Hi,Can I use my laptop to send command to pixhawk in Offboard mode? e.g. TAKEOFF LAND or local_position_setpoint.
And how to do it?
Sure, you just need a telemetry connection.
So how to achieve it? Using QGC as a host computer？ Do I need to modify the QGC source code?
Is MAVROS the only way to achieve it?Can I send MAVlink message to Pixhawk directly by my laptop?
Yes you can use mavlink directly if you like. Here's an example in C, but mavlink supports many languages. https://github.com/mavlink/c_uart_interface_example
Let me do some more research, hopefully I will find some useful information to help you set the offboard mode on your flight controller. Will get back to you as soon as I have updates HP Support Phone Number
