Hi I am trying to hook up the DFRobot Environment shield for Microbit (https://www.dfrobot.com/product-2194.html) . I have used it in the past at home. This time I am using it at the school where I am teaching. I have setup a hotspot using my phone and connected the device (the wifi light goes green) and I can see the device connected on my phone. But the data doesn't pop up on thingspeak channel. I have attached the code below. The write key is generated by Thingspeak API. The username and password are accurate to what I am using (wifi color goes green on the shield so I know its connected). When I try ping thingspeak.com I don't get any response. Is that blocked by Thingspeak usually? Thanks for your support. Sorry I couldn't embed the makecode code so attached a picture. But I don't really think anything is wrong with the code.

Hi all, I am trying to create a complete learning unit online using laravel. The unit of work is in Internet of Things. Hardware will be provided to students - Its a microbit plus the DFRobot Environment science expansion kit (https://www.dfrobot.com/product-2194.html) . All the video tutorials and project work is assigned via the laravel lms.They will log into the lms via their microsoft logins. My next step is to simplify the process of users accessing the mathworks account. I would like to pre assign channels for students with API keys to write sensor values from each of their microbit shields to the cloud. Has anyone tried to do this or has any suggestions how to? The advantages of students having their own channels on my account is for me to monitor how they are progressing. These are year 9 students at high school who have never done any IoT or mathworks/thingspeak related content before. User generation for channels for IoT Shield You can use the create channel API to create new channels for your students. The response to the request has the API kiy and channel ID in it. microbit dfrobot iot sensors api laravel lms

I have tried various methods of uploading numeric data to ThingSpeak using a new DFRobot SIM7000E Arduino shield with no success. I have successfully proven that the shield will accept AT commands and interfaces with my local Telco network (Telstra - Australia). Every example code that I have used to date either falls over, or I do not understand the required setup variables. I am looking for some simple (commented) working code that relies on API and Channel No, as inputs. I have little experience with Iot and networks in general. Thank you Jeff
