* fix: #200 Use `data()`/`size()` instead of `c_str()`/`length()`
* Reduce duplication, only allow template function in characteristic and remote value attr if the type is not a pointer (otherwise sizeof is useless). add appropriate notes
* clean up AttValue::setValue to remove unnecessary length parameter enabling requirement of non-pointer type
The connection handle was not initialized correctly when recording the subscibe status causing the call to send notification/indications to fail with BLE_HS_ENOTCONN.
Refactor attributes to reduce code duplication and improve maintainability.
* Add attribute base classes to provide common code.
* Add const where possible to functions and parameters.
* `NimBLECharacteristic::notify` no longer takes a `bool is_notification` parameter, instead `indicate()` should be called to send indications.
* `NimBLECharacteristic::indicate` now takes the same parameters as `notify`.
* `NimBLECharacteristicCallbacks` and `NimBLEDescriptorCallbacks` methods now take `const NimBLEConnInfo&` instead of non-const.
* `NimBLECharacteristic::onNotify` callback removed as unnecessary, the library does not call notify without app input.
* `NimBLERemoteCharacteristic::getRemoteService` now returns a `const NimBLERemoteService*` instead of non-const.
* Add NimBLEUUID constructor that takes a reference to `ble_uuid_any_t`.
* `NimBLERemoteService::getCharacteristics` now returns a `const std::vector<NimBLERemoteCharacteristic*>&` instead of non-const `std::vector<NimBLERemoteCharacteristic*>*`
* `NimBLERemoteService::getValue` now returns `NimBLEAttValue` instead of `std::string`
* `NimBLEService::getCharacteristics` now returns a `const std::vector<NimBLECharacteristic*>&` instead of a copy of std::vector<NimBLECharacteristic *>.
* Remove const requirement for NimBLEConnInfo parameter in callbacks.
Const is unnecessary as the data can't be changed by application code.
* Change NimBLERemoteCharacteristic::getRemoteService to return const pointer.
* msbFirst parameter has been removed from constructor as it was unnecessary,
caller should reverse the data first or call the new `reverseByteOrder` method after.
* `getNative` method replaced with `getBase` which returns a read-only pointer to the UUID size underlying.
* Added `reverseByteOrder` method, this will reverse the bytes of the UUID, which can be useful for advertising/logging.
* Added `getValue` method, which returns a read-only `uint8_t` pointer to the UUID value.
* Removed `m_valueSet` member variable, `bitSize()` can be used as a replacement.
* General code cleanup.
* Add length parameter to `setValue()` templates, with defaults for backward compatibility.
* Changed `setValue(const char*)` to add an optional length parameter so that a NULL character can be included, defaults to strlen.
* Moved non-inline functions to `NimBLEAttValue.cpp` file.
* Corrected includes to permit compilation as a stand-alone utility.
* Removed repeated code in `setValue()` by using `append()` after clearing the value.
* General code cleanup.
* Construct the device with the parameters from the advertisement in the initialization list.
* Removed no longer needed methods; setAddress, setAdvType, setRSSI, setSetId, setPrimaryPhy, setSecondaryPhy, setPeriodicInterval.
* Removed `hasRSSI()` method, the RSSI is always reported so this is redundant.
* Replace setPayload with new method; `update` which will update the device info when new advertisement data is received.
* getPayload now returns `const std::vector<uint8_t>` instead of a pointer to internal memory.
* Added `begin` and `end` read-only iterators for convienience and use in range loops.
* Timestamp removed, if needed then the app should track the time in the callback.
* Consolidate some functions to use getPayloadByType.
* Add optional index parameter to getPayloadByType.
* Change payload indexing to use 0 as the first item.
* Code cleanup and apply const correctness.
This simplifies the NimBLEAddress code by directly using the NimBLE core `ble_addr_t` type to hold the address
and allows using NimBLE core functions and macros to replace code in some methods.
* `getNative()` replaced with `getBase()` and now returns a pointer to `const ble_addr_t` instead of a pointer to the address value.
* Adds `isNrpa()` method to test if an address is random non-resolvable.
* Adds `isStatic()` method to test if an address is random static.
* Adds `isPublic()` method to test if an address is a public address.
* Adds `isNull()` methods to test if an address is NULL.
* Adds `getValue()` method which returns a read-only pointer to the address value.
* Adds `reverseByteOrder()` method which will reverse the byte order of the address value.
* `equals()` method and == operator will now also test if the address types are the same.
* Code cleanup.
* Replaces the use of std::list with a fixed array to track and manage created client instances.
* Removes: NimBLEDevice::getClientList
* Replaces: NimBLEDevice::getClientListSize with NimBLEDevice::getCreatedClientCount
Replaces all use of NIMBLE_LOGC with NIMBLE_LOGE and redefines NIMBLE_LOGC to use printf.
This allows NIMBLE_CPP_DEBUG_ASSERT messages to print event when log level filtering is set to none.
* Adds the NIMBLE_CPP_DEBUG_ASSERT macro that calls a weak function to allow user defined action, defaults to critical error message and aborts.
* Adds a config option to disable asserts using the NIMBLE_CPP_DEBUG_ASSERT macro.
* Adds a new method, getPeerName to NimBLEServer to read the name from the peers device name characteristic.
* Adds a setting to automatically get the name of the peer when connected and provide it as an additional parameter in the onConnect callback.
* Adds callback with client name after authentication as it may change.
iOS devices specifically expect to receive the ID key of the bonded device even when RPA is not used.
This sets the default value of the key distribution config to provide the ID key as well as the encryption key.
* NimBLEConnInfo - Note that the connection handle is the same as the connection id in the comment for getConnHandle()
* NimBLEServer - int disconnect(const NimBLEConnInfo&) helper method
* Make NimBLEConnInfo functions const.
* Update callback functions and update client to use new functions.
* Update examples.
* Update migration guide.
