I have used two arduino board's one will be having a SD card module, a HC-05 bluetooth module and an LCD display and other arduino will have a HC-05 module and will be connected to PC. I want to know how to make bidirectional communication in HC-05 bluetooth module for sending and receiving data.
And using Arduino IDE for programming. I am stuck here and need solution ASAP.
Can a HC-05 act as slave and master both if yes then how?
