hello friends,

basically i'm interfacing blutooth module on my uart . once blutooth module is initialised in particular profile through the controller then i want to release blutooth module rx & tx line to buffer device which received all the characters comming from blutooth module . i wanted to done it through switch like when i pass 0 to switch , switch will connect rx/tx line of blutooth module to uc uart . once initialisation process is done uc will change logic of switch so that rx/tx line of blutooth get connected to buffer device. if anyone particulalr integrated chip then please tell me because i wanted to put it on pcb so that the circuit will consume less space.
