Gurux.Serial

Mikko,

I am developing Test application in which data will be read from meter via the serial interface.

Using Gurux.Serial we got the proper frame (means 7E to 7E )on the receive event.

But, If I am trying to read without Gurux. Serial in that case how to identify that start and end of the frame on the serial interface.

Can you please provide an update.

Hi,

Hi,

HDLC framing is a standard and it's defined here:
https://en.wikipedia.org/wiki/High-Level_Data_Link_Control

I have to say that you will save a lot of work if you can use Gurux libraries.
After you have HDLC frames you need to start to parse messages.

BR,
Mikko
