      @RobTuDelft it is, but not yet. The ULP coprocessor from the ESP32 has to be used for that, but we haven't enabled support for it yet.

        Some sensors have an "alarm" pin when values go below/over some threshold, with the deep sleep shield you could (in theory, I don't have it yet) connect those to either P17 or P18 and enable_wake_on_fall (or rise).

          @daniel Do deepsleep working ? I try to put my lopy after s.send(data) in lorawan config and after wake up 2 time from deepsleep the program is stop execution.

          Any solutions for that ?

          BTW ....I did try deepsleep from machine and alsi try with deepsleep board and DeepSleep from deepsleep.py library, same result

            @chumelnicu deep sleep works... Can you be more specific around the way your program stops execution? A code example and the REPL output would help us understand your issue. Thanks.

              @daniel Thx
              Was about reading HR-04 Ultrasonic Sensor and send data over lorawan.
              First i did connect Echo to Pin11 and Trigger to Pin12

              I just move it to Pin21 and Pin22 and seems all is ok

              Solved ! Thx Daniel

                Sure? Libs and Lopy updated today. Lopy attached to the DeepSleep board. Not even the first line of the example from Github or documentation works without an error

                  Do you happen to have another file named deepsleep.py in your LoPy root folder by any chance?

                      Setting aside the get_wake_status() example for now does a straight up

                      from deepsleep import DeepSleep
                      ds = DeepSleep()
                      ds.go_to_sleep(30)
                      

                      put the board into deep sleep for 30 seconds?

                        @Camot do you have anything connected to P10? That's the pin used between the LoPy and the deepsleep shield for communication...

                          put the board into deep sleep for 30 seconds?

                          don't think so, the board become unresponsive for 50 seconds but heartbeat continues and then it reports

                          >>> ds.go_to_sleep(30)

                          Repeated it 3 times with ds.go_to_sleep(30), alway 50 seconds unresponsive :/

                          @daniel
                          no, only the Lopy, the deepsleep shield, the antenna and power with a 3.3V Step-Up/Down Regulator on the Lopy 3.3V pin.

                            That's the problem then, the deep sleep shield only controls - and is powered by - the Vin (labelled 5V) pin not the 3.3V.

                            Try applying your 3.3V to the Vin pin instead, the LoPy regulator should enter bypass mode and hopefully the PIC10 and extra circuitry shouldn't be affected too much.

                              Oh, I have not read it anywhere yet. Thank you @jmarcelino
                              It works with 3.3V on the 5V pin at the DS shield. The power consumption goes down to 0.4mA during deep sleep....but more than I have expected. Besides the high deep sleep current, I found something else that's odd. If I put 5v to the 5v pin, the Lopy does nothing. If I put in 3.3v at the same 5v pin, it is starting. And yes, I am using the 5v pin ....first pin right to the heartbeat.

                                Can you explain it a bit better please? Where are you supplying 5V from? Is this with the LoPy inserted into the Deep Sleep shield?

                                    @Camot the deepsleep shield has a battery protection mechanism (LiPo batteries get damaged if you discharge them completely), therefore when the input voltage falls close to 3.3V, the deepsleep shield will disconnect power to protect the battery. This threshold voltage can be increased with the set_min_voltage_limit() and enable_auto_poweroff() methods from the deepsleep library. In any case trying to power it with a voltage that is too low won't damage anything.

                                    What do you mean with so many hardware bugs? Besides the deepsleep problem that we already acknowledged, and we did our best to compensate with the deepsleep shield, what other hardware issues have you found?

                                    Cheers,
                                    Daniel

                                      Hi all!
                                      I recognized a similar behaviour with my Lopy. The DS-shields arrived yesterdayand I start to work with them. My hardware setup is pretty simple: Expansionboard V2.1A, DS shield V1.0, LoPy, 2000mAh LiPo, attached to the Expansionboard and powered by USB.
                                      I start with upgrading a OTAA LoRaWAN node. It work for a while, then it stopped working with:

                                        Lopy + DeepSleep Shield after 10-12 cicles of 10 minites deepsleep stop working to0

                                        I use deepsleep.py library

                                        I really think is one bug with deepsleep function

                                          Hi @Thosch42,

                                          Could you please share which version on the deepsleep.py library you are using? I think myou might be on an older version of the library.

                                          You can find the latest version, here - https://github.com/pycom/pycom-libraries/tree/master/deepsleep

                                          Let me know if this helps,

                                          Thanks!

                                          Developer Evangelist - Pycom
