Non Synced Key Fob causing id issues

[irishhawk]

Hello,

I am currently having an issue with the photon system where if a non synced key fob button is hit the device will give a 0 (unidentified ID) on the next button press from a synced key fob. Once you hit the synced key fobs button again you will get the correct ID of 1. Is there a way to keep this from happening so the button presses are not missed? We are using 4 remotes that are synced to one base station so we are using the ID’s to tell a c++ software what to do off the id and then button.

Any help is greatly appreciated.

Cheers,

What code are you using?

#include "KeyFob.h"

bool checkFob = false;

void setup() {
    //Setup communication to KeyFob interface module
    pinMode(A3, INPUT);
    attachInterrupt(A3, evalFob, CHANGE);
    Serial.begin(9600);
    Serial1.begin(9600);
}

void loop() {
    //If an interrupt has fired on A3 which is connected to the fob module then a button has been pressed or released so we need to determine what button was pressed or released.
    	delay(10);

   	    
    if(checkFob){
		checkFob = false;
		fob.evalFob();
		String action;
    
        // say what you got:
        
    		switch(fob.recentAction){
    		case(fob.button1release):
    			Serial.print(fob.recentFobID);
    			Serial.print("1");
    		break;
