Turns out the problem is with the newest ESP32 firmware.

esp32-20190617-v1.11-47-g1a51fc9dd.bin . -- this version has bugged urequests


esp32-20190529-v1.11.bin . -- this version working perfect

urequests post throws the following error from time to time.

OSError: [Errno 5] EIO

Does it also require a pull-up resistor? d=dht.DHT22(machine.Pin(4)) Also as a side question, I have an AM2315 hooked up to my esp32 an...

Hi, I noticed very weird behavior when migrating from the ESP8266 to ESP32. when running the following to connect to WIFI: [code]wlan_sta.connect(ssid, password)[/code] When inputting incorrect password credential, the ESP32 will keep trying to auto connect and will continue to throw the following: ...

As the subject states: Does ESP32 restart automatically after an exception is thrown like ESP8266?

I have looked around and I'm not sure why I cannot find an answer for this.


Thank you in advance.
