hello sir,
how can i read data using Gurux serial component for discovery RF nodes which are connected in meters. Because in discovery of node there is no fix length of data and also EOP is not there.

Hi,
If there is no fixed length or EOP you must read data until all data is received.
Pseudo code is something like this:
serial.Send(Data to send, null);
do
{
serial.Receive(p);
}while(check that packet is received);

Hi,
Set count to 1 if you do not know how many bytes to wait. One byte is read then you can check is packet fully received.

hi sir
i have set count to 1 and i am still getting same exception message. what condition should i apply to check packet is received in gurux serial.
Want to read data for discovery RF node
Hi,
You must set it each time before calling Receive. We are resetting count after data is read.
Like this:
serial.Send(Data to send, null);
do
{
p.Count = 1;
serial.Receive(p);
}while(check that packet is received);
