Bluetooth Code using HC-06 module

Refer to HERE

Hi everyone,

I am trying to make an interface between an android phone and microcontroller using the HC-06 Bluetooth module.

인터페이스를 만들려한다. between 안드로이드 폰 & 마이크로컨트롤러사이에 using the HC-06을 써서.

I started this morning by trying it out on Arduino UNO

and as there are many tutorials on the internet about the same, 

I managed in perhaps the first hour to send characters from my phone.

But am a fan of PIC microcontrollers and so I decided to go for the major adventure of the day.

As it however turns out about 12 hours later, its turning into a nightmare.

I can pair with my phone and initialize the UART communication without problems.

난 페어할수있었다. with 내폰과 and 초기화할수있었다. the UART 통신을 without 문제없이.

When I start typing, I can also tell that there is signal being detected by my PIC.

when 내가 start 타이핑하기시작했을때 난 can also 말할수있었다. there is 시그널이있다고. being 감지되는 by 내 PIC에 의해.

But there seems to be no data transfer except for an error.

But 없어보인다. 데이터 송신자가 except for an 에러빼고.

What could be wrong with my code.

I'm using MikroC and MPLab with PICKIT3 and Blueterm2 in Android phone.
