Real DNS resolving timeout used by lwip library is 14[s] (7[s] for DNS1 + 7[s] for DNS2). Function WiFiGenericClass::hostByName() has timeout set to lower value (only 4[s]), so callback function may be called after this low timeout and it may overlappe stack memory used now by other function.
Fixes#3722
They are all broadly similar, all being based on the ESP32-D0WD core, but have
some subtle differences between variants around PSRAM inclusion and camera pin
mappings.
The ESP32CAM "unit" product (SKU: U007) has no PSRAM and maps the
"Pixel Data 0" (Y2 GPIO/OV2640 D2) camera pin to IO17 rather than IO32 as is
the case with most other M5Stack ESP32 camera devices.
The ESP32CAM also requires the "hmirror" and "vflip" camera configuration
bits setting in order to capture a true image.
The relevant M5Stack pin configuration documentation can be found here:
https://docs.m5stack.com/#/en/unit/esp32cam?id=pinmap
According to ESP-IDF API
dc14d027ce/docs/en/api-reference/peripherals/sdmmc_host.rst :
"To configure the bus width, set the width field of :cpp:class:`sdmmc_slot_config_t`. For example, to set 1-line mode:
sdmmc_slot_config_t slot = SDMMC_SLOT_CONFIG_DEFAULT();
slot.width = 1;

1. WiFiProv.ino sketch is added that allows arduino users to do provisioning via SoftAP or BLE. WiFi.beginProvision( ) API is designed for provisioning in Arduino.
2. In WiFiProv.h provisioning class is defined.
3. WiFiProv.cpp contains implementation for provisioning class.
4. README.md file is added which contains detail information for working.
The boundary delimiter (_STREAM_BOUNDARY) needs to be send before the
body part (_STREAM_PART) too follow RFC2046. This caused ffplay/ffmpeg
to fail to open the MJPEG stream.
* std::shared_ptr Memory Leak
clientSocketHande and _rxBuffer are std::shared_ptr, the stop() call was not correctly releasing them and the operator= had similar problems fix for #3679
* operator= second attempt
* operator= third time
WiFiClient.connected() was hanging thinking there was still a connection when the remote had already closed. The one-liner in this patch addresses recv() returning 0 and errno==128. I couldn't find the corresponding errno for 128 but its caught by the case statement which includes EPIPE, ENOTCONN, ECONNRESET and ECONNABORTED so I assume its one of those. Broken pipe maybe?
```c
[D][WiFiClient.cpp:511] connected(): Disconnected: RES: 0, ERR: 128
```
EDIT: added comment to reflect that recv() can set errno when it returns 0.
* Fix flush
flush should not flush the read buffer, it should wait till all output is drained from the write buffer.
* Update BluetoothSerial.cpp
Co-authored-by: Me No Dev <me-no-dev@users.noreply.github.com>
fixed the connected() function so that it only checks errno if recv returns a value of -1.
"in the even of an error, errno is set to indicate the error" --manpage
This fixes the ESP32 Webserver when dealing with a modern webserver with a slow SD card.
* Updated BLERemoteCharacteristic to exposre esp_gatt_auth_req_t parameter for readValue and writeValue.
* Updated BLERemoteCharacteristic/Descriptor to expose a setAuth method to allow tweaking the authentication request type for that remotecharacteristic/descriptor without the need to add auth on each read/write.
If two headers with overlapping names are added while replace == true, like in:
```cpp
http.addHeader("api_token", "pMXFOLpinQqajaRQJYMeWObg2XYmcX1");
http.addHeader("token", "1234");
```
then replacing went wrong. This is fixed with this PR.
This event name was missing in the list:
d5e2bb12ca/tools/sdk/include/esp32/esp_event_legacy.h (L43)
E.g., it was giving
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_GOT_IP
When it should have been
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_DISCONNECTED
Especially if the user wants to use the library as component in IDF,
there are some pitfalls while doing make menuconfig. One is this missing
dependency which will now fail with a better error message with a hint to
the user how to fix it.

