* Sets macros to allow compiling when Central role is enabled and Observer disabled, or Peripheral enabled and Broadcaster disabled.
* Adds a macro definition for CONFIG_NIMBLE_CPP_IDF to enable different include paths/functionality for IDF / Arduino.
If a connection event was sent but failed to establish then the disconnect
callback would be triggered when the application was not yet informed of the connection.
* Cleanup logs and add comments.
* Handle the return codes from ble_gap_connect to take proper actions for different codes.
* Improve client event handling to accomodate delayed PDU responses.
* Use connection ID as a replacement for the isConnected flag. Also check if a task is waiting for
results instead of the waitingToConnect flag.
* Adds a disconnect timer so that calling disconnect will start a timer for the connection
supervision timeout time + a small delay. When this expires it will reset the host if a disconnect event
does not occur in this time. This is added as a workaround for the occasional situation
when the controller does not send an event after the disconnect command.
* The type is available in the NimBLEAddress parameter, no longer needed separately.

* Replace all semaphores with task notifications.
* use critical sections to prevent concurrent data access.
* Ensure scan stop has been called before connecting.
* Optimize and cleanup
* Add template casting to NimBLERemoteDescriptor::readValue()
* Removed storage of the descriptor value read as it did not serve any purpose.
* Make remote attribute delete functions public.
* Rename clear...() functions to delete...(), with ... equals Service(-s), Characteristic(-s) or Descriptor(-s), depending on what the function actually deletes
Instead of discovering the peripheral database on connection and consuming
the associated resources this will give the user more control over the
discovery operation.
* Adds void NimBLEClient::discoverAtrributes() for the user to discover all
the peripheral attributes as a replacement for the former functionality.
* getServices(), getCharacteristics(), getDescriptors() now take an
optional bool parameter (default false).
If true it will clear the respective vector and retrieve all the respective
attributes from the peripheral. If false it will retrieve the attributes
only if the vector is empty, otherwise the vector is returned with the
currently stored attributes.
* getService(NimBLEUUID), getCharacteristic(NimBLEUUID), getDescriptor(NimBLEUUID)
will now check the respective vectors for the attribute object and, if not
found, will retrieve (only) the specified attribute from the peripheral.
Add iterators for NimBLEScan: NimBLEadvertisedDevice, NimBLEClient: NimBLERemoteService, NimBLERemoteService: NimBLERemoteCharacteristic and NimBLERemoteCharacteristic: NimBLERemoteDescriptor
This is handy e.g. for showing every address of the advertised devices from a scan. To do so, first get a new scan and next:
```
for(auto pAdvertisedDevice: pBLEScan->getResults()) {
Serial.printf("Address is %s\n", std::string(pAdvertisedDevice->getAddress()).c_str());
}
```
Of course any other property of the advertised device can be shown (or looked up, if that is your use case)
Also this is handy e.g. for showing every UUID in a peripheral. To do so, first connect to a peripheral and next:
```
for(auto pService: *pClient) {
Serial.printf("Service UUID is %s\n", std::string(pService->getUUID()).c_str());
for(auto pCharacteristic: *pService) {
Serial.printf("Characteristic UUID is %s\n", std::string(pCharacteristic->getUUID()).c_str());
for(auto pDescriptor: *pCharacteristic) {
Serial.printf("Descriptor UUID is %s\n", std::string(pDescriptor->getUUID()).c_str());
}
}
}
```
Again of course any other property can be shown, or looked up.
* Exchange map for vector, saving 1,076 bytes of program memory and 5,024 bytes of heap for a small device (LYWSD03MMC)
* Removing m_characteristicMapByHandle (using the handles form m_characteristicVector instead) saving in total (compared to the current master) 1,508 bytes of program memory and 6,500 bytes of heap for a small device (LYWSD03MMC)
* Change NimBLEScan container from std::map to std::vector
* Add function to get advertised device by address
* Update documentation
This allows NimBLE options in menuconfig to reduce code size based on
the roles selected (scan/advertising/central/peripheral).
Significant code space can be saved by removing unnecessary roles for the application.
