5.3.1
2023-03-15
- bug fixes
iPhone/iPad:
- SensorLog configuration files. Support for saving, and loading SensorLog configuration files. Downloading of configuration settings from Web server via HTTP.
- 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
