Hi,

I’m using GXSerial (USB) without GXMedia to read DLMS meter data. During Association Response, I receive all OBIS codes in one large response frame, like this:

i am using gurux android project where not able to connect with the usb prob
prob details given below

man info:Silicon Labs:CP2102
USB to UART bridge controller
chipset:CP21XX
serial:0001
Boud rate:9600
data bits:8
parity :none
stop bits :1

Hi Mikko Sir,

I was looking through the forums and read some, but I'm still not sure if it is possbile to connect to DLMS Smart Meters and read data through bluetooth using the android app: https://github.com/Gurux/Gurux.DLMS.Android

Please provide some reference guides and a path on how can I implement such thing in my app, it is already reading data through HDLC interface using UART cable.

Thanks,
Kshitiz

Hi,

I am integrating Bluetooth communication using the Gurux Java library. The communication setup, including SNRM and AARQ requests, is working fine. However, the Association Request does not work with meters other than LGZ Single Phase over Bluetooth, even though it works correctly over serial communication. I verified that the Association Request sent over both serial and Bluetooth is identical, but only the Bluetooth fails to get a response. Please suggest what could be the possible issue."

Hi Sir,

I am getting below "Invalid Logical Name" while trying to connect Indian Standard Allied Meter which I am able to connect through DLMS Director App with same Parameters using Serial Connection but when I am trying to do it using Android APP I am getting "Invalid Logical Name" when clicking on "Open" button after putting Meter Properties.

how we can create serial dlms android app having Authentication encryption to connect to meter

BLE communication and reading of current values (without association) work correctly on all meters.

DLMS association (SNRM + AARQ) over BLE works only with the LGZ meter — the meter responds to chunked requests, and we receive replies successfully.

However, on other meters, the same association flow over BLE (sending the association request in chunks) fails — we do not receive any response after sending the AARQ.

Over USB/serial (using the same authentication level LOW), all meters respond correctly to the association request.

We would like to know:

in android project profile buffer in billing profile
