Unable to connect APM 2.8 to Mission Planner via bluetooth

Ground Control Software MAVLink
1

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.

Version

OS - Windows 7 64-bit; Mission Planner 1.3.48

Platform

Copter

Airframe type

Quadcopter

Hardware type

APM 2.8

**I have tried Mission Planner version 1.3.35 in which my joystick setup works(I want to fly with a joystick and joystick was not working with MP 1.3.48) fine but even there I get mavlink timeout while connecting via BT.

Here is a snapshot of the error -

Have you tried swapping your RX and TX wires? It shouldn’t hurt anything if they’re wrong. Did you configure the HC-06 with a PC before connecting it, or are you relying on the APM to configure it?

Yes, I configured the HC-06 module with my PC. I did it in the same way as explained in this post - http://ardupilot.org/copter/docs/common-mission-planner-bluetooth-connectivity.html

I think that the RX and TX wires are all right, I will try swapping them and let you know.

Thank you.

Also, it connects all right using APM Planner 2 at 57600 baud. So I don’t think that there’s any problem with HC-06’s configurations.

Im also her at this date with same problem. Bluetooth module can’t connect, even if you try everything possible. It wont connect.
Also failed to calibrate ESC. :unamused:

CAN SOMEONE FIND A SOLUTION??

The solution is to get a supported flight controller.

If you absolutely have to use APM 2.8 you need to get Mission Planner from 2015 when support for APM 2.x flight controllers was dropped.

Thank you. Will try out that
