Cloud function getting stopped Parse.com in loop when calling from Arduino-yun

Question

I have created a cloud function using the Parse.com Javascript SDK and I am calling those functions from Arduino. Following is code for the hello function:

Parse.Cloud.define("hello", function(request, response) {
 response.success("This is hello function"); 
}); //hello function Block

I am calling this function from the Arduino side using the following code:

void setup() {
 Bridge.begin();
 Serial.begin(9600);
 while (!Serial);
 Parse.begin("***zE0uUjQkMa7nj5D5BALvzegzfyVNSG22BD***", "***Ssggp5JgMFmSHfloewW5oixlM5ibt9LBSE***");
 //commented my keys with * here only
 // In this example, we associate this device with a pre-generated installation
 Parse.getInstallationId();
 Parse.startPushService();
}
void loop() {
 Serial.println("Start loop");
 demoBasic("meeting", 0);
}
void demoBasic(String functionname, int light) {
 char fnname[11];
 functionname.toCharArray(fnname, 11);
 Serial.print("In ");
 Serial.print(functionname);
 Serial.println(" Function");
 ParseCloudFunction cloudFunction;
 cloudFunction.setFunctionName(fnname);
 cloudFunction.add("light_sensor", light);
 cloudFunction.add("value", "Arduino Hello");//parameters
 ParseResponse response = cloudFunction.send();
 Serial.println(response.getJSONBody());
}

Problem is that I am getting response 8 times only. After that whole program flow gets blocked. What is the problem?

• fabrosell: Not sure what your problem is, but I'd try a "delay" in loop after the call to demoBasic. I'd start with 100 ms. Maybe your code execute "too fast" then the js function gets blocked.
• Abhijeet Kulkarni: @fabrosell i tried doing that also but still there was problem.Can you suggest any othing thing which might solve issue.
• Abhijeet Kulkarni: If you have any working code which continuously able to push data to Parse.com,can you share that ?
• fabrosell: I'm sorry, I do not have any. Either way, it's a very strange behavior if function gets called just 8 times and no more...
• Kingsley: At what point in the code does the program flow "get blocked"?

Answer 1

Give this a shot, I really hate String, maybe that 8-times thing has to do with memory issues caused by it.

void loop() {
 char functionToCall[8] = "meeting";
 Serial.println("Start loop");
 demoBasicCharArray(functionToCall, 0);
}
void demoBasicCharArray(char *functionname, int light) {
 Serial.print("In ");
 for (byte i=0;i<sizeof(functionname);i++){
 Serial.print(functionname[i]);
 }
 Serial.println(" Function");
 ParseCloudFunction cloudFunction;
 cloudFunction.setFunctionName(functionname);
 cloudFunction.add("light_sensor", light);
 cloudFunction.add("value", "Arduino Hello");//parameters
 ParseResponse response = cloudFunction.send();
 Serial.println(response.getJSONBody());
}
