Introduction

I wrote this page for test the tcp/ip communication between the mbed and an Android phone.

Required Components

• mbed board with ethernet connector
• Android App Terminal Multi (Google Play Download)

Ethernet Schematic

In this example I used the SI-60002-F RJ45 connector without leds.
In the below photo I summarized the schematic:

How works

First you must connect the mbed and the phone to the same network.

In this test the mbed works as server with address ip 192.168.153.153 and it is connect directly to the router.

Instead the client (Android phone) have this address ip 192.168.153.100.

Now in Terminal Multi you can create the connection and start sending the messages. You can see the messages received with a usb terminal.

The goal is send a message by android and receive a feedback message (CMD Received) by the mbed.

Code

Example

You can setting the address ip and the port by the below menu

Then you can start the connection with mbed. The black ball will turn green color when the connection is established.

The output is (if you send a message you will receive a "CMD Received" message from mbed):
