- SensorLog Remote client supports incoming JSON requests:
{"request":"status"}
{"request":"startLogging"}
{"request":"stopLogging"}
{"request":"startSendingSensorData"}
{"request":"stopSendingSensorData"}
{"request":"setDataLabel", "label":0..5}
- SensorLog Remote server supports incoming JSON requests:
{"request":"status"}
{"request":"startLogging"}
{"request":"stopLogging"}
{"request":"setDataLabel", "label":0..5}
{"request":"startLoggingAllConnectedClients"}
{"request":"stopLoggingAllConnectedClients"}
{"request":"loadConfiguration", "url":"URL_SENSORLOG_CONFIG_FILE"}
{"request":"setDataLabelAllConnectedClients", "label":0..5}
- SensorLogRemote server can now be started with dedicated server port
- Beta status: Support for connecting at most one external Bluetooth sensor/device to log its data into a separate log file or to merge its data with the builtin sensors' log file/stream/http. Please note this is still in a beta status.
- added configuration option to "auto set initial attitude reference" before starting to log data.
- added support to start SensorLog with a specific configuration via custom app link by using the link SensorLog://configure/?urlConfigurationServer=URL. You can set the URL and it will automatically fetch the JSON configuration file from the server.
Watch:
- Unfortunately had to remove tcp/ip streaming and Remote Sensorlog feature, due to changes in the low level networking functions of watchOS.
- SensorLog configuration files. Support for saving, and loading SensorLog configuration files. Downloading of configuration settings from Web server via HTTP.
- added configuration option to "auto set initial attitude reference" before starting to log data.
- added HealthKit Export of envAudioExposure data

iPhone and iPad
- SensorLog Remote server and client: You can now connect your iPhone and iPad (as a SensorLog Remote client) with a SensorLog App running as SensorLog Remote server. From your SensorLog App running as SensorLog remote server you can start and stop logging on the connected SensorLog Remote clients.
- Visualize sensor data of connected SensorLog Remote clients on your SensorLog remote server
- Landscape mode for iPad
- Streaming in server mode now allows multiple clients to connect to SensorLog (before only one client connection was possible)
- App operation in the background is not supported on iPhone and iPad anymore, according to Apple’s background operation guidelines.
- "Lock Screen" feature to keep app in foreground for long term logging and streaming
- added feature to share all files at once as zip archive
- Siri and Shortcut Support: SensorLog recording (logging) can now be started via Siri or Shortcuts. Therefore define your shortcuts via Apple's shortcuts app and use Siri to stop and start recording / logging.
- CLLocation speedAccuracy and courseAccuracy data added to log data
Watch:
- HealthKit / Store data export as csv and JSON format
- SensorLog Remote client mode: Connect your Watch (or multiple watches) as SensorLog Remote client with your iPhone or iPad running a SensorLog Remote server. From your iPhone or iPad you can start and stop logging on your connected watches.
- SensorLog Remote client mode: Send sensor data to iPhone or iPad SensorLog remote server to be visualized.
- added feature to send all log files at once to iPhone
- Siri and Shortcut support: Setup the shortcuts on your coupled iPhone and set the details of your shortcut (defined via Apple's shortcut app) so that it is also shown on the apple watch. Siri on your Watch then recognizes the shortcut command and starts "log to file" on your Apple Watch.
- CLLocation speedAccuracy and courseAccuracy data added to log data
