Firmware v3.35
Dear all,
Unfortunately, I have just become aware that on April the 22nd 2025, I uploaded the wrong BAR-LT firmware file to our website.
This firmware file causes an error when saving wav files and can result in significant loss of data over a deployment!
It is critical that anyone who has downloaded BAR-LT firmware v3.35 from April 22nd until June 5th 2025 re-update their firmware to the correct file, (now called v3.36 to avoid confusion).
You can download the correct firmware file here: https://www.frontierlabs.com.au/software
Anyone who has deployed recorders with firmware 3.35 will only get one useable recording per day, in a file called "data".
I have written a program that recursively searches through folders to find, fix, and rename these "data" files to their correct useable wav files.
You can download it here:
To use it, put it in the root directory of your SD card (or wherever those files have been copied to) and double click the executable. It will show you a list of all the files that it has found and corrected.
It will look something like this when you run it:
If anyone has any trouble downloading or using the program please reach out and we will try our best to work it out.
Please accept our sincerest apologies. We understand the loss of data at critical times in a field season can be devastating along with the costs to visit and service your equipment can be significant.
Every attempt has been made to reach all of our customers, however if you know of other people using BAR-LT's during this time period, please pass on this message in case they are not in our contact lists.
Kind regards,
