# What is the reply port?

## Question

Asked by soellicha on 2015-09-06 in Wireless.

Hello,

I use a TCP client app on an android to send data to MCU through wizfi250. Wizfi has an IP 192.168.12.1 and port 5000 to receive data.
The android device IP is 192.168.12.2
My question is at which port the wizfi replies the data to the android device?
Can I use multiple android devices speaking to wizfi?

Thank you,

Best Regards,

Andreas Achilleos

Hi, Andreas Achilleos

You have to set the port number at android app.

Please refer to the following image. It is tcp terminal application.
The image linked below means that android app for tcp connection should be able to set a port number.
