How to run RAKOIT:BEP:0& without Windows?

Hi,

I got an S50+. I want to disable the beep of the remote and change volume control to do increments in 1 step instead of five. Been looking at the forum and found the command MCU+PAS+RAKOIT:BEP:0& that seems to be to be executed in some “Tool” that seems to be an exe-file. I’m on OsX and Linux. Is there a rest interface equivalent or something else to run those commands in?

I managed to write a python script based on some old documentation I found that fixed this:

import socket

debug = True
test_payload = True

def calculate_checksum(payload):
    return sum(payload)

# Set up the connection
ip = "192.168.1.52"
port = 8899
header = [0x18, 0x96, 0x18, 0x20]

if test_payload:
    payload_str = "MCU+VOL+050"
else:
    # turn off beep
    #payload_str = "MCU+PAS+RAKOIT:BEP:0&"

    # volume increments=1
    payload_str = "MCU+PAS+RAKOIT:VST:1&"

payload_bytes = [ord(c) for c in payload_str]

# Calculate the length of the payload
payload_length = len(payload_bytes)
length_bytes = [payload_length & 0xFF, (payload_length >> 8) & 0xFF, (payload_length >> 16) & 0xFF, (payload_length >> 24) & 0xFF]

# Calculate the checksum
checksum = calculate_checksum(payload_bytes)
checksum_bytes = [checksum & 0xFF, (checksum >> 8) & 0xFF, (checksum >> 16) & 0xFF, (checksum >> 24) & 0xFF]

# Add reserved bytes (assuming 8 reserved bytes as in the original example)
reserved_bytes = [0x00] * 8

# Create the full message with header, length, checksum, reserved, and payload bytes
message = header + length_bytes + checksum_bytes + reserved_bytes + payload_bytes
message_bytes = bytes(message)

#print([f'0x{byte:02x}' for byte in message_bytes])

if debug:
    print("---- DEBUG ---- ")
    print("Header:         ", bytes(header))
    print("Length:         ", bytes(length_bytes))
    print("Checksum:       ", bytes(checksum_bytes))
    print("Reserved:       ", bytes(reserved_bytes))
    print("Payload:        ", bytes(payload_bytes))
    print("My message:     ", message_bytes)

if test_payload:
    expected_message_bytes = bytes([0x18, 0x96, 0x18, 0x20, 0x0b, 0x00, 0x00, 0x00, 0xc1, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x4d, 0x43, 0x55, 0x2b, 0x56, 0x4f, 0x4c, 0x2b, 0x30, 0x35, 0x30])

    if debug:
        print("Expected message:", expected_message_bytes)

    # Compare the message_bytes and expected_message_bytes
    if message_bytes == expected_message_bytes:
        print("The message_bytes is correct!")
    else:
        print("The message_bytes is not correct.")


# Create a socket object and connect to the specified IP and port
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.connect((ip, port))
    
    # Send the new payload
    s.sendall(message_bytes)

    # Wait for a response (optional)
    response = s.recv(1024)
    print(f"Received response: {response}")

    # Close the connection
    s.close()
