TOPIC:

The battery indicator function of my HA-DSP exhibits some unexpected behavior: it goes from full (4 LEDs lit) directly to empty (no LEDs lit) with no intermediate indicators ever appearing (3, 2 or 1 LED lit), and back to full again after charging.

After fully charging the battery via USB, the battery indicator always shows full (4 LEDs), but if I leave the unit switched off, unplugged and unused for a few days, the battery indicator will show empty (no LEDs), even though the unit still has plenty of battery left and turns on and functions normally. Switching the unit off and charging via USB will bring the battery indicator back to showing full again.

I'd like to understand whether or not this type of battery indicator behavior is by design.

Please note that my HA-DSP underwent a battery replacement last year to successfully address a turn-on issue.

Hi
I have the same issue here. From 4 LED to a kind of blinking LED if the battery is low or empty. No LED steps between.
I there an improvement planed with the next software update?

The latest plug-in/firmware release (Rev 1.2 / 26th Aug 2019 / MAJOR UPDATE) appears to fixed this issue with my HA-DSP.

The battery also no longer drains down within a few days even with the unit turned off.

Download this plugin and update the firmware, charge up the battery, then retest for this issue.

Thank you for your answer.
I have the latest software, but the battery LED shows still 4 for full or 1 and 4 flash for a short time which may means empty.

I assume you went through the firmware update process? Running the latest software is not enough. The fix is in the new firmware.

My HA-DSP exhibited very similar symptoms before the firmware update: going from 4 LEDs to none within a few days from a full charge, even with no usage. The new firmware fixed this, along with the battery draining issue. It's been a few weeks from a full charge and the battery check still shows 4 LEDs. I have not run the unit off battery to see if the battery check goes down to 3 or fewer LEDs.

I wonder if you have the latest "firmware", it's different from the latest "software/aka plugin". Feature like control of the battery are actually under control of the "firmware". Please start a support ticket with our team, we're here to help "support.minidsp.com"

I see the same problem with the latest firmware. From an embedded systems point of view, I suspect the problem is in the software that handles the 'debounce'/detection of the front panel pushbutton state - at least with respect to the battery check. Looks like the software misses the state of the switch because of contact bounce and then gets into a state where it never sees any more switch transitions. Just s guess! Probably a very simple fix.
