I am working on a project using arduino NANO and my output is an audio.
I want my headphone to be wireless.
Is it possible that using two bluetooth module I can send a command from bluetooth module (A) to another bluetooth module (B)?
The bluetooth module (b) is connected with a headphone and and SD card module,and when the bluetooth module B receives a command an audio file stored in SD card will be heard using a headphone.
Can I do it like that or I can connect my bluetooth module to a bluetooth headphone?
If I can connect it to a bluetooth headphone then can I use Text-to-Speech command?
