The firmware was made available to me, from Batbox, Ltd., to review and explore, etc. It will be made available, for all Griffin owners, on their Firmware Update Page Here - In about a week.
If your system is up to date (Ver.22) then, just before the update (to Ver.23) your firmware info should read similar to this:
Upon launching the upgrade application, it will begin it's (short) process, by displaying the following:
"Doing upgrade, please wait" and the system will begin to perform the upgrade on itself...
Eventually, the final text displayed on the screen will read:
ToGo: (The seconds count down) 98..97....42...31... Until the system powers itself off (upon completion).
When you next power the unit on, the system will go through a few more upgrade-related splash screens (automatically) and will then return to the ready state.
If one checks the firmware status, the display should read something like this:
Which indicates that the upgrade has completed successfully.
At this time, I don't have any solid specifics to report. Since this firmware upgrade is so new, the official documentation has not been made available to me yet.
Also, It is currently 4:00 AM here in the Northeastern United States, and the peak times for (best) bat activity has already passed. I hope to test it's unattended recording improvements tomorrow night.
Happy bat detecting!
