Description
Arduino board: Adafruit HUZZAH32 – ESP32 Feather Board
Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.5
Story:
I am using the Adafruit IO Temperature & Humidity Example , slightly modified ( see below )
- Temperature and humidity come from a BME280 so the include looks like:
===
#include "config.h"
#include <stdint.h>
#include "SparkFunBME280.h"
//Library allows either I2C or SPI, so include both.
#include "Wire.h"
===
Issue:
A variable number of minutes after powering up the board ( but rarely longer than 30 ) the WIFI disconnects ( or the AP gets bored ).
This triggers a loop
===still working===

======
Question:
Is the lower layer supposed to handle this exceptions or is the job of the upper layer libraries to treat these and trigger a reset / reconnect to wifi?
The way it looks to me ( I'm new to this so I apologize in advance ) is that a WiFi exception is never triggered and WiFiClientSecure starts looping without an exit condition ( aka 10 retries ).
Again , if this is the wrong place to open the issue , I apologize.
Thank you!
