Summary
The examples demonstrate how to create a WPA2 Enterprise connection, but it requires using various direct esp_idf functions. This patch is intended to create another overloaded version of the WiFi.begin() function that allows a user to create a WPA2 Enterprise connection in much the same way as different kinds of connections.
My only question for the core maintainers is whether I should leave those #ifdef's in there. I added them so that it was easy to disable all the code I added via defines from my platformio.ini file, but they technically aren't necessary.
Impact
This should make it easier for novice users to create WPA2 Enterprise connections. For my university, I didn't need a root certificate or the client certificate or client key, so I haven't been able to debug those scenarios, but I built the begin functions to allow any one of those to be used, if needed.
I can confirm that eduroam-style WPA2 Enterprise networks that only require authentication with a username and password works as expected.
In my project I'm getting the error
```
In file included from lib/Discovery/Discovery.cpp:2:
C:/Users/David/.platformio/packages/framework-arduinoespressif32/libraries/AsyncUDP/src/AsyncUDP.h:47:1: error: expected class-name before '{' token
```
Adding a reference to Stream.h fixes it.
* Added dual antenna for WiFi (based on the ESP32-WROOM-DA module)
* Fixed build error
* Fixed indentation and renamed function to setDualAntennaConfig
* Added the RX and TX selection modes as configuration
* Mode code optimization
Summary
Touch Sensor refactoring to be based on IDF 4.4.
Adds support to ESP32S2 and future ESP32S3.
Adds some new APIs:
For all chips:
void touchAttachInterruptArg(uint8_t pin, void (*userFunc)(void*), void *arg, uint32_t threshold);
This function allows the user to add and pass a void* parameter to the ISR user callback.
void touchDetachInterrupt(uint8_t pin);
This function detaches ISR call back for the touch pad pin.
Only ESP32 chip
void touchInterruptSetThresholdDirection(bool mustbeLower);
This function allows the user to set if the ISR callback will be activated when the touch sensor readings are lower or higher than the threshold defined. See example TouchButton.ino.
Only ESP32-S2 and ESP32-S3 chips
bool touchInterruptGetLastStatus(uint8_t pin);
This function reports if the touch pad pin is touched or untouched. It can be used with ISR to identify when it is touched and untouched (released). See example TouchButtonV2.ino.
Impact
None. ll original APIs and examples now run on ESP32 and ESP32-S2.

The problem was that QNameLength is a signed byte and therefore its not possible to count up to 255. Additionally we need 256 bytes for the QName string to accommodate for the zero termination.
With LittleFS the `fs.exists(path)` returns true also on folders. A `isDirectory()` call is required to set _isFile to false on directories.
This enables serving all files from a folder like : `server->serveStatic("/", LittleFS, "/", cacheHeader.c_str());
File f = fs.open(path);
_isFile = (f && (! f.isDirectory()));
Reliability fix for autoReconnect when assoc_fail, autoReconnect did not work before for these failures.

Summary
This PR is refactoring of SigmaDelta HAL in order to use IDF instead of current Register manipulation approach.
Impact
Change in API:
uint32_t sigmaDeltaSetup(uint8_t channel, uint32_t freq);
changed to -->
uint32_t sigmaDeltaSetup(uint8_t pin, uint8_t channel, uint32_t freq);

Summary
RMT HAL refactoring based on IDF.
Impact
Improves RMT by adding IDF v4.4 support.
Receiving RMT can handle any size of data.
rmtInit() has a new parameter - RxBufferSize - to hold any number of data when receiving RMT.
rmtWrite() has a new parameter - wait_tx_done - to block writing until sending all data.

