I am using a micro:bit device with ESP8266 for a IOT project, but cannot connect thingspeak recently.
The conncection is unstable, I can hardly connect to thingspeak for days, somehow it works last night for 30 mins and then it fails.
The program does not change and I have included a 25 sec delayed between each data sending.
Please advice why and how to fix it. Thank you.
I am using the ELECFREAKS IOT:bit Expansion Board with micro:bit to record data, it worked normally but in this week I tested again, and discover no data is uploaded to the channel ie.no entries in channel. The code in makecode are the same as before and the wifi is work, I cannot find the reason that cause this failure.
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.
Dear all, I am using the micro:bit with ESP-01s and the CO2 sensor to monitor indoor air quality. Thingspeak cannot show the data eventhough the ESP is connected to the wifi (checked with the router). Failed to talk to my ESP even I have setup a new channel many times. Can anyone advise me what to do?
Thank you for your help in advance.
