Bluesmirf: Read/Detect if connect/disconnect state

Wireless & IoT
1

The Goal:

I am trying to get the arduino (uno) to detect if the bluesmirf (silver) is connected or not by reading the status messages sent through serial (%CONNECT or %DISCONNECT)

What I’ve done:

Using the AT Command SO I have turned on “status messages” which sends a %CONNECT or %DISCONNECT string to the local serial port everytime the bluesmirf makes a connection or loses a connection.

The Problem:

I cannot figure out how to read those two different strings (%CONNECT/%DISCONNECT)

Side Notes:

I need the arduino to read either %CONNECT or %DISCONNECT and make a decision based on either finding.

Any help at all or a point in the correct direction would amazing. Thanks.

Well since no one found anything I had to resolve this issue myself.

The answer:

In order to look for strings I had to use: find(string);

Here’s an example: ```
bluetooth.find(“%DISCONNECT”);


In that example find will look into the bluetooth for the string %DISCONNECT and if found will return true.

I have everything in a usable sketch on my website [http://www.carduino.vonini.com](http://www.carduino.vonini.com) (under arduino sketch) if anyone is interested in downloading the demo or seeing how I used it.

UPDATE:

Here is a sketch snippet from my website. It should give you a better idea of how I used find

void loop()
{
// LOCAL VARIABLES:
char c = bluetooth.find(“%CONNECT,30196692D7C0,0”); // Read bluetooth and find given string
char d = bluetooth.find(“%DISCONNECT”); // Read bluetooth and find %DISCONNECT string

if(c){ // Find %Connect String…
unlock(); // Unlock the doors
}else if(d){ // Find %Disconnect String…
lock(); // Lock the doors
}else{ // If you can’t find either string then…
if(ul){ // Check if Car is Unlocked…
if (dStatus()){ // Now check to see if bluesmirf and phone are disconnected…
lock(); // If it’s disconnected : Lock the doors
} // BUT
}else{ // If Car is Locked…
if (cStatus()){ // Check to see if bluesmirf and phone are connected…
unlock(); // If it’s connected : unlock the doors
}
}
}

if(r){ // Check to see if r(reconnect) is true…
reconnect(); // If it is TRUE then reconnect
}

}//END: loop
