2.4.1 Release Notes

Architecture of Scent Release 2.4.1

You may be wondering what happened to "2.4.0". 2.4.1 is the exact same code and functionally the same as 2.4.0, but due to an internal test, the OTA release version number needed to be incremented, so there is no official "2.4.0" and the following updates are included in what is now officially called 2.4.1

Changed

• New LED functionality

  • The ION continues to have a solid blue light when turned on.

  • The ION device will now have quick successive flashes (of the light blue color) whenever an Odorant Command is processed.

  • If the device is turned on and not actively recieving odorant commands, The user can check the battery status using a quick press (quick push and release, no hold) on the power button. The device will flash green, orange, red for the battery level from high to low, respectively:

    • GREEN LED = 66% or greater battery life remaining

    • ORANGE LED = Between 34% and 66% battery life remaining

    • RED LED = 33% or less of battery life remaining

    • NOTE: Odorant Commands will supersede the batter checking functionality. Battery level checking is not possible while the device is actively receiving odorant commands.

• The device will briefly flash red when turning the device off (after a 3-second push and hold).

• The 2.4.1 release also includes the 2.3.0 updates previously not available via the external OTA release process. For convenience those improvements are repeated here:

  • Added functionality to allow an app to refresh cartridge information when cartridges are inserted while the ION is currently connected to an App such as the ION Admin App. While using the ION Admin app a user can hit the refresh button after inserting a new cartridge and all the cartridge information will be updated without needing to power cycle the device.

  • OTA error codes will now be interpreted by the app if there is an issue while trying to update the device. These errors will be conveyed via message pop-ups via the app with minor details.

    • WIFI ERROR - this error means the WIFI credentials were incorrect or there was an issue with connecting to the inputted WIFI network (router error, etc.)

    • JSON ERROR - this error means that there was a problem while trying to find the required firmware file. This error can happen if there is a problem with the device parsing the file or an issue with the values stored within the firmware JSON file.

    • OTA ERROR - this error means that there was a problem while performing the actual update. Many things can cause this problem: a connection timeout, a watchdog error, problems with the incoming data stream, problems with the partition, and many other minor issues. The process will be stopped and the app will allow you to try again.

    • FIRMWARE UP TO DATE - this will occur if the currently loaded firmware is already the latest version. An OTA update will not be allowed at that time.
