing an issue when trying to upload code from VS Code to the dev kit from my MacBook. The guide explains that an ST-Link Driver isn't required for Mac OS, but it doesn't give me the option to select a Serial Port to communicate through on vs code. When I attempt to upload the code, vs code tells me to select a serial port but only gives me a dead button which has no function. help pls
Hi, I'm having an issue connecting the serial port. I bought the MXChip microsoft IoT starter kit. I keep getting the exception, "No serial port was selected, please select a serial port first". I cannot find a way to actually set the port. I do have the v2 software installed as per the documentation.
Yep, Resolved by downgrading VS Code to the Jan 2020 version 1.42.1.
The Feb 2020 version 1.43 had a bug where the Serial/Com port (ST Link USB) was not working.
Hello, I followed https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-arduino-iot-devkit-az3166-mqtt-helloworld and get it up and running. Now I want to connect to another MQTT broker via encrypted MQTT at port 8883 with a ca-certificate. Is this possible with a DevKit? Any example code available?
Hi, I have a 8 Ω speaker, can I connect it directly on the speaker conductive dots on the az3166 board or I should put a resistor ? I can't find the info on the audio chip pdf https://datasheetspdf.com/pdf-file/1134752/nuvoton/NAU88C10/1
Yes I am working on IOT Edge, how can
I help you, please let me know
DO you have any recommand framework to provide?
MxChip Az3166 OTA tutorial...does not go past checking 1.0.0 version (step 4 in the "start OTA firmware update " section - https://docs.microsoft.com/en-us/samples/azure-samples/mxchip-iot-devkit-firmware-ota/sample/) --- there are NO errors in Azure portal...how do I know where it's stuck? Thanks!
Hello! A couple small details I noticed for updating:
https://docs.microsoft.com/en-us/samples/azure-samples/mxchip-iot-devkit-get-started/sample/
1) See above image for vs code complaint.
2) Should this read "Expand the AZURE IOT HUB DEVICES pane on the left" instead of "on the right"?

Tutorial was a great way to get introduced to MXChip and Iot Hub. Thanks!
i need to set the system properties on the MXCHIP to make it work with Event Grid downstream. I could not find anywhere in the DevKitMQTTClient lib an API to do that. i see that this client wraps or reuses the iothub_device_client_ll, which can do that with IoTHubMessage_SetContentTypeSystemProperty and SetContentEncodingSystemProperty. Could someone push in the right direction here ?