23 Braille Display Page (0x41)
Braille display allow visually impaired computer users to read out text using raised pins. The pins are electro-mechanically
activated. These devices also have support for controls that help navigate the computer screen. Typically, braille displays
interface with software known as a screen reader in order to perform this navigation.
## Summary
Arduino ```setup()``` and ```loop()``` run under a Task with a fixed Stack size of 8KB.
Users may want to change this size.
This PR adds this possibility by just adding a line of code, as for example:
``` dart
ESP_LOOP_TASK_STACK_SIZE(16384);
void setup() {
}
void loop() {
}
```
## Impact
None. It adds a new functionality to ESP32 Arduino.
If ```ESP_LOOP_TASK_STACK_SIZE(newSize);``` is not declared/used, it will compile the sketch with the default stack size of 8KB.

Current implementation clears _headers when request was sent. If the
user added custom request headers, they will be lost and the redirected
request will not contain them. This commit changes the scope of cleanup
so that the headers survive redirects but don't survive connection
reuse.
1.0.6 changed scanning method to always scan all available channels during connect. This results in results in connect taking about ~3 seconds instead of ~1. This patch changes the behavior to use WIFI_FAST_SCAN if client used a specific channel.
Summary
Only affects ETH (not WiFi)
This PR solves #5733 by allowing the DHCP IDF server to complete its tasks and only then it sets a static IP.
This also solves another related failure reported in this issue (#5733 (comment)).
fix#5733
Impact
Adds a delay in order to wait for DHCP to actually terminate before setting the static IP configuration in ETH.
When using the FTM examples I got an error in the FTM_Initiator.ino:
*"wifi:channel=0 is invalid"*
I solved it for myself by simply passing the channel argument to be 1 in *WiFi.initiateFTM*. However, a better fix would be to directly change the default channel here.
* examples: WiFi and Ethernet examples organization
* examples: Change on CI scripts to include new folder
* Library name reverted to WiFi
* examples: WiFi and Ethernet examples organization in a new folder
* examples: Eth files moved from WiFi to Ethernet lib and CMakeLists updated
The client always appends "Basic" to the authorization header, however there are other auth schemes that can be used: https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication
For example "Bearer" when using OAuth.
This PR adds a `setAuthorizationType` method to the HTTPClient which allows this scheme to be configured by the caller. Authorization type is set to "Basic" by default so this will have no impact on existing usecases.
This adds a function to WiFiClientSecure to set the ALPN protocol.
This is required for an MQTT client to connect to AWS IoT when using an AWS Custom Authorizer, as described here.
Example code snippet:
...
WiFiClientSecure wiFiClient;
// ALPN protocol, needed with AWS custom authorizer
const char *aws_protos[] = {"mqtt", NULL};
void setup() {
wiFiClient.setCACert(AWSCAPEM);
wiFiClient.setAlpnProtocols(aws_protos);
}
...

* SPI.h add new call to return a SS pin number used.
As code example states, the SS pin needs to be explicitly set for output for SPI to work, but the pin number have to be coded in addition to the SPI logic in the library, which means this duplicates code. It is much better to just be able to get the pin number from library itself.
* Update SPI_Multiple_Buses.ino to use new pinSS method
Simplify the example case, to show usage of pinSS method. This also simplifies the example, removing duplicated code.
Summary
New feature: Add the ability to get the peer certificate of an SSL connectio. This is useful for IoT when the root/cert trust chain has a shorter lifecylce than the device itself. Includes example code.
It adds two methods to the WiFiClientSecure client:
bool getFingerprintSHA256( uint8_t fingerprint_remote_sha256[32]) -- return true and the fingerprint (i.e. the SHA256 of the raw x509 as a DER - identical to what you see in for example your webbrowser). Or false on error.
const mbedtls_x509_crt* getPeerCertificate(); -- return the actual X509 struct or NULL on error.
Impact
No impact; backwards compatible (only adds to the API)
When compiling with verbose logging, the build would error with a message saying `len` is not defined in `tud_vendor_rx_cb()`. This change fixes the error.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"
"The class Webserver is declared with two explicit constructors, one with signature:
WebServer::WebServer(IPAddress addr, int port)
Using this results in a server listening on the port number obtained by converting the value of the IPAddress addr argument (in host byte order) to a uint32_t and then to a uint16_t, which is manifestly not the result that would be expected.
...
As for a fix, we can assume from these results that this constructor is not being used and therefore could simply be deleted."

