      @this.wiederkehr Ok .. maybe you right but this is beyond me , I think is beter to wait for @daniel and @bucknall opinion or fix solution.

      Thank you very much @this-wiederkehr

        Hello,

        While we find out why sometimes less calibration pulses are received, please use the new library that has a try-except block around the calibration:

              Have you fixed the 0.4mA consumption during deep sleep?

                @athtest800 are you talking about the Pysense or the deepsleep shield?

                  @daniel I am using the deep sleep shiled with lopy in breadboard (without expansion) by powering with 5V. The consumption is 500uA. Isn't it high? I thought it will be below 50uA.

                    @daniel I have issue with "deepsleep shield" and LoPy. It's stops after cca. 20 cycles. Same if added the "exception" block to calibrate method.
                    Running over serial the cycle ends into REPL and without error.

                      @tmz so it simply goes out to the REPL without running your code? Do you have any condition in your code that could cause that (exit the script instead of going into deepsleep)? Do you have anything connected to P12? Maybe at some point the board is booting into safe mode...

                        @daniel The deep sleep works! But then at one point without any error it's not entering into next deep sleep cycle instead is enter into REPL.

                          @tmz what you say is that after calling the go_to_sleep() the deepsleep shield doesn't put the LoPy to sleep?

                            @daniel Yes, executing go_to_sleep() some cycles works and than at one point it's not enter into deep sleep mode.

                            Do you have anything connected to P12?
                            Nothing connected to P12.

                            For debugging i was running connected over "Serial" to see what happens and for some time (cca. 5 - 20 cycles) works normally and then without errors enters into REPL.

                            code:

                                # Setup deep sleep mode
    ds = DeepSleep()
    ds.enable_wake_on_raise('P17')
    # Some work here
    ds.go_to_sleep(60)

                                @tmz Do you have a pull-down on P17? I think what is happening is that noise is waking up the deepsleep shield before it gets to turn off the LoPy completely. Please try putting an external pull-down to P17 and disabling the internall pull-up with the deepsleep library.

                                  @daniel said in Does deepsleep work at all:

                                  Do you have a pull-down on P17?
                                  I have plugged the P17 and GND to have an option to wakeup (with normally close switch) and set ds.enable_wake_on_raise('P17').

                                  Now tested "without plugging P17 with GND".
                                  Running the example from documentation:

                                  ...
ds.enable_pullups('P17')  # can also do ds.enable_pullups(['P17', 'P18'])
ds.enable_wake_on_fall('P17') # can also do ds.enable_wake_on_fall(['P17', 'P18'])
...

                                  With same result as before it runs 5 cycles and ends.

                                  At home i don't have any resistor i will let you know tomorrow.

                                    @chumelnicu Hi Daniel, sorry for late update but i was in holliday until yesterday.

                                    I did try deepsleep with new DeepSleep library and llopy behive same. After 14-15 DS cycles program stop running.

                                    I use lopy with DS Shield powered from USB and nothing on Pin12.
                                    Condition to wake up, is time, w-up after 10 minutes.
                                    Do u have any ideea what is wrong?

                                    Thx !

                                      @daniel The result is the same. Stops after (5 - 20) cycles. How do i run in more verbose way? There is no error, it's jumps into REPL.

                                        @daniel Could you tell me how and when DeepSleep will work ? Im not only one who claim about this problem and I think is really time to clarify with your team what is happening

                                        Thank you !

                                          I have the same problem with a LoPy + Deep sleep shield.
                                          My code runs for 20-40 times and then stops. Issue reported here: https://forum.pycom.io/topic/1685/lopy-with-deep-sleep-shield-is-unstable

                                          This is a blocker for any real world deployment.
                                          Not having seen any useful response from the Pycom team on the forum about this issue i am considering moving to another platform to get my project finished.

                                            Hello,

                                            The instability has been fixed here: https://github.com/pycom/pycom-libraries/commit/ea3e22c14884671801bcd1cfe49c703bc63c7078

                                            We are now working on reducing the deep sleep current.

                                            Cheers,
                                            Daniel
