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.

The Thingspeak Configure key piece of code needs to be in the forever loop rather than onStart .

Are you able to update the channel using the GET command in your browser address bar?

Click on your channel view and use the API keys tab to get the syntax on the right hand side for "Write a channel feed"

Also, we generally reccomend not sharing your API keys, since they are a password to channel updates of a sort. You may wish to redact the above.

Hi Christopher, thanks for the answer.

The GET command doesn't seem to pull any data either.

I have a strong feelings its something to do with their (DFRobot) extension library for the module and not Thingspeak. I have emailed their tech support.

That screenshot isn't my data, rather a screenshot of the tutorial they provide which is on the public domain already.
