Mark 2 Firmware Release Notes

Arable Web Mark 2 Firmware Release Notes Doc Number: ARA2022-00001 Rev A Date: March 30, 2022

Release Overview

This firmware release is a limited release to support a new wind max definition based on 5 sec interval rather than 30 sec interval to better capture shorter wind gusts. The firmware is compatible with Arable Mark 2 hardware Rev 3.91, 3.1 and 3.0. 

The Arable Mark 2 Rev 3.91 is validated for use with AT&T in the US and globally as well as for Claro in Brazil. Arable Mark 2 Rev 3.1 is to be used for Telstra in Australia.

The use of Arable Mark 2 and Arable Solar with a 20-min sync interval for faster weather alerts is in a limited release as we build more field data for different geographies and conditions. You can reach out to Arable Customer Success at or via the Help icon in the Arable Mobile/Web to enable this on a per unit basis.

General Release


List of Changes

New Features

  • The Max Wind provided sampling interval has been reduced from 30 seconds to 5 seconds in this release. This rate is more aligned with the sampling rate for Wind Gust (5 sec sampling rate) and will generally mean that a higher value for Wind Max is shown than previously.

Defect Fixes

  • N/A

Known Issues

  • In order to ensure season-long operations of the Arable Mark 2, it is recommended to deploy with the external Arable Solar panel. 
  • The battery percentage value for the Arable Mark 2 can temporarily dip to zero if the system gas gauge resets. It will go back up to its actual value after a few minutes of retraining. At low voltage levels, close to the 3.1kV communications cut-off, the battery voltage can fluctuate widely and preemptively show zero even though it is possible to send data for a few more hours.  
  • The Mark 2 uses Satellite-based GPS to detect its location. If the unit is placed indoors, where no GPS signal can be retrieved, it will not be able to provide the correct location coordinates. This will in turn impact the user interface display in the Arable Web and the Arable Mobile. While we are exploring back-up capabilities for latitude/longitude retrieval, it is recommended for now to make deployments outdoors for full feature use.
  • There can be a small drift of a few seconds between the data collection windows in the Mark 2. This does not prevent the correct operations on the Arable Web and Mobile UI at an hourly time scale, but API users should be aware of this when aligning Mark data with other sources. 
  • The Arable Mark 2 firmware uses FIFO (First-In-First-Out) procedure for sending data over the network. If a unit has been active but not reporting for a while, this can create some wait time until the most current data is uploaded to the server.
