Okay first some background information: I got this project for Christmas this year -
It's the Esspressif ESP32 board. I was able t successfully build the first demo project which is just a weather display pulling from an API online. The issue comes when I follow the next two tutorials. Neither one of the tutorials give me any errors when compiling them. I have TRIPLE check my wiring on the breadboard and have tried running things when the ESP32 is not connected on the breadboard.
I am a new user so I can't upload the PDF containing the tutorial. But what I will note is that the code was already written for me and again I get no compilations errors. The only changes I was asked to make to the code was to input my API keys.
I even took the extra step and re-unzip the source and tried again. success on compile and upload to the device.... and I get nothing on the display and no data on the API keys and nothing on the serial monitors.
Just looking for help to figure this stuff out and see what other debugging methods I should try!
Sorry additional details - So the first tutorial I get a full display on the onboard display. It updates and all that stuff. The other two tutorials, one is a Bluetooth one where it connects to your phone. I can connect it to my phone but it does not update the phone app. When I try and upload the final tutorial its suppose to send data to thingspeak and I don't see anything reporting to any of the dashboards I have there either.
Pairing worked... do you know if there is a password to use the app, or does the app need to have a value from the ESP32 hand-typed (as opposed to discovered in a command/response)?
Project 2 seems to be on a computer browser, not a phone app.
Uh I didn't see anywhere for a password to connect to the app or connecting to the ESP32. And yes Project 2 is on the computer but its not sending data at all. As for ensuring thingspeak working with the sketch, it was already built into the tutorial source code. I will take a look around the Thingspeak hang outs to see if thats the case. Thank you so much for continue help here!
Often, old code gets shipped with a product (or remains on the internet)... while hardware and software gets updates. I have been reading on this forum ESP32 latest release has troubles (search this forum), and returning to an earlier version of core/libraries is the temporary fix until Espressif fix it.
