    Arduino HC-05

    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?

    Which Arduino boards are you using? Are they Teensy? If not, maybe better to ask this on Arduino's forum?

    master and slave can be set via AT+ROLE=1 //1=master,0=slave

    regardless it uses AT commands and passes through data, you can use any microcontroller no library needed
