Hello everybody ,

I need your help where I am working on meter based on GSM sim808. I am creating TCP session using IP , PortNumber over sim808.

So , I need your help in the following :
- Required software tools to handle DLMS Protocol.
- preferred libraries and examples to be used to handle DLMS protocol using TCP session from GSM SIM808 meter.

finally , I would like to thank you for your help

Hi,

If you can make TCP/IP connection to the meter and it's supporting DLMS you can use GXDLMSDirector to read your meter. After you can read data you can your own app.

Hi Mikko,
Thanks for your Valuable response.
I am able to create TCP/IP Connection from meter as :
- Meter will be client.
- Reading System (GXDLMSDirector) will be server.

Regarding GXDLMSDirector what will be the device configuration where all configuration is for meter manufacturers and I am not one of those.

I will create TCP Connection using ;
- Global IP Address
- Port Number

hey
Now I am able to send information through gsm connected to microcontroller to server .

So, I need to connect microcontroller to meter through rs232 (uart) where it receives data from meter and sends it over gsm to server.

my question is ,

How can I get meter information through rs232 ?
choices :
1- Am I going to send something over rs232 (uart) to meter so meter respond with info .
2- Once I connect rs232 meter will send directly information to rs232(uart).

and also I need to know the size of the data sent from meter through rs232.

Great thanks from me to your valuable responses WHERE HONESTLY YOUR PAST RESPONSES HELPED ME ALOT.

Hi,

DLMS is very complicated protocol. You don't just send few bytes and get data back. You need to set right client and server address and sometimes you need to use authentication and password.

I strongly suggest that you'll make own app that collects data from the meter and your microcontroller only transforms bytes between the meter and head end system.

hi,

I am collecting data from meter through serial rs232 and sends it to my system (Server).

My questions are :

1- How can I get data from meter through rs232? where I will connect meter with microcontroller uart.
2- how can I test my work ?(Data gathering from meter).

Hi,

1. It depends on the meter. If you have RS-232 or RS485 you can use them. All meters have usually optical strobe. Then you might use it.

2. You can use GXDLMSDirector to collect data from the meter.
