Optical port

Forums
Gurux.DLMS

Hello, i am trying to read data through optical port, but i have few questions:

1. Does meters always responds with all OBIS they have, when you write /?!\n\r.
2. Is it possible to read only one parameter instead of all?

I have two meters, both of them are responding everything they have instantly, when I write /?!\n\r

I am testing HDLCWithModeE.

Python - Datetime to Hex

Forums
Gurux.DLMS

Is it possible to convert datetime to hex string? I am using python. For example:

client = GXDLMSClient()
hex_str = "07E705180300000000800000"
dt = client.changeType(hex_str, DataType.DATETIME)
print(dt)

result: 05/24/23 00:00:00:000000

Now I want to convert from 05/24/23 00:00:00:000000 to 07E705180300000000800000.

Is it possible?

Reading gurux association logical name object.

Forums
Gurux.DLMS

Hello, i am trying to read association logical name object but i get Not enough memory available error.

I am trying to do as your client example says to read one bye one, but i never leave com_readDataBlock() method and com_readDataBlock() returns out of memory error. Should I read only one data block, parse it, then again read?
