DeepSleep Shield & LoPy

[athtest800]

Hi!
I have connected DeepSleep Shield and Lopy without! the expansion board and I get 0.500mA in deep sleep.
Is that OK? How can I get uA?

import pycom
import time
from deepsleep import DeepSleep
from network import WLAN

wlan = WLAN()
wlan.deinit()

ds = DeepSleep()

pycom.heartbeat(False)
for cycles in range(1): # stop after 10 cycles
    pycom.rgbled(0x007f00) # green
    time.sleep(5)
    pycom.rgbled(0x7f7f00) # yellow
    time.sleep(1.5)
    pycom.rgbled(0x7f0000) # red
    time.sleep(4)

ds.go_to_sleep(20)  # go to sleep for 20 seconds

Thank you.

Noone can answer if the deep-sleep board is using 500uA during sleep? or 10 uA (as described) ?

I am doing power comsumption test with LoPy and Deep-Sleep Shield too.
The LoPy firmware is 1.8.0.b1 and the DeepSleep library from Github has been modified 3 days ago.

I am doing the test with a power supply and a tester in series.

With the expansion board, the device uses around 620 uA.
Only with Deep-Sleep Shield I am measuring 520 uA.

Even power down WiFi and Bluetooth, the power comsumption is the same.

What I am doing wrong?

On the other hand, power comsumption for Pysense and Pytrack in deep sleep mode are better, around 9 and 17 uA respectively.

I also have 520 uA (with the DeepSleep Shield and no expansion board) with a Wipy 2.0 (instead of few uA)

Also measuring over 500 uA with a LoPy + deep sleep shield, which is a shocking amount of current.

To continue using the LoPy, i have had to use a humungus sized battery (6600 mAh) and shorten the life-span of the device.

Please fix this pycom guys. This has taken far too long!
I like the LoPy, but if this is not fixed pretty soon i will be forced to switch to a low power arduino alternative.