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"
This change adds support for multi-homed servers to libraries/WiFi. It was assumed to be there already by libraries/WebServer, but was not.
This led to unexpected results when the IP address-specific constructor of class WebServer was used (see issue 5507).
This change was tested using three concurrent instances of WebServer, one bound to the WiFi station address, one bound to the WiFi soft AP address,
and one bound to INADDR_ANY. See libraries/WebServer/examples/MultiHomedServers for the test method.
* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result" (cont.)

"for this test to be valid, both servers should be on the same port. That is how you can make sure that the functionality works."
"Using a Core Debug Level of Verbose and the WebServer serveStatic() function with the default value of nullptr for its cache_header argument, results in a LoadProhibited exception in _svfprintf_r().
This is because serveStatic() calls log_v() with cache_header corresponding to a "%s" in its format but without checking that cache_header is not nullptr, and then logv() (indirectly) calls _svfprintf_r().
On the other hand, with a Core Debug Level other than Verbose, this does not occur."
Changed serveStatic() to the check value of cache_header and if it is nullptr, instead pass an empty string to log_v().
* Add initial support for USB MSC
* Add Firmware Upload/Download With MSC
Current running firmware is available as file inside the MSC Disk. To update the firmware on the ESP, just copy a regular firmware bin into the drive
* Support overwriting of the firmware file

## The problem
WiFiClient's connect method variant where no timeout is passed can block esp32 MCU and may then cause watchdog to kick in and reset the device. This behavior is different from that, what is in arduino-esp8266 core.
## Summary
Some cross-esp libraries (working both on esp32 and 8266), like PubSubClient simply call connect method on WiFiClient, to get connected to remote server. However, connect behavior varies betwen esp arduino 8266 and esp arduino 32 cores. This pull request tries introduce same behavior - to make connect method non-blocking on esp32, like it is with 8266 arduino core.
## Proposed solution
Introduce default fixed timeout that can be changed by #define - by default set to 3 seconds.
### Affected components:
WiFiClient
### Affected methods:
```c++
int connect(IPAddress ip, uint16_t port);
int connect(const char *host, uint16_t port);
```
### Impact
May impact projects or libraries using connect method variant without specified timeout, where:
- remote is located far away or
- connection is heavily limited, or
- remote is slow, when it comes to accept the connection
In [HTTPClient](https://github.com/espressif/arduino-esp32/tree/master/libraries/HTTPClient), if the `Transfer-Encoding` header is set to `identity`, an error (Transfer-Encoding not supported) will occur.
HTTPClient will consider the request as `identity` if the `Transfer-Encoding` header is not set. But it is also defined a response with `identity` explicitly set in the `Transfer-Encoding` header (ref:[MDN Web Docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Transfer-Encoding)).
This pull request will allow the request to be processed normally even when `identity` is explicitly set.
lwip lib bundled with esp32 Arduino supports only one ntp server. Any additional servers set are just silently ignored.
This default is different from esp8266 Arduino core and very confusing. Most of the examples provided uses 3 different ntp servers for redundancy while only the first one is used actually.
Addressing issue #4964
Closes#5398
Using the same non-blocking socket connect pattern for respecting connection timeout, copied from WiFiClient::connect.
WiFiClient::connect uses lwip_connect_r, whereas start_ssl_client uses lwip_connect. I haven't found what is the difference between them. I tested both, both work ok, so I kept lwip_connect.

