Better allocate the buffer for f_mkfs from the heap otherwise the stack requirement of this library is huge due to a work buffer allocated for f_mkfs in sdcard_mount. The work buffer is only needed if argument format_if_empty is set true (which is by default false). This change is quite important if you plan to use this library in a task. as now it increased the tasks stacks size by 4k, even this memory is never used if users are not aware of the large stack requirement during init this library may have other variables on stack that would have written memory outsides its range which can cause various side effects.

ESP32 Libraries
arduino-esp32 includes libraries for Arduino compatibility along with some object wrappers around hardware specific devices. Examples are included in the examples folder under each library folder. The ESP32 includes additional examples which need no special drivers.
ArduinoOTA
Over The Air firmware update daemon. Use espota.py to upload to the device.
AsyncUDP
Asynchronous task driven UDP datagram client/server
BLE
Bluetooth Low Energy v4.2 client/server framework
BluetoothSerial
Serial to Bluetooth redirection server
Note: This library depends on Bluetooth Classic which is only available for ESP32
(Bluetoothserial is not available for ESP32-S2, ESP32-C3, ESP32-S3).
