I've tried running an old application of mine on an ESP32 micro controller and I kept getting errors such as
rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
or
CORRUPT HEAP: Bad head at 0x3ffd8c18. Expected 0xabba1234 got 0xbaad5678
or
Guru Meditation Error: Core 1 panic'ed (InstrFetchProhibited). Exception was unhandled.
on all of my boards when attempting to use Bluetooth.
Turns out there has been an update in ESP32-Arduino.
Changing
platform = espressif32
to
platform = [email protected]
solved my issue.
