Re: Welcome to the LabVIEW Communications Discussion Forum!

I am doing a project "Ethernet based Smart house using LabVIEW".

So how can the house  send a SMS or e-mail to the user when any abnormal situation will be happened?

Can we use a GSM module or any other method is there?

Please help me for the above case.

You are still posting in the wrong forum and in an unrelated thread. This forum here is about software defined radio (SDR).

Re: Welcome to the LabVIEW Communications Discussion Forum!

HEllo! 

 

I have a problem, I'm using the Tx and Rx example in Labview Communications between 2 URSPs with QPSK modulation, and applying coding (LDPC + BCH), the problem is when I demodulate the output bitstream from the QPSK demodulator is always changing (always receiving) and it changes too quickly I can't properly decode and compare to the original PN sequence sent. Is there a way to obtain a fixed output bit stream? I would really appreciate help in this matter!

So why don't you start a new thread for a new problem?

Re: Welcome to the LabVIEW Communications Discussion Forum!

Hello,

 

I want to transmite a bpsk signal over the SDR 2901 (teaching bundle ) but i get this error : "Error -1074118645 occurred at niUSRP Write Tx Data (CDB WDT).gvi"

I have decreased the IQ rate , increased the number of bits to be generated but nothing helped so far.I can t understand why it is not working.

I really need help for this project.

Re: Welcome to the LabVIEW Communications Discussion Forum!

Your last comment is the key. When you run a VI with Highlight Execution, LabVIEW Communications forces your host code to run in one thread. It is physically running slower, but still trying to interact with real-world I/O that is obviously not slow. So you will see weird things like buffers overflowing, etc. when running in Highlight Execution. Highlight Execution is just a debugging tool.

 

Cheers,

Rahul B.
