v1.4.0

Fixed

• Fixed missing data from long notification values.
• Fixed NimbleCharacteristicCallbacks::onRead not being called when a non-long read command is received.
• Prevent a potential crash when retrieving characteristics from a service if the result was successful but no characteristics found.
• logs/typos.

Changed

• AD flags are no longer set in the advertisements of non-connectable beacons, freeing up 3 bytes of advertisement room.
• Save resources when retrieving descriptors if the characteristic handle is the same as the end handle (no descriptors).
• Subscribing to characteristic notifications/indications will now always use write with response, as per BLE specifications.
• NimBLEClient::discoverAttributes now returns a bool value to indicate success/failure.
• Scan result callbacks are no longer called when the scan response data is updated in order to reduce duplicates.

Added

• Preliminary support for non-esp devices, NRF51 and NRF52 devices supported with n-able arduino core
• Alias added for NimBLEServerCallbacks::onMTUChange to onMtuChanged in order to support porting code from original library.
• NimBLEAttValue Class added to reduce and control RAM footprint of characteristic/descriptor values and support conversions from Arduino Strings and many other data types.
• Bluetooth 5 extended advertising support for capable devices. CODED Phy, 2M Phy, extended advertising data, and multi-advertising are supported, periodic advertising will be implemented in the future.
