Removes the response parameter from remote characterisitc subscrible/unsubscribe functions
as a response is always required for this operation as per BLE specs.
Removes the deprecated functions from remote characteristic/desriptor.
* Update examples/docs.
This is a specialized container class to hold BLE attribute values.
- Removes the use of std::string previously used to store the values.
- Allows for setting/getting/notifying values from std::string, std::vector<uint8_t>, Arduino String, const char*, and uint8_t buffers.
- Has operators retrieve the value as std::string, Arduino String, std::vector<uint8_t>, uint8_t* or char pointers.
- Includes iterators and subscript/random access operator.
- Introduces a max length parameter to the creation of server characteristics/descriptors to limit the size of the memory footprint.
- Nearly Seamless integration with existing code.
- Adds a config option to enable/disable timestamp storage when the value is updated.
- Adds a config option to specify the initial size of the value container if not specified in the constructor.
This causes task blocking to fail in client operations leading to exceptions and crashing.
This is a workaround for this situation and will need to be reworked properly in the future.
* 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.
* 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.
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.
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.
