# Wizfi210 connect

## Question

Asked by wtx on 2014-03-17 in Wireless.

My environment like this,I have two systems.Every system has been made up of MTU and Wizfi210. I want to raelize purpose that one MTU_1 send date to Wizfi210_1 by serial port or SPI(complete),as the same time Wizfi210_1 send data to Wizfi210_2 with AD-hoc(complete),at last the Wizfi210_2 send data to MTU2(complete)and PC(not complete).
The status that when PC communicate to Wizfi210_2 ,the Wizfi210_1 don’t communicate Wizfi210_2, only one client(PC or Wizfi210_1) visit the Wizfi210_2(serve).
If I set the Wizfi210_2 to client, meanwhile set at+nctcp.Wizfi210_1 can connect to Wizfi210_2 ,and Wizfi210_2 also connect to PC(serve),but the PC don’t receive data only connect.
If I set the Wizfi210_2 to serve,Wizfi210_1 and PC only one can connect it.
If I set the Wizfi210_2 to serve like this at+nstcp/at+nstcp,PC can connect,Wizfi210_1 can’t.
Do you have some methods to solve problem?
Thank you!

Hi

I don’t understand about your environment.
How to connect between WizFi210#2 and PC. Is it TCP?
Or else, is it connected between MCU#2 and PC using Serial Interface?

In other word, Do you want to use case 1 or case 2 or another case?

Thank you for your reply!
I want to choose case1.Selecting TCP,wizfi210#1 can send datato wizfi210#2,wizfi210#2 can send data to PC.But wizfi210#2 can’t send data to wifiz210#1 or wizfi210#1 can’t receive data from wizfi210#2.
These are wizfi210#2 setting
