Roving Networks Wifly RN-111B User Guide Version 1.16 2. Introduction Scope This Integration and Users Guide, along with the RN-111b module have been developed to assist users in embedding Wifi technology into their serial, SPI, and sensor devices. The goal is to make the implementation of embedded Wifi wireless networks as seamless and easy as possible. This document will explain how to setup and establish communications between the RN-111b and Wifi enabled networks for data applications. 2.
Roving Networks Wifly RN-111B User Guide Version 1.16 2.2 Configuration Command Mode (vs Normal Data mode)- Upon powerup, the device will be in data mode. To enter command mode, The characters “$$$” must be sent. The device will respond with “CMD”. To exit command mode, send “exit”. The device will respond with “EXIT”. Parameters, such as the SSid, Channel, IP address, Serial Port settings, and all other settings can be viewed and configured.
Roving Networks Wifly RN-111B User Guide Version 1.16 3.0 WiFLY Command Reference The commands begin with a keyword, and have optional additional parameters, generally space delimited. Commands and options are case sensitive. hex input data can be upper or lower case. String text data, such as SSID, are also case sensitive. The first keyword is fully decoded, and the optional parameters can be short-formed.
Roving Networks Wifly RN-111B User Guide Version 1.16 3.1. SET COMMANDS These commands begin with “set”. There are 6 major categories. 1. COMM- communication and data transfer, timers, matching chars. IP -IP settings. SYS - system settings such as sleep and wake timers. TIME - timer server settings. UART - serial port settings such as baudrate and parity. WLAN - wireless interface settings, such as ssid, chan, and security options. 2. 3. 4. 5. 6.
Roving Networks Wifly RN-111B User Guide Version 1.16 set ip remote set ip ftp sets the remote host port number. sets the ftp server address. set ip uport sets the ftp server port number. SYSTEM PARAMETERS set sys autoconn TCP mode: sets the auto-connect TCP timer. 0 disables. set sys autosleep UDP mode: sets the auto-sleep timer. 0 disables. set sys iofunc set sys mask sets the IO port alternate functions. Bit-mapped value.
Roving Networks Wifly RN-111B User Guide Version 1.16 set uart flow <0,1,x> sets the flow control mode. 0=off, 1= hardware RTS/CTS, x = XON/XOFF. set uart tx <0, 1> Disables or enables the TX pin= PIO0 of the UART. set PIO0 to an INPUT with weak pulldown. Disable will WLAN PARAMETERS set wlan auth sets the authentication level. 0= disabled, 1=WPA-PSK, 2=WPA2-PSK, 3=WEP-128. set wlan channel sets the wlan channel, 1-13 is the valid range for a fixed channel.
Roving Networks Wifly RN-111B User Guide Version 1.16 3.2. GET COMMANDS These commands begin with “get”. They represent the stored values as configured. get com display comm. settings. get ip display IP address and port number settings. get mac display the device MAC address. get port return current value of the PIO pins in hex format. get sys display system settings, sleep, wake timers, etc. get time display the time server UDP address and port number.
Roving Networks Wifly RN-111B User Guide Version 1.16 3.4. ACTION COMMANDS $$$ Enter command mode Characters are PASSED until this exact sequence is seen. If any bytes are seen before these chars, or after these chars, in a 1 second window, command mode will not be entered and these bytes will be passed on to other side. close Causes a network disconnect to occur. exit Exit command mode. Exit command mode. “EXIT” will be displayed.

Roving Networks Wifly RN-111B User Guide Version 1.16 4.0 System timers and other features There are 2 timers that can be used to put the module to sleep, and perform a wake up. If the sleep timer is enabled, the module will automatically go into low power mode after the timer counts down to 0. The countdown is disabled if the module has an IP connection, or the module is in COMMAND mode. The timer is reset when characters are received on the UART.
Roving Networks Wifly RN-111B User Guide Version 1.16 4.2 Wake on UART When the module is in Sleep mode, the UART itself is disabled. However, wake on UART can be accomplished using a resistor divider from the data RX pin to the SENS1-4 pin. Good values for this are a 24K ohm resistor in series from RX to SENS1, and 10K ohms from SENS1 to Ground. To enable or disable this function, use: set sys trig 1.
Roving Networks Wifly RN-111B User Guide Version 1.16 4.4 Setting PIO directions, Disabling LED drivers The table below shows the usage of the PIO pins and their default values: Use the command: set sys mask to enable or disable certain pins as outputs. For example, set sys mask 0 will default all pins to INPUT. Note that PIO 7, and 8 are used internally by the module and cannot be changed. Setting or clearing bits in these locations will be ignored.
Roving Networks Wifly RN-111B User Guide Version 1.16 5. FTP Upgrade and Image Storage Image Storage WiFly contains a built file system for storing the firmware image(s). Files can be viewed with the ls command. Here is an example result: File# Size 2 12 wifly-1.05 14 1 config 113 Free, Boot=2, Backup=22. Multiple files can be stored, and the boot image can be modified per below. FTP Upload and Upgrade WiFly contains a built in FTP client for getting files and updating the firmware.
