Battery level stays at 0%

ReNNoReNNo
in Hardware
Hello all,

I purchased two PCS of Meta Wear R, charged, connected to my smartphone and they work great. But I also needed to implement some kind of battery monitoring in my app and I realized that one of these Meta Wear R devices always return 0% no matter if I plug it in USB. Other one works great.
I read somewhere that upgrading to the newest version of firmware should fix these problems but it didn't fix it.

Could it be hardware issue or I can test something else?

    Is the only issue with the 0% board the always 0% battery level i.e. everything else works just fine?  Also, what API calls are you using to read the battery level?

    I'm using this code:

    mwBoard.readBatteryLevel().onComplete(new AsyncOperation.CompletionHandler() {
    @Override
    public void success(Byte result) {
    ((TextView) view.findViewById(R.id.board_battery_level_value)).setText(String.format(Locale.US, "%d", result));
    }

    @Override
    public void failure(Throwable error) {
    ((TextView) view.findViewById(R.id.board_battery_level_value)).setText(R.string.label_sodium);
    }
    });

    Everything else works, only battery level stays at 0%.
    I have two identical MetaWear R devices, both are on the same firmware. One reports battery level just fine, other reports 0%. It only makes sense if board is defective.

    Since you're using the latest firmware, I presume that reading the battery through the Settings module also produces the same result?

    Also, Laura will follow up with you regarding this issue.

    Doesn't work neither.

    I didn't get any response for this issue? Should I report it again using support email or?
