if you know the basic android applications development it is simple.  Jy-mcu simply connect to your UART port ie. p1.1 and p1.2.  
You first pair the jy-mcu and bluetooth in your phone .You can get android api in google
In controller side you just send data to jy-mcu as your serial terminal and receive as such
 
if you are using Energia , type this on setup.
 
Serial.begin(115200);
Serial.print("$$$");
Serial.println("U,9600,N");
Serial.begin(9600);
 
this is for default baud rate .
You can also use an additional serial ie. softwareserial to see the data on bluetooth communication
