Adds support for advertising and connections with coded/2M PHY's.
Adds new classes `NimBLEExtAdvertising` and `NimBLEExtAdvertisement`.
When extended advertising is enabled the original advertising classes become unavailable and the new classes must be used.
Changed some return values for advertising methods for consistency with the new classes methods.
* 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.
* Stores complete advertisement payload and only performs parsing on demand. The advertised data is no longer parsed automatically as it is discovered, instead it will be parsed to find only the data requested by the user application when it makes a call to do so. This saves processing time and approximately 2.4k in flash size, with the new methods listed below included.
Add more advertised device field methods:
* Adds haveAdvInterval/getAdvInterval - checks if the interval is advertised / gets the advertisement interval value.
* Adds haveConnParams/getMinInterval/getMaxInterval - checks if the parameters are advertised / get min value / get max value.
* Adds haveURI/getURI - checks if a URI is advertised / gets the URI data.
* Adds haveTargetAddress/getTargetAddressCount/getTargetAddress(index) - checks if a target address is present / gets a count of the addresses targeted / gets the address of the target at index.
* Add support for getting multiple services data from advertisments.
* Adds new methods for getting advertised service data and UUIDS.
- getServiceData(index), gets the service data by index value.
- getServiceData(NimBLEUUID), gets the service data by UUID.
- getServiceDataCount(), gets the number of services with data advertised.
* Templates added for getServiceData(index) and getServiceData(NimBLEUUID)
to be able to specify the data type returned by these methods
Example:
getServiceData<uint32_t>(NimBLEUUID("ABCD");
* Also added:
- getServiceUUID(index), gets the advertised service UUID by index value.
- getServiceUUIDCount(), gets the number of advertised services.
Also adds:
* NimBLEScan::setDuplicateFilter() to tell the controller to filter duplicates
before sending the result to the host.
* NimBLEScan::setLimitedOnly() to tell the controller only report scan results
from devices advertising in limited discovery mode, i.e. directed advertising.
* NimBLEScan::setFilterPolicy() to set the filter policy i.e whitelist only devices.
The value returned by reading a remote characteristic or by getting a notification for it is kept in the class instance of the NimBLERemoteCharacteristic. This value can be accessed as a std::string type using the getValue() function.
This adds templates to read the value in the type used by the peripheral. The same functionality is implemented for getting the manufacturer data or the service data of an advertised device.
* Add NimBLERemoteCharacteristic::getValue(time_t *timestamp = nullptr) to get the latest remote characteristic and (optionally) it's timestamp.
* Added a timestamp to NimBLEAdvertisedDevice for the moment a device was scanned
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.
