Add sdkconfig option CONFIG_ARDUINO_UDP_TASK_PRIORITY, which sets the task priority for the UDP vtask." (#4131)

Remove device from Peer list if connection fails.

Only call onConnect callback if connection was successful.

Only call onDisconnect callback if the connection was previously connected (ESP_GATTC_DISCONNECT_EVT is fired on a unsuccessful connection attempt also).

Resolves a number of issues with phantom events and callbacks being fired.

::addPeerDevice and ::removePeerDevice are called with m_appId, so should ::updatePeerDevice as all use the same parameter for the underlying map's key.

* Fix for issue #4158: Crash with stack trace originating in Bluedroid
Improved configuration of scan response data in 'BLEAdvertising' avoids the crash:
- Added member variable 'm_scanRespData' to configure scan response differently from advertising data
- Initialization of 'm_scanRespData' in BLEAdvertising constructor
- Use of 'm_scanRespData' within BLEAdvertising::start() to configure the scan response
- 'Flags' and 'Appearance' are cleared in the scan response data
- With this fix, device names of up to 29 characters can be used without causing a crash.

The web server currently lacks the ability to send a buffer. Only strings are supported.

This PR adds an overload to sendContent.

Make options list into a table

Fixes: #3460

This code has been run in production for 1 month and it looks stable, no data dropped and it definitely fixes the issue described. I think that this can be merged to avoid using custom package referencing in PlatformIO that has been used in quite a few projects for now.

Add partition label argument to Update and ArduinoOTA classThe UpdateClass in the Updater component has the ability to update data toa SPIFFS partition. It selects the first available partition using theESP-IDF esp_partition_find_first() function.That behaviour is problematic if one has multiple SPIFFS partitions.This change allows a user to pass the label argument (defaults to NULL)to UpdateClass::begin() so a specific SPIFFS partition can be updated.Additionally, ArduinoOTA can set this partition label using thenew method ArduinoOTAClass::setPartitionLabel which is optional.This change does not break compatibility.

The UpdateClass in the Updater component has the ability to update data to
a SPIFFS partition. It selects the first available partition using the
ESP-IDF esp_partition_find_first() function.
That behaviour is problematic if one has multiple SPIFFS partitions.

This change allows a user to pass the label argument (defaults to NULL)
to UpdateClass::begin() so a specific SPIFFS partition can be updated.

Additionally, ArduinoOTA can set this partition label using the
new method ArduinoOTAClass::setPartitionLabel which is optional.

This change does not break compatibility.

* BLERemoteChar: fix descriptor 2902 write for characteristic notifications

When registering a notification on a characteristic, the 2902 descriptor
(CCCD) value is set to 1 (or 2 for indication).
According to the BLUETOOTH CORE SPECIFICATION Version 5.2, Revision Date
2019-12-31, section 4.12.3 "Write Characteristic Descriptors" (page 1588),
the characteristic descriptor write must expect a response.
Currently, the descriptor write is performed without expecting a reponse,
which prevents the notification to be functional with some BLE stacks.
This commit modify the write to expect the response.

* BLERemoteChar: forward GATT client event to characteristic descriptors

This commits prevents a permanent wait when calling BLERemoteDescriptor
readValue function, on the m_semaphoreReadDescrEvt semaphore.

ESP32 BLE stack calls to remote characteristic
- notification,
- value read
- value write
and remote characteristic descriptor
- value read
are asynchronous.

When such a call is performed by this library, a semaphore is taken prior
to the BLE stack read or write operation, and waited on after it.

Releasing the semaphore is done by the characteristic event handling
function (gattClientEventHandler), when the appropriate event is received.

However, the characteristic descriptor events are discarded, and the
value read semaphore is never released.

This commits forwards the GATT client events from the remote
characteristic down to their remote characteristic descriptor, and
implements their event handling.

Adding a semaphore for the remote characteristic descriptor value write
will be done in a separate commit.

