    Received my Mooshimeter today. Downloaded the iOS app, doesn’t show any Moooshimeter. Tried the “wake up” procedure. No LED flash, nothing in the app. Replaced the batteries and pressed the reset button., the LED flashed twice, then nothing. Still no connection to the app.

    Hmm… If the meter was rebooted but has not been through the wake up process, it will default to hibernating again. Can you try the wakeup procedure again?

    I tried the wake up process, nothing. No LED flash, nothing registers on the app.

    When in the hibernate state, is there a brief blink every 10 seconds? That brief flash is the time when it checks to see if the C and Ω inputs are connected together. So you have to connect the leads together until it blinks.

    Can you also just verify that the leads are plugged in to the C and Ω inputs?

    If you perform the above checks and still have no joy, it’s a failure mode I haven’t seen before and I’ll send you a return shipping label. Sorry for the trouble…

    Tried the wake up procedure several times, nothing. No LED flash, no connection to app.

    Oops, double post there.

    When I press the reset button, the LED lights for a second or so, then flashes (it’s a VERY brief flash) about every 10 seconds. But I can’t get it to wake up. I tested the continuity of the test leads, changed the batteries, reset it a couple of times, but nothing wakes it up.

    No worries on double post.

    If the flash is very brief to the point of being nearly imperceptible, the meter might have already woken up and is just not appearing in your scan list for some reason. Can you verify the kind of phone you’re using? And check the bluetooth is on? Some iOS users reported having to reboot their phones to get the meter to appear the first time.

    You made me realize I should change in firmware is there should be a clearer distinction in the blink pattern of standby vs. hibernate mode.

    Yea! Rebooting my iPhone got it to connect! It’s working now.

    Note to others. The hibernation flash is a definite though short double flash. The non-hiberation flash is barely perceptable.

    Rev. H 04/2014 was in storage and unused. New batteries after reset I get:
    Two long blinks, then a short blink. Then every 10 seconds, a short blink.
    It does show up on Bluetooth lists on iPad/Android phone/PC USB dongle.
    Tried shorting ohm-common and thought LEDs flashed for a while, but it now does nothing.
    I think this is stock older F/W so can you tell me the wakeup process.

    OOPS it does NOT show up on Bluetooth enumeration lists at all.

    Hi Ben,

    My first suggestion would be shorting ohm to common in case the meter’s in shipping mode, but you already tried that. So my next suggestion would be rebooting the phone, or replacing the batteries on the Mooshimeter. How long was it in storage?

    Let me know how it goes, best

    It’s never been used, new in the case but I put in fresh batteries.

    I measure 34mV across ohms-common, and 0.3uA shorting the two terminals together with another multimeter. It stays in hibernation.
    It doesn’t seem to have any voltage on the ohms terminal to notice anything.

    I am using three Bluetooth devices (iPad, Opo phone, PC USB dongle) and none can see the Mooshimeter.

    Was there an old (firmware) way to wake up the unit?

      Oh! Sorry, I misunderstood the issue.

      Apologies if you already know this, but I just want to make sure: have you checked that the devices you’re using support Bluetooth Low Energy/Bluetooth 4.0? iPad 1 and 2 don’t support BLE, and it looks like the Oppo runs Android 4.2, which doesn’t have BLE support. I don’t know about the dongle though.

      Could this be the issue?
