Example adafruitio_11_group_pub causes crash on Huzzah32 #114

Closed zencow closed 4 years ago

zencow commented 4 years ago

Hi...

I attempted troubleshooting on the discord server about this, but upon looking further, I found that the error applies to the stock example as well as my more complex and messy code. ;)

I used a plain Huzzah32 Feather connected only to an Adafruit Lipo and the USB connection to my computer for programming with the Arduino tools.

  1. loaded stock example 11 from Adafruit IO Arduino version 3.4.0
  2. The only changes I made are the 4 lines required in config.h for my AIO and WIFI credentials.
  3. The code compiles and programs successfully, then runs until after the first set of data is published, then crashes a few seconds later.

Serial output:

zencow commented 4 years ago

It should be worth noting that the Group and Feeds were created automatically and a "0" was published for each Feed on each reboot of the device. The program always crashed during the 2nd call to io.run() before it got the chance to publish any incremented values.

@zencow This is the same error as https://github.com/adafruit/Adafruit_IO_Arduino/issues/111 and I didn't understand why this was crashing until I looked at the group subscription sketch closely.

The comparison if (strcmp(cur_cb->feed, d->feedName()) == 0 || cur_cb->feed == NULL{ fails due to the callback attempting to obtain the feed's name (cur_cb->feed) because the _groupCallback callback was never properly init'd since the setup() in adafruitio_11_group_pub.ino never calls onMessage, which is used to initialize the _groupCallback (https://github.com/adafruit/Adafruit_IO_Arduino/blob/master/src/AdafruitIO_Group.cpp#L309).

Also, _groupCallback is never NULL, so the check within onMessage which initialzes _groupCallback also fails. This is why the subscribe example fails in the same part of the code, while it properly sets up the message handler.

I'll create a PR for this today.

I tested the patch at "Fix ESP32 Groups Crash #115" and it worked for me. No more crashes.

I got the latest library update (v 3.5.0) from the Arduino IDE and it ran 10 cycles before I killed it. ;) Kudos!
