Hello,

I linked the three languages in each of the readme file so as the reader can jump between the different translations by clicking on the language name.

Each translation has two linked languages and the language of the current readme is not linked to a file , so as to show the current translation of the readme.

I hope this is ok, if there's something that has to be changed, do let me know, cheers!

With this PR,

From 4-Manufacturing : 2-Check Fruit from Device ,

The lesson Readme has been translated into Bengali. The placeholder .dummy file has been removed. Changed according to review. There are some problems with hyperlinks from the table. I couldn't fix that. #50

I am working on Lesson 4, Control your nightlight over the Internet - Wio Terminal. I am on step 7 of the Task - connect to WiFi section where I am asked to upload the code to the Wio terminal.

When I run PlatformIO: Upload, I get the following error message:

...
Looking for upload port...
Error: Please specify `upload_port` for environment or use global `--upload-port` option.
For some development platforms it can be a USB flash drive (i.e. /media/<user>/<device name>)
*** [upload] Explicit exit, status 1
================ [FAILED] Took 4.26 seconds ================
The terminal process "platformio 'run', '--target', 'upload', '--environment', 'seeed_wio_terminal'" terminated with exit code: 1.
...

Prior to modifying the code for this lesson, I verified that the Wio Terminal still functioned properly with the prior lesson's nightlight code.

Has anyone else come across this behavior, or have some clues about how to work around this?

Note: I am pretty sure that I uploaded the Wio Terminal firmware earlier in order to enable the WiFi settings, but perhaps there are more steps needed ?

Thank you.

I am going through the Migrate your plant to the cloud lesson. I am using the Azure CLI ver 2.30.0 on macOS 11.6 (Big Sur).

I have successfully connected my Raspberry Pi to Azure IoT Hub and have confirmed the ability to send moisture-sensor telemetry to the IoT Hub, and to call direct methods for relay_on and relay_off from the IoT Hub by invoking these methods within Azure Portal.

However, when I try to execute the steps in Task - monitor events to use the Azure CLI to monitor events that are sent from my Pi to the Azure IoT Hub, things break down. Specifically, when I run the command az iot hub monitor-events --hub-name <hub_name>, I get the following error message returned:

gather() got an unexpected keyword argument 'loop'

Here is a screenshot with further detail:

The value I am using for <hub_name> is mjh-IoT-Hub-20211122. I also tried surrounding this value with single and double quotation marks, but that didn't matter.

[UPDATE 11/29/21]: I ran the az iot hub monitor-events --hub-name <hub_name> command from a windows 10 device and it worked fine, so the issue appears to be limited to the macOS implementation of the Azure CLI azure-iot extension. Just for ha ha's, I verified that I was running the latest version of the azure-iot extension (0.11.0) on my mac . I then removed it and installed an earlier version (0.10.11). Same error :-( . I'm at the latest version again in case further troubleshooting needs to occur.

Any suggestions @jimbobbennett ? Has anyone else experienced this issue on macOS?

I am going through the Geofences lesson using a Raspberry Pi. I am using VS Code to edit remotely from a mac. The python version being used in VS Code on the mac is 3.8.2.

I already verified that the Azure function worked fine with just the iot-hub-trigger. I also verified that both function triggers (iot-hub-trigger, geofence-trigger) were working when I ran the gps-sensor Azure function locally.

In Step 10 of the Task - test the geofence from the trigger section, I have uploaded the new application settings (MAPS_KEY, GEOFENCE_UDID) and re-published the gps-sensor functions app to Azure. I am trying to verify that both function-triggers are working in Azure, but it looks like they are not :-(

The iot-hub-trigger looks like it's working (I don't see any errors when I inspect the Monitor blade in the iot-hub-trigger function). I am able to see new blobs written to my Azure storage account (although it seems to take a bit longer for them to show up in the Azure Storage Explorer).

The geofence-trigger, however, looks like it's not working. I see error messages when I inspect the Monitor blade in the geofence-trigger function. See below images for details:

Please advise....

