WD Firmware Update v02Jun2022

DSQD v2.1.06 (SUPER)/v2.10 (FPGA)/v2.0.05 (RF)

• Improve frequency diversity operation to eliminate an audible ducking of the output audio when one of the TXs is powered off.
• In frequency diversity mode, if one TX enters a low battery alert condition, a hard pan is forced to the other. Fix a bug where, if the other TX also reports a low battery condition, the receiver remains hard panned to that TX, even if the other TX no longer reports a low battery condition.
• Allow network initialization to run indefinitely instead of giving up after four seconds and never trying again. Permits device to be booted before network is available rather than requiring power sequencing.

DSQD v1.2.04 (SUPER)/v1.32 (FPGA)/v1.0.09 (RF)

• Improve frequency diversity operation to eliminate an audible ducking of the output audio when one of the TXs is powered off.
• In frequency diversity mode, if one TX enters a low battery alert condition, a hard pan is forced to the other. Fix a bug where, if the other TX also reports a low battery condition, the receiver remains hard panned to that TX, even if the other TX no longer reports a low battery condition.
• Allow network initialization to run indefinitely instead of giving up after four seconds and never trying again. Permits device to be booted before network is available rather than requiring power sequencing.
• Fix bug preventing Wireless Designer from properly updating firmware when used in "recovery" mode. Normal firmware updates not affected.

• Implement hi-resolution tx battery voltage reporting scheme for transmitters that support it. This adds a digit of precision, e.g. 1.12 volts vs 1.1 volts.
• Move the "COMPATIBILITY MODES" menu option to the top level menu to make it more convenient to access.
• Move the "PILOT TONE BYPASS" menu option to the "RF SETUP" menu.

WD Firmware Update v18Sep2020

DSQD v1.1.02 (SUPER)/v1.27 (FPGA)/v1.0.08 (RF)

• In the main page, don't print static labels for channel names to allow more space for the name itself. Generate a default channel name when the name string is empty to prevent showing a blank name field on the screen.
• Fix bug where out-of-range rx name length or frame description length resulted in the reading in of possibly invalid characters. When this happened the macOS version of Wireless Designer sometimes crashed when connecting to the device.

WD Firmware Update v06May2020

DSQD v1.0.18 (SUPER)/v1.27 (FPGA)/v1.0.08 (RF)

• Add RF board detection fault screen which appears if RF board not detected during start-up.
• 'hwstat' query now returns fault status bits as a decimal number:
  • bit 0: Antenna bias power fault (decimal 1)
  • bit 1: RF board detection fault (decimal 2)
  • bit 2: FPGA boot fault (decimal 4)
  If more than one fault exists, the query returns the sum of the codes, e.g. if both antenna bias power and RF board detection faults exist the query returns '3'.
• Add 'HARDWARE STATUS' page to 'TOOLS AND SETTINGS' menu. This displays antenna bias power, RF board detection and FPGA boot status, one of "NORMAL" or "FAULT".
• In Antenna Bias Power page, enabling bias power for an antenna now resets the antenna bias power fault status. This better handles the case where the user fixes the problem causing the fault and then re-enables bias power.
• Fix bug causing a premature burst of audio heard before system is fully initialized when tuned to an FM carrier already on the air when powering up.
