Add WiFi for Repeater

[Fexiven]

Getting better insights into repeater performance would be really useful.

Adding WiFi support to compatible devices could make it easier to monitor performance both locally and remotely.

Here is a small script to test my changes, it only has the net stats commands implemented but can easily be modified for all other commands

import socket
import struct
import json
import time

HOST = '<device IP>'
PORT = 5000

COMMANDS = [
    'A1|stats',
    'A2|stats.batt',
    'A3|stats.uptime',
    'A4|stats.sent',
    'A5|stats.recv',
    'A6|stats.noise',
    'A7|stats.rssi',
    'A8|stats.snr',
    'A9|stats.errors',
    'B1|stats.airtime',
    'B2|stats.rxairtime',
    'B3|stats.queue'
]

def send_framed_command(sock, command):
    # Frame: < + len (2 bytes LE) + command
    payload = command.encode()
    frame = b'<' + struct.pack('<H', len(payload)) + payload
    sock.sendall(frame)

    # Receive response (framed: > + len + payload)
    response = sock.recv(1024)
    if response[0:1] == b'>':
        resp_len = response[1] + (response[2] << 8)
        resp_payload = response[3:3+resp_len]
        json_str = resp_payload.decode(errors='ignore').strip()
        # Strip prefix before JSON
        json_start = json_str.find('{')
        if json_start != -1:
            json_str = json_str[json_start:]
        try:
            data = json.loads(json_str)
            print(f"Command: {command} -> JSON: {data}")
        except Exception as e:
            print(f"Command: {command} -> Error parsing JSON: {e} | Raw: {json_str}")
    else:
        print(f"Command: {command} -> Unframed response: {response.decode(errors='ignore').strip()}")

def main():
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
        s.connect((HOST, PORT))
        print(f"Connected to {HOST}:{PORT}")
        for cmd in COMMANDS:
            send_framed_command(s, cmd)
            time.sleep(0.2)  # Small delay between commands

if __name__ == '__main__':
    main()