I am going through the Decode GPS data lesson using a Raspberry Pi. I am using VS Code 1.63.2 to edit remotely from a mac with macOS 11.6 (Big Sur). The Raspberry Pi is using Python 3.7.3.

I have successfully completed the task to connect a GPS sensor and read GPS data, so I know that the GPS sensor is receiving data.

However, when I try to run the program to decode the data, I get errors. These errors occur even if I am using the sample code copied right from the code-gps-decode/pi folder in the lesson's repo. It also occurs regardless of whether I am running the code from the VS Code built in terminal, or a separate ssh session using macOS terminal.

The error message return is as follows:

Traceback (most recent call last):
  File "app2.py", line 25, in <module>
    line = serial.readline().decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa9 in position 2: invalid start byte

Note: the values for byte and position in the error message will vary between different attempts.

Here is a screenshot with further detail:

From what I can guess, it looks like the data being read from the GPS sensor includes different characters at different positions which were not encoded using utf-8, or there is something else wrong with the decode function in the pyserial library.

@jimbobbennett , full disclosure: I am not a Python expert, so it's entirely possible that I could be doing something wrong, and that this is a (hopefully) easy fix. I do think that it is something that other students will come across, however, so hopefully you provide some guidance. If you need more information or need me to try some other tests, just let me know.

[UPDATE 12/29]: After further testing, I can get the code to run after trying multiple (sometimes 12 or 13) times. It looks to me like the serial.readline().decode('utf-8') method will sometimes get a partial message as its first line, then chokes because it doesn't know how to deal with an incomplete line/format. @jimbobbennett, is there a way to modify the sample code in this lesson to validate that the first line read from the GPS serial interface is a complete, well-formatted message before trying to call the decode method? To me, the lesson should yield code that produces a consistent output/experience each time, otherwise how does the student know if the error is coming from a bad library, or something that they may have done wrong?

I'll finish it this weekend.

Hi,

first of all: awesome project! I plan to run through this with a bunch of students starting the new school year (September). I figured I'd run through it myself first though.

In lesson 4 it becomes rather unclear what's to be expected when it comes to installing the virtualenv. It says to 'skip this step' when you're running on a rPi locally - which we will be.

Either it's missing instructions on what to do on a rPI or it's missing instructions that you'll be required to install python3-venv on the device.

My suggestion would be to skip this step altogether on the rPI and simply include instructions on how to open a second terminal window.

Please let me know your thought and I'd be happy to submit a PR with the changes.

Cheers,

Peter

Hey,

I've added shields to the main readme as well as to the Chinese, Turkish and Bengali translated readme. I also updated the Translations.md.

Hope it's ok !

I hope it is ok to have projects for beginners and hence added a project. Please merge it, and if something is need to be added please let me know. :) Thank .

My understanding is that if someone has an IoT Edge device, that IoT edge device is basically a place where you could run cloud functions on the local network. This IoT Edge device could also act as a gateway for other IoT devices on that network. In other words, if those other IoT devices needed cloud services, they would direct their requests to the IoT Edge device. That Edge device could either handle the request for cloud services itself (on the Edge), or it would proxy these request to actual cloud services.

If this understanding is correct, then I think the following diagrams in 4-trigger-fruit-detector lesson should reverse the position of Edge Device and Device in the Things column such that the Edge Device is the Thing that is communicating with components in the Insights column. In addition, within the Things column, the Edge Device, rather than the normal IoT device with the sensor, should be the component that connects to any AI services.

Hi guys, I found the code in lesson 3(senors-and-actuators) not work in my browser.

I tried both in win10 and macOS, and both old version or new version of counterfit.

The situation is when you open your chrome dev tools and lookup the websocket messages, it always 2 and 3, no other messages like actuators data or connection data send to the browser. So the led on/off is not change.

I try to modify the source code of counterfit like following, then it works.

@socketio.event
def set_and_send_connected(connected:bool = True) -> None:
    global is_connected
    is_connected = connected
    emit('device_connect', {'connected' : is_connected}, namespace='/', broadcast=True)

I am not familiar with websocket, I don't know why, but I hope this can help other guys.
