Does deepsleep work at all

@daniel
I make now the execution
Deep sleep ends after 4 cycles.

@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.

tmz

@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 !

tmz

@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.

chumelnicu

@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 !

Robin

@adam_IoTK

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.

daniel

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

@daniel
Thank you! The issues seems to be fixed after this fix.
Is > 8h without interruption.

LoPy v1.7.9.b3

Robin

@daniel Seems to work for me too now.
Adding the garbage collector statements in the calling code seems to be crucial through.

johncaipa

@daniel I'm testing the deepsleep example but I get the following errors:

Traceback (most recent call last):
File "main.py", line 7, in <module>
File "/flash/lib/deepsleep.py", line 143, in get_wake_status
File "/flash/lib/deepsleep.py", line 76, in peek
IndexError: bytes index out of range

I am doing something wrong?
thanks

tmz

@johncaipa

Try the latest - https://github.com/pycom/pycom-libraries/blob/master/deepsleep/deepsleep.py

johncaipa

@tmz that is the library I'm using, and which errors are generated

https://github.com/pycom/pycom-libraries/blob/master/deepsleep/deepsleep.py

Just tried the deepsleep example on Sipy 1.0 - Pytrack 1.0 with latest deepsleep.py and after firmware upgrade to 1.7.9b3 and got the same error than John.

I understood that Pytrack serves as deepsleep shield.
All this deepsleep troubles merged with lack of documentation is really frustrating...

daniel

@Arnaud with pytrack or pysense simply use their own libraries which also provide the deepsleep functionality:

https://github.com/pycom/pycom-libraries/tree/master/pytrack

Arnaud

Nice to hear that! Please help us with a bit more explicit documentation. You might be aware of this now based on the comments, you're building up hours of frustration which is not was intended at first I'm sure with the beautiful specs of your products.

BTW, I think deepsleep example lacks an import deepsleep for constants.

Arnaud

@daniel I've tried the latest pytrack lib for deepsleep with very simple main.py:
from pytrack import Pytrack

print( "Waking up")

Some job

print( "Going to sleep")

pytrack = Pytrack()
pytrack.setup_sleep( 10 )
pytrack.go_to_sleep()

Waking up with a buton press works.
Board never wakes up on timer.

jcaron

Just to make sure, you have the latest firmware (0.0.4 I believe) on the Pytrack? You can check with pytrack.read_fw_version().

Arnaud

@jcaron read_fw_version returns 2.
Since I haven't done any pytrack firmware upgrades since June, I'll assume I have to.

This might be a hint for improving docs:
Required Pytrack Firmware: x.y.z

Arnaud

@jcaron
I have updated the pytrack firmware to 0.0.4 with DFU-util (Mac OSX).

From there:
The hearbeat (blue led) is not active anymore.
I have a lot of troubles gettting a console connection to the board.
Sometimes, the board executes main.py, prints a few lines but hangs on while printing firmware version and connection is lost.
