    Hi take a look at a short film that Deepk and I (Nik) have made in LinkedIn
    Please check #iotc2c or #iotCoast2Coast in linkedIn
    https://www.linkedin.com/company/azure-iot-coast-2-coast
    Please follow because we will be posting more samples and short film
    @ajreply Hi
    soon IoTCoast2Coast will publish a shrt film on how we have set up IoT devices like MXChip to a Wifi

    @ajreply Hi IoTCoast2Coast sounds good.

    In the remote monitoring example, it uses psig for pressure unit
    I'm pretty sure the pressure unit is "hPa"
    Can someone point me to the repo? I can submit a PR to fix

    I have written a sample application for the IoTKit capturing ALL sensor data but with a focus on dead-reckoning of motion. It is still in late-stage development, but I would like to share it soon. How would I go about doing that?

    In order to demonstrate the AZ3166 in a portable device scenario, I needed to find a suitable portable power source. I have settled on a small-form-factor USB power supply (the Cheero CHE-056 Power Plus 3000mAh 1A model). Main features which make this suitable:
    • exactly same size (WxH) as the AZ3166 and only 12mm deep
    • the low-power cut-off threshold is only ~70mA, which means so long as the board is connected to wifi, the power supply does not switch off. Otherwise it switches off after 30 seconds
    • holds sufficient charge to run prototype applications for more than 36 hours - more if my programming were focused on power conservation
    • limiting factor is the sole USB micro B power supply to the board. If there were a LiPo-friendly connector (e.g as with Arduino MKR1000), then options for portable power would be much greater

    @lowndesc , you could follow https://github.com/microsoft/vscode-iot-workbench#contributing to contribute new example for IoT Devkit. You could also check the existing contributed example: https://github.com/jimbobbennett/InternetConnectedFan/

    Hello, I have followed the MSBuild announcements and would like to play with the IoT plug and play feature.
    I know that the MXCHIP can be easily integrated in IoT Central, but I would like to test the code-generating feature presented at Build this month.
    Can I do this with the MXCHIP ?
    According to the Azure Iot Solutions catalog it is not "IoT Plug and Play certified" (link here) but there is a new ESP32 board pictured among the certified devices. Maybe I should get one of these new boards...
    Arthur Ma
    @ArthurMa1978
    @xaviermignot PnP is announced at //BUILD, but currently it's still private preview and only can share with under-NDA customers
    MXChip is definite the preferred device, and it's the only MCU device we used for service and tooling development now
    Xavier Mignot
    @xaviermignot
    ok thanks @ArthurMa1978, I'll wait for the public preview then :)

    Quick question from a new guy: I'm working with an MXChip and a very slightly modified version of the firmware from IoT Central, and finding that the board is randomly rebooting itself (presumably crashing?) every 30-60 seconds. Edits to the code were to change the duration of the telemetry uploads and to add a few Serial.print statements with no formatting (i.e. no opportunity for format bugs). I can see the output from the Serial monitor but so far I can't figure out what's causing the reboots. Can anyone point me to troubleshooting resources or techniques? Is there any way to get a crash dump or get the debugger to break in when the crash happens?
    Arthur Ma
    @ArthurMa1978
    @misterfoo does the default firmware work well?

    I would like to make a direct method call to the device (DeviceMethodCallback)
    how can I display the payload that is received on the device? I can see a payload variable, but not sure how to use it. (I know zero c++, which doesn't help)
    I tried Screen.print(1, *payload, true);
    Xavier Mignot
    @xaviermignot
    @danshoubs have you tried Screen.print(1, payload, true); ? (without the *)
    Dan Shoubridge
    @danshoubs
    @xaviermignot yes, tried a few combinations, without the *, I get:
     initializing argument 2 of 'virtual int OLEDDisplay::print(unsigned int, const char*, bool)'
         virtual int print(unsigned int line, const char *s, bool wrap = false);
                     ^`
    ideally, I want to convert it from json to an struct and output specific values, but just displaying whatever raw text I send to it would be a good start.
    Xavier Mignot
    @xaviermignot
    @danshoubs if it's just for debugging purpose I'll suggest to use Serial.print and from VS Code see what is sent to the Serial Monitor.
    Xavier Mignot
    @xaviermignot
    Or if you want to stick with the screen, I have looked into the samples for some code who display variables on the screen, I have found this in the translator sample:
    char temp[33];
    int end = min(length, sizeof(temp) - 1);
    memcpy(temp, text, end);
    temp[end] = '\0';
    Screen.print(2, temp, true);
    And that in the Shake for a tweet sample:
    Screen.print(1, &msgBody[msgStart], true);
    Where msgBody is a char array and msgStart is an int
    Dan Shoubridge
    @danshoubs
    @xaviermignot that was a compile error, rather than a log whilst it was running, but I am logging in the way you suggest to help me, e.g. LogInfo("Message recieved from IoTHub");
    I managed to get the following working now, but thanks anyway:
    ...
    JSON_Value *root_value=NULL;
        root_value = json_parse_string((const char*)payload);
        JSON_Object *root_object;
        if(json_value_get_type(root_value) == JSONObject)
        {
            root_object = json_value_get_object(root_value);
            const char *message = json_object_get_string(root_object, "message");
    ...

    Hmm does anyone know about the free MXChip DevKit, I got an email about one but only see links to purchase from Seeed
    rbeyea
    @rbeyea
    @samlii same here. got an email that says "Sign up for a free IoT MxChip DevKit and start simplifying your processes." but I see no where to sign up. Just the link to purchase a kit.

    @liydu
    @samlii , @rbeyea , can we know the details about that email? As our team has not sent such email recently, we want to learn more about the situation here. Thanks.

    Hello everybody, how are you doing ?
    Do you know why this sketch https://github.com/microsoft/vscode-iot-workbench/blob/master/docs/iot-devkit/devkit-mqtt-client.md gives me gibberish instead of a properly formated string ? For exemple : "üs 5m m m m m m m J"
    ashtez
    @ashtez
    ok, problem resolved, the default code is garbage, use this one : https://github.com/eclipse/paho.mqtt.embedded-c/blob/master/MQTTClient/samples/arduino/Hello/Hello.ino

    When I connect the devkit to a
    When I connect the devkit to a battery bank, the programming led starts blinking. What does that mean?
    Renhe Li
    @lirenhe
    @ladeak87_twitter , The programming led blinks when uploading firmware into devkit. Did this happen when you connect it to your computer?
    @ashtez , I checked the devkit-mqtt-client and did not see any strange string. Could you share the full output? The Baud Rate should be set to 115200.
    &ladeak
    @ladeak87_twitter
    It blinks much slower say 1/sec

    anyone have worked on Azure Speaker Recognition?, i need help for a demo
    Renhe Li
    @lirenhe
    @ladeak87_twitter could you try to upgrade our firmware first? https://microsoft.github.io/azure-iot-developer-kit/docs/firmware-upgrading/ If that doesn't help, this could be a hardware issue and please contact the seller.
