Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

[1.4.1] -2024-12-18

  • Fix version of dependency to sensirion-core to >= 0.5.1

[1.4.0] - 2024-12-12

Added

  • Allow to request only the last X samples when doing a data download (implement Requested Samples Characterisitc on Download Service)

Fixed

  • use the last 2 Bytes of Mac Address as Device ID in BLE Advertisment (fixes mismatch of logged id and id appearing in MyAmbience as mentiond in #44)
  • pin version of NimBLE lib to < 2.0.0 as 2.0.0 is not a proper release and breaks writing to BLE Characteristics

Changed

  • increased delay in loop to avoid that data packs are sent too fast during data download

[1.3.2] - 2024-06-19

Fixed

  • Change string import to from <string.h> to
  • Reporting age for latest samples needs to be in milli-seconds

[1.3.1] - 2024-04-17

Fixed

  • Fixed dependency list (Sensirion_UPT_Core was renamed 'Sensirion UPT Core')
  • Added missing include <string.h> in ByteArray.h

[1.3.0] - 2024-03-25

Added

Added

  • Support for Battery BLE Service you can use to indicate the battery level (see Example1_MockedReadings).
  • Battery Level Service
  • PlatformIO support

Changed

  • Extract BLE Configuration into UPT Core Dependency
  • characteristicSetValue and characteristicNotify of IBLELibraryWrapper now return a bool indiciating whether the set/notify was successful
