2.3.6

Fixed

• NimBLEAdvertisedDevice::isConnectable returning incorrect result.
• Extended advertisements not reporting full data.

Added

• Support up to 1650 bytes of advertisement with extended advertising.

2.3.5

Fixed

• esp32c3/s3 max connections not being properly applied.

2.3.4

Fixed

• NimBLEClientCallbacks::OnConnectFail not called when connection not established.
• Removed invalid reference to refactored original examples in README.md.
• Cleanup redefinition warnings for Arduino core 3.3+.

2.3.3

Fixed

• Multiple definition errors for some functions with esp32c6/h2/c2 with Arduino core 3.3+.

2.3.2

Fixed

• Max connections not being applied correctly above 4.
• Build errors with arduino cores using IDF v4.x
• onConnect callback not being called when the status is BLE_ERR_UNSUPP_REM_FEATURE, workaround for upstream issue.

Changed

• FreeRTOS port uses the old porting layer for all but the latest esp32 mcus.
• By default BLE secure connections is disabled now to reduce issues when it's enabled but not used by the application.
• BLE mesh files are now only compiled if mesh is enabled in the project configuration.