* Update toolchain
* Update package_esp32_index.template.json
* add optional component dependencies after Kconfig options are known (#5404)
Until this commit, Kconfig options (e.g. CONFIG_TINYUSB_ENABLED) were
used in conditions preceding idf_component_register to determine which
components need to be added to `arduino` component requirements.
However the Kconfig options aren't known at the early expansion stage,
when the component CMakeLists.txt files are expanded the first time
and requirements are evaluated. So all the conditions evaluated as if
the options were not set.
This commit changes the logic to only add these components as
dependencies when the Kconfig options are known. Dependencies become
"weak", which means that if one of the components isn't included into
the build for some reason, it is not added as a dependency.
This may happen, for example, if the component is not present in the
`components` directory or is excluded by setting `COMPONENTS` variable
in the project CMakeLists.txt file.
This also ensures that if the component is not present, it will not be
added as a dependency, and this will allow the build to proceed.

Commit d15e1b0e [1] in the 2.0.0 pull request #4996 introduced a filter
to connect only to WiFi networks with a RSSI of -75 or better. This
results in strage behaviour, as a scan still shows networks, that can't
be connected to, even though with older versions, connecting to those
networks was possible and the connection (albeit slow) was stable.
Remove the RSSI filter for now by setting the threshold to -127, i.e.
the lowest possible value. Maybe in the future the filter threshold
could be exposed to users, to allow filtering out nearly unreachable
networks.

When iterating through APlist from first to the last element, a corrected password for already known SSID is not used. Therefore, I propose to iterate from the back of the list. With iterating from the back through the vector, an already known SSID with a corrected password is used instead.
Proposed fix to #4627 as a remediation to PR #3995#3995 introduced that a device detected on BLE would not be entered in vector if a callback has been defined.
By doing so, it was not possible anymore to have a counter in a call back (AND device in vector) to limit the number of detected device in a single scan, which could crash ESP32 as a result.
* add onMtuChanged to BLEServerCallbacks
Add method onMtuChanged to the BLEServerCallbacks so the application can be notified if the MTU size changes.
* Correct missing semicolon and misspelled method.
Correct missing semicolon and misspelled method.
Thi may happen if read() gets called repeatedly (such as in HttpClient to parse response headers) and the connection is closed unexpectedly or the remote peer may have unexpected behavior that causes the underlying socket to report an error. In that case read() itself calls stop(), which invalidates the receive buffer object. Then when read() is called again without checking, such as inside readStringUntil(), the _rxBuffer is null and ESP32 crashes.
Pull request #4999 added setMTU function to BLEClient.cpp/.h, this line provides implementation of this added functionality to the BLE client example to resolve cases in which data from notifyCallback exceeds 20 characters (3 bytes for command type and attribute ID, 20 bytes for attribute data (char*)pData).
Added new BLE5 features to use on C3/S3 family:
extended scan,
extended/multi advertising
New code is not fancy (no feedback from events), but i think it is functional. To get feedback from events i am suggesting to use custom GAP callback, which is already implemented in BLEDevice.
- Use Serial.print instead of log_i for QR code helper information,
so that it is always printed by default.
- Expose the RainMaker factory reset and wifi reset APIs.
- Simplify example to have only a Switch device. Create another example for custom device.
- Enable push button based Factory reset and Wi-Fi reset.
- Added support for the TimeZone service.
- Moved API doc to RainMaker library's top level README.
- Other minor doc changes.
Hey guys,
so I wanted to do a BtClassic Discovery without the need to call connect
and to list all found devices on a display and continue work with that list.
I wasn't capable to test the example code with my file structure, but I did use the discovery already in some different situations.
However when I noted that the Bluedroid stack won't let me enforce an RfComm SPP connection to a GPS Device (Skytraxx 2 plus, I guess its interface is built so simple that it doesn't advertise its SPP over SDP), I will probably have to switch to BtStack (BlueKitchen) and stop on this side meanwhile
The current implementation has a getMTU function which returns the mtu sent in a message.
This function allows you to set the MTU value on the connected device, it first sets the MTU locally by calling esp_ble_gatt_set_local_mtu. It then calls esp_ble_gattc_send_mtu_req to have the connected device also change its MTU size.
This adds support for the KSZ8081 ethernet phy.
Only the IDF 4+ specific code is modified, as the phy support was only
added recently:
