Socket Demo

In this application one emulator acts as the socket server, and the other as the socket client.

1. In the first emulator, launch the application, then select the Server peer. Choose Start. The emulator explains that the demo wants to send and receive data over the network and asks, “Is it OK to use network?” Choose Yes. The Socket Server displays a screen that indicates it is waiting for a connection.

2. In the second emulator, launch the application, select the Client peer, then choose Start. The emulator explains that the demo wants to send and receive data over the network and asks, “Is it OK to use network?” Choose Yes. The Socket Client displays a screen that indicates it is connected to the server. Use the down navigation arrow to highlight the Send box. Type a message in the Send box, then choose the Send soft key.

   For example, in the client, type Hello Server In the Send box. Choose the Send soft key. The emulator activates a blue light during the transmission.

3. On the emulator running the Socket Server, the Status reads: Message received - Hello Server. You can use the down arrow to move to the Send box and type a reply. For example, Hello Client, I heard you. Select Send.

4. Back in the Socket Client, the status shows the message received from the server. Until you send a new message, the Send box contains the previous message you sent.
