... PIC16 and PIC18 microcontroller families. The PIC18 Explorer Board’s 8-bit microcontroller communicates with the RN-131-PICTAIL/RN-171-PICTAIL evaluation board via the PICtail connector. This document describes how to use the RN-131-PICTAIL/RN-171-PICTAIL evaluation board connected to a PIC18 Explorer Board to associate with a Wi-Fi network and communicate with other devices within a LAN. Communication with other LAN devices is performed using telnet ...

... PIC recognizes. Set Up Hardware Perform the following steps to set up the hardware and prepare it for configuration: 1. Plug the RN-131-PICTAIL/RN-171-PICTAIL evaluation board into the PIC18 Explorer Board’s PICtail connector. See Figure 1. Figure 1. Modules Connected to PIC18 Explorer Board RN-171-PICTAIL Connected to the PIC18 Board 2. Configure the PIC18 Explorer Board’ ...

... RN-131-PICTAIL/RN-171-PICTAIL, temporarily bypassing the PIC (this step is specific to the PIC18 Explorer Board). 2. Open your terminal emulator to the COM port of the PIC18 Explorer Board/RN-131-PICTAIL/RN-171-PICTAIL. The serial port settings are 9600 baud, 8-bits data, no parity, 1-stop bit, and no flow control. www.rovingnetworks.com   ...

... Press the MCLR reset button on the Explorer 18 board and observe the output transaction on the terminal emulator console. A normal sequence is similar to that shown in Figure 5, i.e., the device is associated with the designated access point, and the yellow LED on the RN-131-PICTAIL/RN-171-PICTAIL is illuminated. www.rovingnetworks.com   ...

... The RN-131/RN-171 module is now associated to an access point and is operating in data mode. Use the following steps to open a telnet session with the device and send it commands: 1. Associate your computer’s Wi-Fi connection with the same access point as the RN-131/RN-171 module your computer, open a command line session and type the command: telnet < ...

... Initialize the PIC18 Explorer Board Hardware During this processing stage, the void BoardIint(void) API function performs the following tasks: • Chooses the external 10-MHz crystal as the clock source. • Configures the ports/pins as digital and selects their direction to match the functional requirements of the PICtail connector. • ...

... Explorer Board and UART are properly initialized. The void rn_reset_wifi(void) API function is used for this reset operation. It transitions the reset pin from high to low, holds the pin low for 10 ms, and then returns it high. This reset action triggers the module to begin its joining procedure. ...

... This function accepts 2 or more parameters (i.e., a variable length parameter list). The first parameter, response, is the reply expected from the RN-171 module after it has processed the command. The command is carried in the fmt parameter. For example, if the function is called as follows: retValue = err_t module_send_cmd(“ ...
