      Hi guys,

      I'm working on pytrack 2 deepsleep. What I see is that when I run a deepsleep for 6 hours, pytrack wakeup almost 10 minutes later... I'm the only one that deals with this problem. I have a DS3231 connected to pytrack, I have a chance to use this one for wakeup correctly? Using the alarm interrupt on the PIC. Any advice?

      thanks.

        Hi,
        Could it be related to you powering the device over USB? There is a 'feature' in the pysense that it will wake up immediately when powered over USB (which is not properly documented in the documentation yet)

          @Gijs Thank you so much for your answer! Yes, I'm powering the device over USB, is it possible that I get a different behaviour if I power it by +5V?
          Can you share how to enable the feature you talk about?

            Ah sorry, I forgot to mention. We made it such that when you plug in a battery, the pysense sleep feature will work as expected,. Im not sure about using a USB cable without data connections, but I believe we sense for the 5V coming from a USB connector.
