Updates the interface to use a typedef'd std::function for the advertise callback, which is backwards compatible but also allows std::bind and lambda functions.
Changes all functions that accept a time parameter to use milliseconds instead of seconds.
* Adds duration input to NimBLEDevice::startAdvertising and NimBLEServer::startAdvertising.
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.
This prevents an exception when initializing a NimBLEAdvertising instance before calling NimBLEDevice::init().
The constructor calls reset() which calls stop(), if the stack was not yet initialized it will cause an exception.
Previous to this NimBLEAdvertising did not have some functionality that was in NimBLEAdvertisementData.
Also NimBLEAdvertisementData was missing functionality that exists in NimBLEAdvertising.
This resolves that by adding the missing functions to both classes.
Changed:
NimBLEAdvertising: Transmission power is no longer advertised by default and can be added to the advertisement by calling ::addTxPower()
Added:
- NimBLEAdvertising::setName
- NimBLEAdvertising::setManufacturerData
- NimBLEAdvertising::setURI
- NimBLEAdvertising::setServiceData
- NimBLEAdvertising::addTxPower
- NimBLEAdvertising::reset
- NimBLEAdvertisementData::addTxPower
- NimBLEAdvertisementData::setPreferredParams
- NimBLEAdvertisementData::setURI
Adds:
- setPartialServices16
- setPartialServices32
- setCompleteServices16
- setCompleteServices32
Each takes an input parameter of std::vector<NimBLEUUID> to allow for advertising multiple services with a simple interface.
Advertising start did not return a value to indicate success/failure,
this patch adds that functionality. In addition, more verbose logging of errors from
this function are provided with the removal of the related asserts.
* Minor code cleanup
m_duration member variable was not set previously which could trigger advertising to start if the
host was reset prior to the application calling start.
Previously when the host reset while scanning (if active prior) it would be restarted automatically.
This caused errors for some applications and has been removed since the event invokes the scan
ended callback for the app to take action. Instead scanning will now only be restarted if the duration
was indefinite and a callback was set for the advertisment events, this use case is less likely to have
a scan ended callback.
Advertising (if active prior) would be started without regard to it's previous state.
This has been corrected to only start advertising again if it was advertising for an idefinite time.
* Adds functionality to advertise for a set duration, similar to NimBLEScan::start.
The first parameter being the duration (in seconds).
The second parameter is a pointer to a callback function that is invoked when advertising stops.
* NimBLEAdvertising::isAdvertising method added, returns true if advertising is currently active.
* These methods were noop's and are now removed due to lack of usefulness and advertisment space consumed if used.
Applications can still manually set these values if desired using NimBLEAdvertisementData::addData.
* Get service handles on server start
* remove service + indicate service changed
* Reset gatt services when no connections active and services changed.
* NimBLEServer::createService can now be used any time and will send service changed
indication if server was already active.
* Add ability to remove advertised serviceUUIDS
* Adds addService() method to server to be allow user to re-add a service previously removed
* Add destructior to NimBLEServer, NimBLEService and NimBLECharacteristic to release allocated resources.
* Use critical sections to access characteristic/descriptor value data.
* Remove unnecessary code
* Create characteristic semaphore only if needed for indications.
* Fix advertising when not broadcasting a service.
Previously we used createServer() to get a reference to the server instance.
This was problematic when using advertising only as it would create a server
when starting advertising. This prevents that and provides better semantics.
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.
