I have APM 2.6 and I installed Mission Planner.When i want to connect this, there are a problem like no heartbeat packets received.Details are
"Can not establish a connection\n
Please check the following
- You have firmware loaded
- You have the correct serial port selected
- PX4 - You have the microsd card installed
- Try different usb port\n\n No Mavlink Heartbeat packets where read from this port
-Verify Baud Rate and setup
Mission Planner waits for 2 valid heartbeat packets before connecting
Can you help me?
