"Guru Meditation Error: Core 1 panic'ed (InstrFetchProhibited)" error
Posted: Fri Jun 22, 2018 4:03 am
Hi,
I tried to connect to IoT platform from ESP32 through MQTT.
My code as below. There is no problem when I use Adafruit MQTT broker.
But I got a "Guru Meditation Error: Core 1 panic'ed (InstrFetchProhibited)" error when tried to send MQTT to this IoT platform.
Is it due to the key is too long? Is there any solution?
