AirStack 0.4.1


23 October 2020

The Deepwave Digital team is announcing AirStack 0.4.1, a minor release that resolves a few bugs and improves performance.

New Features

  • Transceiver Temperature Sensor - The temperature sensor found on the AD9371 can now be accessed via the SoapySDR Sensor API.
  • Remote Firmware Upgrades - Software has been added to give users the ability to reload the FPGA from flash memory without performing a full power cycle. This tool will safely take the FPGA off the PCIe bus, reload the flash memory into the FPGA, then place the FPGA back on the PCIe bus. This process is very useful for upgrading AIR-T system in fielded operation.

Bug Fixes

  • Only spawn asynchronous worker threads in the event of a multiple channel stream. This should improve performance for single channel streams.

  • Fixed issue where the OS would hang during shutdown.


The AIR-T upgraded software and firmware are available for customers to download in the Developer Portal.

Please note that upgrading to AirStack 0.4.1 from 0.4.0 does not require a complete re-flash of the AIR-T. Upgrading from earlier releases does require a re-flash, however. Please see the associated installation procedures for further details.
