Battery Time

[bradnz]

Hi

I have a SiPy connected to the expansion board v2 and a 500mAh battery. When this battery is fully charged though I can only ever get at most a few hours run time on the whole device.

I cant see how the device, with bluetooth and WIFI deactivated can possibly consume even 100mA.

Any suggestions? The code is:

Boot.py:

from network import WLAN
from machine import UART
from network import Bluetooth
import os
uart = UART(0, 115200)
os.dupterm(uart)
wlan = WLAN()
bluetooth=Bluetooth()
wlan.deinit()
bluetooth.deinit()

Main.py:

import pycom
pycom.heartbeat(False)

Is the serial management consuming power waiting input?

@bradnz
WLAN.deinit() doesn't actually turn the peripheral off yet, it still consumes roughly the same.

What do you mean by it "doesnt turn it off yet"? I saw an SSID broadcast from the device before I applied that command, and then I didnt when I applied that command. The device goes through a lot of power in my opinion. I cant see how you can power this with a battery alone. Kind of defeats the purpose of a IoT device really.

It's one of the features being worked on, for now .deinit() only disables the software device it doesn't power it off.

Should be coming in a future update as well as the power saving modes (deep sleep etc) you need to operate on battery power.

Ok, great. Thanks.
