The Child’s (Raspberry Pi Pico W) code has been recovered (thanks to me making a backup) and now there’s additional code that lets it connect to the internet, currently a router that has no access to the internet.<\/p>\n\n\n\n
Currently, I am working with a Potato, dubbed Big Boi, to host a server that the Child will connect to, read, and display messages through its LED strip whenever Big Boi’s server message changes.<\/p>\n\n\n\n
Below will be the current code that has been added since last post’s slight<\/em> annoyance:<\/p>\n\n\n\n <\/p>\n\n\n\n import os<\/p>\n\n\n\n import ipaddress<\/p>\n\n\n\n import wifi<\/p>\n\n\n\n import socketpool<\/p>\n\n\n\n import adafruit_requests as requests<\/p>\n\n\n\n import time<\/p>\n\n\n\n print()<\/p>\n\n\n\n print(“Attempting to connect to WiFi…”)<\/p>\n\n\n\n print()<\/p>\n\n\n\n wifiConnect = False #flag to see if we are already connected<\/p>\n\n\n\n networkPool = os.getenv(‘CIRCUITPY_NETWORK_COUNT’)<\/p>\n\n\n\n for networkNum in range(1, int(networkPool) + 1):<\/p>\n\n\n\n ##Try next SSID<\/p>\n\n\n\n if not wifiConnect:<\/p>\n\n\n\n try:<\/p>\n\n\n\n thisSID = “CIRCUITPY_WIFI_SSID” + str(networkNum)<\/p>\n\n\n\n thisKey = “CIRCUITPY_WIFI_PASSWORD” + str(networkNum)<\/p>\n\n\n\n wifi.radio.connect(os.getenv(thisSID), os.getenv(thisKey))<\/p>\n\n\n\n print(“Success! Connected to WiFi network: ” + os.getenv(thisSID))<\/p>\n\n\n\n wifiConnect = True #Mark flag so we can stop trying to connect<\/p>\n\n\n\n pool = socketpool.SocketPool(wifi.radio)<\/p>\n\n\n\n # prints MAC address to REPL<\/p>\n\n\n\n print(“My MAC addr:”, [hex(i) for i in wifi.radio.mac_address])<\/p>\n\n\n\n # prints IP address to REPL<\/p>\n\n\n\n print(“My IP address is”, wifi.radio.ipv4_address)<\/p>\n\n\n\n except:<\/p>\n\n\n\n print(“Failed to connect to Wifi networ+: ” + os.getenv(thisSID))<\/p>\n\n\n\n #Pause if still not connected:<\/p>\n\n\n\n if not wifiConnect:<\/p>\n\n\n\n print(“=============================================”)<\/p>\n\n\n\n print(“Failed to connect to all known WiFi networks!”)<\/p>\n\n\n\n print(“=============================================”)<\/p>\n\n\n\n time.sleep(30)<\/p>\n\n\n\n <\/p>\n\n\n\n After that, this is the code for Big Boi’s server, quite small in comparison to the WHOLE of the Child’s code:<\/p>\n\n\n\n <\/p>\n\n\n\n from fastapi import FastAPI, Body<\/p>\n\n\n\n from pydantic import BaseModel<\/p>\n\n\n\n app = FastAPI()<\/p>\n\n\n\n # Store the last message in memory<\/p>\n\n\n\n last_message = {“text”: None}<\/p>\n\n\n\n class Message(BaseModel):<\/p>\n\n\n\n text: str<\/p>\n\n\n\n @app.get(“\/message”)<\/p>\n\n\n\n def get_message():<\/p>\n\n\n\n “””<\/p>\n\n\n\n Retrieve the last message sent.<\/p>\n\n\n\n “””<\/p>\n\n\n\n return {“last_message”: last_message[“text”]}<\/p>\n\n\n\n @app.post(“\/message”)<\/p>\n\n\n\n def post_message(message: Message):<\/p>\n\n\n\n “””<\/p>\n\n\n\n Post a new message and update the last message.<\/p>\n\n\n\n “””<\/p>\n\n\n\n last_message[“text”] = message.text<\/p>\n\n\n\n return {“status”: “Message updated”, “last_message”: last_message[“text”]}<\/p>\n","protected":false},"excerpt":{"rendered":" The Child’s (Raspberry Pi Pico W) code has been recovered (thanks to me making a backup) and now there’s additional code that lets it connect to the internet, currently a router that has no access to the internet.
