Unable to connect APM 2.8 to Mission Planner via bluetooth.

Issue details

Hello there, I am in the process of making my first Quadcopter but I am unable to connect my APM flight controller to mission planner using MAVlink. I am using a HC-06 bluetooth module and have set the baud rate to 57600. MP is running on Windows 7 64-bit. Selecting the correct COM port and baud rate in MP software, it tries to connect and it seems they have found each other (red led goes solid on the HC-06 and in top right corner of MP it shows connected) but then the MAVlink dialog box shows "trying to connect - timeout it 28s, 27s, 26s" and then just shows "connection failed". On clicking on details it shows "timeout" exception. Can you help me out please? I am almost about to give up on this project as it has been a month now and I cannot find any solution. I have searched extensively on the net and this site but non of them helped. I am a 9th grader and very passionate about robotics and automobiles. I would be very grateful to your help. Thank you.

No source file, test, or code entry point is identified in the report. Start by reproducing the timeout with APM 2.8, HC-06, MAVLink, Mission Planner 1.3.48, and the stated COM port and baud rate; done requires identifying whether the failure is in Mission Planner or the hardware connection and documenting a verified fix.
