====== Gateway ======

==== Version 2.0.1 (Release ID: 61) ====

=== Bugs fixed ===

  * An issue with offline measurements was corrected.
  * Little overlap of clock drift corrected data corrected.

==== Version 2.0.0 (Release ID: 60) ====

=== What's new? ===

  * Automatic clock drift correction for PPG, ACC and ECG data for better data precision during long recordings
  * New data files are now created depending on byte size, recording length and if the software version of the sensor / Gateway changes. Previously a new data file was created for each day.
  * Polar H10 accelleration data is now also recorded.
  * c-med° alpha contact thermometer data is also recorded in addition to the default infrared thermometer data.

=== Bugs fixed ===

  * Improved stability

==== Version 1.6.3 (Release ID: 53) ====

=== What's new? ===

  * It is now possible to stop an ongoing recording by sending a trigger of 0 seconds (via webinterface or via API).
  * An ongoing recording is continued if the Gateway experiences any issues or is rebooted during the recording.
  * Internal improvements.

=== Bugs fixed ===

  * In some occasions the green LED was blinking but the Gateway was not recording any data.

==== Version 1.5.1 (Release ID: 44) ====

=== Bugs fixed: ===

  * Some minor bugs fixed

=== What's new? ===

  * Internal changes

==== Version 1.4.3 (Release ID: 37) ====

=== Bugs fixed: ===

  * date_time_end of a data file corrected (timezone issue).
  * Netto-duration of a data file (duration without recording gaps) corrected.
  * A bug that could make the Gateway crash unexpectedly.


=== What's new? ===


  * Sensor errors are now reported to the server and displayed in different places of the web interface (e.g. if the PPG Signal is too low due to a defect):
    - The serial number of the sensor in the dash view will turn red (you may click on it to go directly to the sensor's detailed view).
    - In the sensor' detailed view, all found errors for this sensor are listed.
    - In the device overview, all devices with errors are marked with a red indicator.
    * Please note that in some occasions the sensor may still be functioning correctly when the error is reported but it might be a loose contact in an initial stage. In that case please have an eye on the sensor if its condition is worsening.
  * Server: “HELP” link in the navigation bar now leads to public wiki page.



==== Version 1.4.2 (Release ID: 36) ====

=== Bugs fixed: ===

  * Data upload bug of Gateway. If connected, the Gateway will upload all data previously available - independent of the currently assigned person.
  * Restarting loop of Gateway.

=== What's new? ===

== Supported sensor devices ==

  * c-med° alpha.

== Supported reference devices ==

  * Polar H10 chest strap (ECG Signal). 

== Data recording ==

  * Live data (feature on request). //Known Issue: Sometimes no data is sent, especially when recording two sensors simultaneously.// 
  * Acceleration data. //Please note: Sometimes acceleration data is sent patchy and time-delayed, causing a shift between PPG and ACC data especially during long recordings. Newest sensor firmware required (°Two 3.0.0, c-med° alpha upcoming).
//

== Configuration ==
  * Enable WiFi for the Gateway. Technical Guide: [[public:enable_wifi|here]].
  * Modified advertising packets. More information available under: Select Device > advertising info.
  - power_behaviour
  - Bluetooth_behaviour

== Special Notes ==
  * The c-med° alpha and the °Two shall no longer be used in [[public:two_configuration_info|Standard Mode]] with the Gateway if the sensor firmware is higher than 2.0.2.
