-
nimconfig.h
(Arduino) is now easier to use. -
NimBLEServer::getServiceByUUID
Now takes an extra parameter of instanceID to support multiple services with the same UUID. -
NimBLEService::getCharacteristic
Now takes an extra parameter of instanceID to support multiple characteristics with the same UUID. -
NimBLEAdvertising
Transmission power is no longer advertised by default and can be added to the advertisement by callingNimBLEAdvertising::addTxPower
-
NimBLEAdvertising
Custom scan response data can now be used without custom advertisment. -
NimBLEScan
Now uses the controller duplicate filter. -
NimBLEAdvertisedDevice
Has been refactored to store the complete advertisement payload and no longer parses the data from each advertisement.
Instead the data will be parsed on-demand when the user application asks for specific data.
NimBLEHIDDevice
Characteristics now use encryption, this resolves an issue with communicating with devices requiring encryption for HID devices.
-
NimBLEDevice::setOwnAddrType
added to enable the use of random and random-resolvable addresses, by asukiaaa -
New examples for securing and authenticating client/server connections, by mblasee.
-
NimBLEAdvertising::SetMinPreferred
andNimBLEAdvertising::SetMinPreferred
re-added. -
Conditional checks added for command line config options in
nimconfig.h
to support custom configuration in platformio. -
NimBLEClient::setValue
Now takes an extra bool parameterresponse
to enable the use of write with response (default = false). -
NimBLEClient::getCharacteristic(uint16_t handle)
Enabling the use of the characteristic handle to be used to find the NimBLERemoteCharacteristic object. -
NimBLEHIDDevice
class added by wakwak-koba. -
NimBLEServerCallbacks::onDisconnect
overloaded callback added to provide a ble_gap_conn_desc parameter for the application
to obtain information about the disconnected client. -
Conditional checks in
nimconfig.h
for command line defined macros to support platformio config settings.
-
NimBLEAdvertising::start
now returns a bool value to indicate success/failure. -
Some asserts were removed in
NimBLEAdvertising::start
and replaced with better return code handling and logging. -
If a host reset event occurs, scanning and advertising will now only be restarted if their previous duration was indefinite.
-
NimBLERemoteCharacteristic::subscribe
andNimBLERemoteCharacteristic::registerForNotify
will now set the callback regardless of the existance of the CCCD and return true unless the descriptor write operation failed. -
Advertising tx power level is now sent in the advertisement packet instead of scan response.
-
NimBLEScan
When the scan ends the scan stopped flag is now set before calling the scan complete callback (if used)
this allows the starting of a new scan from the callback function.
-
Sometimes
NimBLEClient::connect
would hang on the task block if no event arrived to unblock.
A time limit has been added to timeout appropriately. -
When getting descriptors for a characterisic the end handle of the service was used as a proxy for the characteristic end
handle. This would be rejected by some devices and has been changed to use the next characteristic handle as the end when possible. -
An exception could occur when deleting a client instance if a notification arrived while the attribute vectors were being
deleted. A flag has been added to prevent this. -
An exception could occur after a host reset event when the host re-synced if the tasks that were stopped during the event did
not finish processing. A yield has been added after re-syncing to allow tasks to finish before proceeding. -
Occasionally the controller would fail to send a disconnected event causing the client to indicate it is connected
and would be unable to reconnect. A timer has been added to reset the host/controller if it expires. -
Occasionally the call to start scanning would get stuck in a loop on BLE_HS_EBUSY, this loop has been removed.
-
16bit and 32bit UUID's in some cases were not discovered or compared correctly if the device
advertised them as 16/32bit but resolved them to 128bits. Both are now checked. -
FreeRTOS
compile errors resolved in latest Ardruino core and IDF v3.3. -
Multiple instances of
time()
called inside critical sections caused sporadic crashes, these have been moved out of critical regions. -
Advertisement type now correctly set when using non-connectable (advertiser only) mode.
-
Advertising payload length correction, now accounts for appearance.
-
(Arduino) Ensure controller mode is set to BLE Only.
-
NimBLEAdvertising::start
Now takes 2 optional parameters, the first is the duration to advertise for (in seconds), the second is a
callback that is invoked when advertsing ends and takes a pointer to aNimBLEAdvertising
object (similar to theNimBLEScan::start
API). -
(Arduino) Maximum BLE connections can now be altered by only changing the value of
CONFIG_BT_NIMBLE_MAX_CONNECTIONS
innimconfig.h
. Any changes to the controller max connection settings insdkconfig.h
will now have no effect when using this library. -
(Arduino) Revert the previous change to fix the advertising start delay. Instead a replacement fix that routes all BLE controller commands from
a task running on core 0 (same as the controller) has been implemented. This improves response times and reliability for all BLE functions.
- Empty
NimBLEAddress
constructor:NimBLEAddress()
produces an address of 00:00:00:00:00:00 type 0. - Documentation of the difference of NimBLEAddress::getNative vs the original bluedroid library.
- notify_callback typedef is now defined as std::function to enable the use of std::bind to call a class member function.
- Fix advertising start delay when first called.
First stable release.
All the original library functionality is complete and many extras added with full documentation.
