I only need to run it twice before I start running into memory errors

📎 message.txt

this also happens with an unexpectedmaker featherS2, and subsequent runs always run out of memory in the same spot

Have you tried running this saved as code.py instead?

#

You can add a while True: loop before the fetching text statement to loop.

#

This is unusual.

#

I was just retrying to see how many times before I got the memory error

torn rock
#

OK. Can you try that? I am wondering if calling wifi connect and socketpool multiple times could be an issue.

jolly lake
#

I can put that outside of the function def so it runs once on import, but i believe that it would throw memory errors earlier if that was the case no?

#

II guess that was it... it swore I tired that before...

working code:

import ipaddress
import ssl

import socketpool
import adafruit_requests

import gc

    network.rssi, network.channel))
wifi.radio.stop_scanning_networks()

print("Connecting to %s"%os.getenv("CIRCUITPY_WIFI_SSID"))
wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID"), os.getenv("CIRCUITPY_WIFI_PASSWORD"))
print("Connected to %s!"%os.getenv("CIRCUITPY_WIFI_SSID"))
print("My IP address is", wifi.radio.ipv4_address)

ipv4 = ipaddress.ip_address("8.8.4.4")
print("Ping google.com: %f ms" % (wifi.radio.ping(ipv4)*1000))

pool = socketpool.SocketPool(wifi.radio)

  print("-" * 40)
  print(response.json())
  print("-" * 40)

#

How many times have you run that?

jolly lake
#

like 30

#

ill throw in loop

torn rock
#

Well, that seems good

jolly lake
#

yeah no issues in infinite loop
