Firmware version 4.0

Release date: 12 April 2022
  • FUOTA mechanism released
The FUOTA functionality differs from the FUOTA that's being used by the LoRa Alliance. In order to update the firmware version of devices, they should be connected to MClimate's cloud. It takes around 1500 downlinks to perform FUOTA. Due to duty-cycle limitations of the gateways, we recommend staging the FUOTA in smaller batches in case your installation is sizeable.
Feel free to reach out to [email protected] to acquire more details on the process.

Firmware version 3.6

Release date: 12 December 2021
  • Minor bugfixes and updates
    • If pFirstLast or pNext is less than 17 steps, move the motor with 17 steps.
    • If one wants to move the motor with less than 17 steps, move the motor with 17 steps.
  • Preparation for FUOTA mechanism release
Known issues:
  • When device is in operational mode "Automatic with external temperature sensor" and it restarts due to power-off or Communications watch-dog, the device backs off to "Automatic" operational mode.
    • Suggested fix on production: When you send the external temperature measurement to Vicki, always append the command to switch to operational mode "automatic with external temperature sensor" - "0D02"
  • Manual target temperature change command is sent whenever the target temperature is changed, even through a downlink command.

Firmware version 3.5

Release date: 02 December 2021
  • Improved temperature measurement resolution from 0.62 to 0.18 degrees Celsius
  • Special command if the target temperature has been changed manually by the customer (by hand).
  • Open Window function change - Vicki fully closes the valve, regardless of motorPosition specified.
  • Changed default parameters:
    • Operational mode - changed from manual to automatic
    • Keepalive interval - changed from 3 to 10 minutes
    • tDiff (open/close) - changed from 1 to 0 degrees
    • Uplink type - changed from confirmed to unconfirmed
  • Send first keepalive packet as soon as the device completes Join procedure.
  • Added support for Advanced Motor Force Control of Vicki.
  • Improvement of the calibration mechanism
  • Bugfix - in previous firmware device reported -40 degrees after the communication watch-dog has restarted it.
  • Bugfix - report battery voltage values above 3.5VDC correctly
Known issues:
  • If pFirstLast or pNext is less than 17 steps, the device misbehaves
  • If one moves the motor with less than 17 steps in either directions, the device misbehaves
  • When device is in operational mode "Automatic with external temperature sensor" and it restarts due to power-off or Communications watch-dog, the device backs off to "Automatic" operational mode.

Firmware version 3.4

Release date: 07 January 2021
  • Minor bugfixes
    • Allow keepalive interval to be greater than 21 minutes
  • The internal temperature control algorithm now uses force close to close the valve.
  • Introduce WDP (Communication Watch-Dog Parameters); Set WDP parameters; Get WDP parameters
Known issues:
  • When the WDP activates and restarts the device, the first reading of the temperature is -40.
  • If battery voltage is > 3.5VDC, the device reports 2VDC. The device continues working correctly.
  • When device is in operational mode "Automatic with external temperature sensor" and it restarts due to power-off or Communications watch-dog, the device backs off to "Automatic" operational mode.

Firmware version 3.3

Release date: 27 October 2020
Known issues:
  • Keepalive interval cannot exceed 21 minutes
  • When device is in operational mode "Automatic with external temperature sensor" and it restarts due to power-off or Communications watch-dog, the device backs off to "Automatic" operational mode.

Firmware version 3.2

Release date: 28 September 2020
  • Initial release of Vicki LoRaWAN
