Pytrack and Gpy in deepsleep waking on gpio

[jupiter8]

Hi,

Can anyone can give me a good start on putting the Pytrack/Gpy combo in deepsleep and waking up from a gpio and returning to sleep?

I want to use it as a flow detector where a simple float (switch) can be use as waking the module up and sending some ON/OFF status and return to sleep. I already have code to send messages on gpio triggering:

Thanks.

from network import LTE
from machine import Pin
from umqtt import MQTTClient
import machine
import time


is_pressed = False
button = Pin("P10", mode=Pin.IN, pull=Pin.PULL_UP)




def settimeout(duration):
     pass
lte = LTE()

 # Modem does not connect successfully without first being reset.
print("Resetting LTE modem ... ", end='')
lte.send_at_cmd('AT^RESET')
print("OK")
time.sleep(1)

print("Configuring LTE ", end='')
lte.send_at_cmd('AT+CGDCONT=1,"IP","yourAPN"')
print(".", end='')
lte.send_at_cmd('AT!="RRC::addscanfreq band=2, 4, 5 dl-earfcn=9410"')
print(".", end='')
lte.send_at_cmd('AT+CFUN=1')
print(" OK")

if not lte.isattached():
    print("Attaching to LTE network ", end='')
    lte.attach()
    while(True):
        if lte.isattached():
            print(" OK")
            break
        print('.', end='')
        time.sleep(1)

    # Once attached, connect() should succeed.
    if not lte.isconnected():
        print("Connecting on LTE network ", end='')
        lte.connect()
        while(True):
            if lte.isconnected():
                print(" OK")
                break
            print('.', end='')
            time.sleep(1)
lte.connect()
while not lte.isconnected():
    machine.idle()

print("Connected to LTE\n")
#wlan = WLAN(mode=WLAN.STA)
#wlan.antenna(WLAN.EXT_ANT)
#wlan.connect("yourwifi", auth=(WLAN.WPA2, "yourpass"), timeout=5000)

#while not wlan.isconnected():


#print("Connected to Wifi\n")
client = MQTTClient("joe", "yourMQTTbroker", port=1883)
client.settimeout = settimeout
client.connect()

while True:
    if button() == 1 and not is_pressed:
        time.sleep(1)
    elif button() == 0 and not is_pressed:
        print("Button pressed")
        print("Sending ON")
        client.publish("/gpy", "ON")
        is_pressed = True
        time.sleep(1)
    elif button() == 1 and is_pressed:
        print("Button released")
        print("Sending OFF")
        client.publish("/gpy", "OFF")
        is_pressed = False
        time.sleep(1)
    else:
        pass

Hi,
I'm having the same problem right now. From what I've figured out so far, there's an interrupt on P#9 which can be configured through the py.setup_int_pin_wake_up(False) method. I haven't gotten it working so far, though. I have also created another topic asking a similar thing.

Alternatively, you can sleep through the machine.deepsleep method and configure any GPIO as wakeup pin for that. YMMV though, as I am experiencing extremely high sleep current with the machine deepsleep.
