Seg 8: Mobile phone software

二. Mobile phone software

In nature, mobile phone software is the same as PC software. In this section, we will debug wifi module by mobile phone software.

  1. Install the mobile phone debug software EasyTCP (have iphone and Android versions, respectively. If you want them, you can contact me by skype: yichone.), in this experiment, we use the Android version EasyTCP.
  2. Open the wifi network at mobile phone, and look for the wifi signal HI-LINK_0021的wifi and double it to connect with the same way as PC version, as shown in Figure 2-12.

  3. Open the mobile software EasyTCP→click “CONNECT”→click “+” to add the connection IP address and port number, which is the same as PC software. IP is 192.168.16.254, and port is 8080, which are shown in Figure 2-13. Then click “connect” to let mobile phone connect to the wifi network HI-LINK_0021.

  4. At the same time, we should open the serial assistant. In this experiment, we must send the data from mobile phone to PC serial port by wifi network. In the later experiment, we would send the data from mobile phone to server on the cloud. In figure 2-14, data “5″ has been send to PC serial port by wifi network successfully.

2.5 Key notes and summaries

1) As for the new wifi board, we can make a preliminary judgment whether a wifi board can work normally by simply observing the display state of the LED light. But, we should note that the insertion direction when wifi board is inserted into a Arduino shield board.

2) when network-serial assistant is used to debug wifi module, it is noted that the wifi module should be recovery to the default factory setting and the software settings.

3) We should choose the wifi signal transmitted from wifi module to debug the wifi module, or we cannot use the wifi module for the wireless communication rightly.
