LoPy 4 - Current consumption and Deep Sleep

[cduplouy]

Thank you for your reply !

Here's what I get with the os.uname() command :

(sysname='LoPy4', nodename='LoPy4', release='1.15.0.b1', version='v1.8.6-849-baa8c33 on 2018-01-29', machine='LoPy4 with ESP32', lorawan='1.0.0', sigfox='1.0.1')

About my setup, I use an external 10kOhm pull down resistor and the pin P13. Here's how I configure the pin :

from machine import Pin
import machine

pinAlert = Pin('P13', mode=Pin.IN, pull= Pin.PULL_DOWN)
machine.pin_deepsleep_wakeup(['P13'], machine.WAKEUP_ANY_HIGH, True)

The other part of the main :

import myClass
import time

remote = myClass.Remote()

if machine.reset_cause() == machine.DEEPSLEEP_RESET:
	print('woke from a deep sleep')
	print(machine.wake_reason())
	remote.send_msg()
	time.sleep(1)
	machine.deepsleep()
	
else:
	print('power on or hard reset')
	remote.connect()
	print("going to deepsleep")
	machine.deepsleep()

If needed here are my connect and send_msg functions from the class Remote :

def connect(self):
	self.lora.join(activation=LoRa.OTAA, auth=(self.deveui, self.appeui, self.appkey), timeout=0, dr=0)
	while not self.lora.has_joined():
		time.sleep(parameters.DELAY_BETWEEN_ATTEMPTS)
	print('CONNECTED')
	self.lora.nvram_save()

def send_msg(self):
	print("SENDING LORA MESSAGE")
	self.lora.nvram_restore()
	try:
		self.socket.setblocking(True)
		self.socket.send(bytes([0x01]))
	except Exception as ex:
		print("Error: {0}".format(ex))
	finally:
		self.socket.setblocking(False)
		self.socket.settimeout(parameters.SOCKET_TIMEOUT)
		self.lora.nvram_save()

Thanks for your help !

@cduplouy
Also how are you going to deepsleep and wake up on a button press? Can you show that part of your code and describe your setup?

Thanks

@cduplouy
do you have current firmware?
You can check firmware by:

import os
os.uname()
