ESP32 based board won't load Adafruit IO code & errors inclu

by Sam43054 on Tue May 28, 2019 4:35 pm

===================================
edit: troubleshooting it also does not want to compile for The Feather ESP32 *not sure if that helps with someone being able to answer
===================================



Can anyone help with reviewing the code and error messages trying to upload a modified example of "adafruit_07_digital out"

Platform Mac OSX 10.12.6
Arduino 1.8.9

The latest Adafruit IO, MQTT Libraries


Can not get the below code to load on the "New M5 Stack" from the Adafruit Store --- a ESP32 based board

https://www.adafruit.com/product/4178

background
I've gotten the example to work on Adafruit -- ESP32 ESP8266 and WINC but I can't get it to work on a M5

Could not include all of the error message -- due to max limitations

Re: ESP32 based board won't load Adafruit IO code & errors i

by Sam43054 on Wed May 29, 2019 7:31 am

I’ve also tried on another Mac.. same MacOSX .. Arduino 1.8.7

It compiles the basic “blink” sketch just fine but I get the same exit status 1 for anything in the Adafruit library — for ESP32 or ESP8266

I’ve tried the most recent Adafruit IO and have gone back into the previous ones. Same
Error

My thoughts are since it can do the blink sketch there is something it doesn’t like with the Adafruit library? Or a dependent library? MQTT?

>> All was fine before I updated boards for ESP32 ... before this error I could use any example IO sketch on either a ESP32 or ESP8266 and they worked magically

Could you post the compilation output with an ESP32 or ESP8266?

We did change the Adafruit IO Arduino library recently with a breaking change for the ESP8266.

Please make sure you are using the following configuration:
* ESP8266 Board Support Package 2.5.1
* Adafruit IO Arduino Library v3.2
* Adafruit MQTT Library v1.0 (or above)

Did the above! Thanks for the tip. It runs okay now on the ESP8266.. But I need help with ESP32 still (trying to upload to a M5Stack Core)

I included a text file of the compilation output.... please let me know if the file is not what you are looking for... I tried to paste it in here but this forum has a max character count and it exceed it :(

Got it!!!

I just played around with backdating libraries. And got it to work on Arduino 1.8.9

You mark as solved. Big help with what Adafruit IO and MQTT to start out with. it felt like over 100 possible combinations between all of the libraries

It looks like the ESP32 Core has differing function signatures in some methods relied on by ArduinoHTTPClient. For now, downgrade the ESP32's firmware version to 1.0.1.
