I'm new here and I'm facing some problems while try to communicate with pre-designed hardware with my hc05+arduino uno.
Problems I faced is as described bellow.
1)How can i connect my hc05 automatically with pre-designed device? I've address of bluetooth used in device. Is it necessary for me to change mode of my hc05 to master?
2)How I come to know that my device is exactly connected with the device I want to connect? Any feedback signal or any function to check it?
3)I want to send command to my device via hc05(i.e. If i send command like read mobile number then device must be respond with mobile number only) How can I read command which are sent to device via hc05?