* BLERemoteDescriptor: add semaphore to characteristic descriptor write

This adds a semaphore to characteristic descriptor value write, to mimic
the value read function, and to ensure completion of the operation before
we carry on.

esp8266 --> esp32

fixes: #4472

Fixes issue #4293

Fixes possible issues with assembly files in external libraries

* Corrections of Find, FindUntil and FindMulti

Find has some bug that is not working with Ethernet.find() so, I copied code from Stream.h and Stream.cpp in AVR-CORE library and now it's working perfectly.
I don't know where was the error, but an Ethernet.find compiled to MEGA2560 was working but not working when compiled to esp32, after corrections of code (copy of AVR-Core libraries) it's working perfect.
So probably has some error on original ESP32-Core library.

Below is part of code that was working with MEGA2560 and not with ESP32 libraries.
client.find never return TRUE with ESP32 original library and with AVR it's works.

boolean esp32_fw_update(EthernetClient &client, DecodedHeader &header, const String &field_filename, const String &field_crc) {

  char bound[header.boundary.length()+3];
  char term[]="\r\n";
  
  strcpy(bound,header.boundary.c_str());
  strcat(bound,term);
  while (client.find(bound)) { 
    String line=client.readStringUntil('\r');

* Add an aditional (void *) arg to the RMT callback - to allow more flexible handling of the callback (e.g. by passing a private struct or a class pointer). Same pattern as used by the Ticker() and many others. Example updated & new example with a trapoline added.

* Fix example for new API

* Fix lint warnings

* Add a second missed example.

* Correct timeout & improve socket error handling.

This is in line with the
[arduino platform specification](https://arduino.github.io/arduino-cli/platform-specification/#recipes-for-extraction-of-executable-files-and-other-binary-data)
specifying that the file extension after recipe.objcopy is arbitrary and
that the AVR platform uses `eep` & `hex`, while the esp32 platform seems
to have file extensions `partition.bin` & `bin`

Fix support for following redirects added by ee88c42c (#4240) (#4385)

* fix typos

* made return value description a bit more helpful

* Updated Readme.md

Added links to latest release. Made it look a lot cleaner.

* Update README.md

I met problem while I was working with the WiFiClientSecure.
I tried to found the source of the problem, and I found it in the sll_client.cpp.
Please check my contribution.

I've open this problem in #4335 but received no response.

Please add OpenKB Board Product from INEX Co. Ltd.

I spent quite a while today figuring out how to get an OTA update over HTTPS on a custom port working. A part of my problem was not putting a slash before the .bin filename, since it wasn't there in the example. This produced invalid HTTP requests. Adding the slash would make it clear that it needs to be there.

Given that the URL in line 53 contains the same words "server" and "file.bin", one might assume that in line 55, the slash after the port number would get added automatically, however I have found out that without a slash you get an invalid request. Adding the slash removes any doubt.

Add a new Dev Board S.ODI Ultra v1 in esp32 library

* HttpsOTAUpdate introduced new IDF component requirements.
These have been added to CMakeLists.txt to correct compilation errors when using Cmake.

I was playing with the mDNS service and noticed the method MDNSResponder::addService could return a Boolean with the way it is implemented just like other functions in this library.

This would be handy to know at a higher level weather or not the service was added correctly to the mDNS server of the ESP32.

This is a fix for missing scan responses after a first successfull scan.

While running the BLE_scan.ino sketch with wantDuplicates=false, i got
only one result with correct advertising and scan response length (31,26):

pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks(), false);
pBLEScan->start(scanTime, false);
...
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 31 + 26, addr type: 1

All following calls to start() just returned the advertising data without
scan response data:

pBLEScan->start(scanTime, false);
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 31 + 0, addr type: 1

With "wantDuplicates=true" i got:

pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks(), true);
pBLEScan->start(scanTime, false);
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 31 + 26, addr type: 1
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 31 + 26, addr type: 1
[W][BLEScan.cpp:73] handleGAPEvent(): ESP_GAP_SEARCH_INQ_CMPL_EVT
Devices found: 1
Scan done!
pBLEScan->start(scanTime, false);
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 31 + 0, addr type: 1
[W][BLEScan.cpp:109] handleGAPEvent(): bytes length: 0 + 26, addr type: 1

Explicitly initializing m_scan_params.scan_duplicate of BLEScan solves
this issue (In my case the un-initialized value was
m_scan_params.scan_duplicate == 1073599044).
