Seg 6: Software settings

2.4 Software debug

You can also use computer (PC) and/or mobile phone software to debug the wifi module. After the connection among the wifi board, Arduino shield board, USB to RS232 cable, and power, then we can test the wifi module shown by the following.

一. Computer (PC) version software

(1) software setting

Open the network serial software (which can be download from the website, if cannot find, can be contact me by my skype: yichone). Firstly, we should set simply the software environment, as shown in Figure 2-6, especially for the red label.


Figure 2-6 Simple settings for the PC network serial debug software

Some notes on the settings:

  1. PortNum: can be found at “computer (or my computer)”→right click “property”→click “device manager”→click “COM and LPT”. We can get the PortNum is COM6. So, we choose “COM6″ in the software, as shown in Figure 2-7.


Figure 2-7 query of PortNum

  1. Baud rate (BauR): during the wireless communication, the rate is generally chosen as 115200. It is also the wifi transmission rate 11MHz.
  2. Protocol: during the wireless communication, we should let wifi module as TCP Client mode. In other words, let wifi as client to visit the server.
  3. ServerIP (server IP address): :in the default factory setting, please input the IP address: 192.168.16.254. Note that, in the default factory setting, the IP address is 192.168.16.254. However, if the wifi board has ever been used, the IP address maybe is not this address. So, before using it, we must confirm the default factory setting for the wifi module. The way to default factory setting is introduced at Section 2.3.
  4. ServerPort (server port): the value is 8080.