This changes all SPI functions that take data pointers which are
not modified so that the declaration is const. This allows them
to be used with const data (i.e. held in flash). No functional
changes are required.
The defnitions of spiWrite() and spiTransferBytes() in
esp-hal-spi.h/c have been updated to be consistent.
Tests:
- Build a simple sketch using SPI.writePattern() and
SPI.transferBytes() which uses const data and verify that the
attached device functions as expected.
I compiled the sample "WebServer -> HttpAdvancedAuth". But the right username and password can not login in. I found the file "Webserver.h" may be have some problem. So I fix it. Please check it.

Pretty sure this was a typo as the deinit doesn't actually allow for reinit if that is an ifndef. Changed in my local copy and can now deinit and reinit just fine. Also, not sure why we are checking for the architecture here. Just curious.

Closes https://github.com/espressif/arduino-esp32/issues/2921
* Added convert method to transfer data from partition to nvs
* Could have sworn I changed the return when I made the label
* Empty state should be 0xFF. Fixed some logging levels
* Set result on success
* Fix semaphores in IDF & std::string assert
Fixes the problem of giving a mutex from a callback with the latest IDF. Also addresses an occasional assert that happens when the btc_task callback gives the semaphore and causes an assert due to both cores potentially writing m_owner concurrently.
* Restored m_owner position in wait() as requested
* Reapply assert fix and move setting m_owner in ::give()
Revert previous revert commit and move setting of m_owner in ::give to before giving the semaphore to prevent race condition possibility.
Implemented the ability to change the ESP32s BLE device address as
according the the BLE specification. This address is used when
advertising the ESP32 over BLE.
* Converted EEPROM library to use nvs instead of partition. Removed eeprom partition from all partition table CSV files.
* Changed variable names, added some comments, formatting as per me-no-dev's requests
* Checks for memory on malloc
* Moved include nvs.h from header to code
* Reworked the extra example to make it more clear how to actually use the library and persist data
* Replaced ARDUINO_VARIANT with const char
* Fixed missing return value
* Added quotes around defined value in macro (Issue #2193)
* Change logging from Error to Verbose when not found and default available
* Move Enter and Exit logging to Verbose Level
* Refactored LOG_X() into log_x()
* Properly allocate string and remove warning
The former way generates the following warning:
ISO C++ forbids converting a string constant to 'char*'
This change makes a character array the size of the string with null ending. It's clearer and gets rid of the warning.
* Better way
Since this is technically immutable, the type should reflect this too.
* add opportunity for more than one retry to _uploadReadByte
* an alternative timeout-based method to making _uploadReadByte more resilient
* move timing variables in the correct scope
* implement and use client.getTimeout instead of hard-coded timeout in _uploadReadByte
* add missing return
* some refactoring to address respecting the timeout in a potentially deadlocked connection
* fix spelling in comment
* address review comments; move impl to cpp file for getTimeout, and remove local variable for currentMillis
* remove redundant cast
* need to check for timeout outside the inner while as well
* update WebUpdate example to print something in unexpected callback condition
* update log_e messages per review comments
If _handler is set, pbuf_free is not called. ~AsyncUDPPacket() calls pbuf_free once but only after calling pbuf_ref in it's constructor. The refcount never reaches zero and the memory allocated for pbuf is never released.
* overload Preferences.getBytes similar to nvs so you can get size of the array.
* Cleaner implentation, with a separate function to get length. Added an example
Currently WiFiClient::write is unable to send messages over 25Kb, because of the hard-coded retry limit of 10, that is getting decremented on every successful send. Since we cannot send more than 2*MTU bytes in one go, and have only 10 retries, write() is limited to approximately 25Kb. Technically it is not a bug, as it correctly returns the number of sent bytes and the caller can set up futher retries. But not all libs are aware of this behavior, for example, WebServer is not.
I suggest improving current behavior by resetting retry counter every time we had a successful write, so the limit of 10 retries will apply to Failed writes only, and will not apply to Successful writes. This will allow to write() blobs of arbitrary sizes.

The default SPI bus is VSPI (see libraries/SPI/src/SPI.cpp). This change corrects a misleading comment in a code example which was stating wrongly that HSPI would be the default one.
