Arduino Yun & pfodApp

Hi All,

I am attempting to control a switch using the pfodApp developer and application. The goal of my device is to trigger pump using a android app with all devices on my local network supplied by an internet hub. I have created my arduino code using the pfodDesigner tool which has been successfully uploaded onto my Yun. The issue I am having is when I try to connect to my Yun over the network using my android I have connection issues.

My local IP for the Yun is 192.168.1.6 however I am unsure how to port forward this local IP to allow for incoming connections from my app. From what I can gather I need to allow my app to connect to the arduino over the local network using the local IP 192.168.1.6. The following is my code uploaded onto my Yun. I am very new to arduinos so I do apologize for my limited knowledge. Any assistance would be greatly appreciated.

/* ===== pfod Command for Menu_3 ====
pfodApp msg {.} --> {.<+7>Sample On|A~<+2>Sample is `0~~Off\On}

// Using Serial1 and 115200 for send and receive
// Serial1 D0 (RX) and D1 (TX) on Arduino Leonardo, Yun and SparkFun FioV3 boards and D19 (RX) and D18 (TX) on Arduino Due and Mega boards

// give the board pins names, if you change the pin number here you will change the pin controlled
int cmd_A_var; // name the variable for 'Sample is '
const int cmd_A_pin = 4; // name the output pin for 'Sample is '

// the setup routine runs once on reset:
void setup() {
Serial1.begin(115200);
for (int i=3; i>0; i--) {
// wait a few secs to see if we are being programmed
delay(1000);
}
parser.connect(&Serial1); // connect the parser to the i/o stream
cmd_A_var = 0;
//pinMode(cmd_A_pin, INPUT_PULLUP);
pinMode(cmd_A_pin, OUTPUT); // output for 'Sample is ' is initially LOW,
//uncomment INPUT_PULLUP line above and set variable to 1, if you want it initially HIGH
digitalWrite(cmd_A_pin,cmd_A_var); // set output

// <<<<<<<<< Your extra setup code goes here
}

// the loop routine runs over and over again forever:
void loop() {
byte cmd = parser.parse(); // pass it to the parser
// parser returns non-zero when a pfod command is fully parsed
if (cmd != 0) { // have parsed a complete msg { to }
byte* pfodFirstArg = parser.getFirstArg(); // may point to \0 if no arguments in this msg.
long pfodLongRtn; // used for parsing long return arguments, if any
if ('.' == cmd) {
// pfodApp has connected and sent {.} , it is asking for the main menu
// send back the menu designed
sendMainMenu();

// now handle commands returned from button/sliders
} else if('A'==cmd) { // user moved slider -- 'Sample is '
// in the main Menu of Menu_3
// set output based on slider 0 == LOW, 1 == HIGH
parser.parseLong(pfodFirstArg,&pfodLongRtn); // parse first arg as a long
cmd_A_var = (int)pfodLongRtn; // set variable
digitalWrite(cmd_A_pin,cmd_A_var); // set output
sendMainMenuUpdate(); // always send back a pfod msg otherwise pfodApp will disconnect.

} else if ('!' == cmd) {
// CloseConnection command
closeConnection(parser.getPfodAppStream());
} else {
// unknown command
parser.print(F("{}")); // always send back a pfod msg otherwise pfodApp will disconnect.
}
}
// <<<<<<<<<<< Your other loop() code goes here

}

void closeConnection(Stream *io) {
// add any special code here to force connection to be dropped
}

void sendMainMenu() {
parser.print(F("{.")); // start a Menu screen pfod message
send_menuContents(); // send the menu contents for Menu_3
parser.print(F("}")); // close pfod message
}

void sendMainMenuUpdate() {
parser.print(F("{:")); // start an Update Menu pfod message
send_menuContents(); // send the menu contents for Menu_3
parser.print(F("}")); // close pfod message
}

// modify this method if you need to update the menu to reflect state changes
void send_menuContents() {
// send menu prompt

// send menu items
parser.print(F("|A~<+2>Sample is `"));

You need to do some linux programming on the Yun to get it to accept a connection and forward the data via the bridge to the Arduino sketch running on the AVR micro.
