[2.0.0] 2024-12-14
Breaking changes

parameter.NimBLEDevice::getClientListSize
replaced withNimBLEDevice::getCreatedClientCount

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.
Changed
-
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 existence 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.
Fixed
-
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 characteristic 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 Arduino 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.
[1.0.2] - 2020-09-13
Changed
-
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 advertising 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.
[1.0.1] - 2020-09-02
Added
- 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.
Changed
- notify_callback typedef is now defined as std::function to enable the use of std::bind to call a class member function.
Fixed
- Fix advertising start delay when first called.
[1.0.0] - 2020-08-22
First stable release.
All the original library functionality is complete and many extras added with full documentation.
