hi guys ,

i am trying to make a bluetooth based ir transmittor with the help of ir leds and bluetooth stereo audio device for following program in my phone :

https://irplus-remote.github.io/#bluetooth

the problem i face is the bluetooth module doesnt output sufficient signal from audio out port .

following is my bluetooth attached in the images

 

It's a nice picture but it obviously tells me nothing about the module characteristics.
Do you have its data sheet?

 

Get a bluetooth audio module with an amplifier that can directly drive a speaker. If that is even an audio module, as opposed to just a bluetooth receiver, then its output is not amplified to speaker level.
