i am receiving this response while reading meter using tcp/ip:Error reading DLMS packet: Destination addresses do not match. It is 17. It should be 16.

def handle_client(client_socket):
client = GXDLMSClient(True, 16, 1, Authentication.NONE, '', InterfaceType.WRAPPER)
try:
# Send SNRM request
print("Sending SNRM request...")
reply = GXReplyData()
data = client.snrmRequest()
if data:
client_socket.sendall(data)
time.sleep(1)
response = client_socket.recv(2048)
if not response:
print("No UA response received.")
return
print(f"Raw UA response: {response.hex()}")
ua_response = read_dlms_packet(client, response)
client.parseUAResponse(ua_response.data)
size = client.limits.maxInfoTX + 40
replyBuff = bytearray(size)

Hi, You have tried to…

Hi,

You have tried to connect without an authentication level where the client address is 16. The meter sends a reply where the client's address is 17. Check if you should connect with client address 17 from the meter documentation.

BR,
Mikko
