Seg 1: WIFI wireless communication module serial debug based on the Arduino shield board

2.1 Problem presentation: how to use serial tools to debug wifi module?

In this part, we will discuss whether a new wifi module works normally. For this purpose, we can from the following two aspects.

  1. From the wifi hardware, we can judge whether a new wifi module normally work from its pilot lamp;
  2. By using the serial tools to debug the wifi module from software. Note that, in this section, the serial software includes mobile and computer (PC) version.

2.2 Hardware and software

For debug whether a new wifi module normally work, we need the following hardware and software, as shown in Table 2-1.

Table 2-1 the required materials


name quatity function note


Wifi module 1 Wireless communication


Arduino shield 1 Wifi connection


USB to RS232 1 Transformation and connetion


5V1A voltage adapter 1 Provide voltage


antenna 1 Transmit wifi signal


PC tools 1


Mobile tools 1

The required materials are shown in Figure 2-1.
