Arduino connected to Pixhawk(quadcopter) to capture wifi signal strengths

Using Arduino Project Guidance
1

Hello everyone,

I am currently working on a project using a quadcopter having a Pixhawk as the flight controller. Is there a way I can connect an arduino to Pixhawk, using arduino as the brain and pixhawk following the data from arduino. I also thought about using wifi pineapple. The quad is actually flying autonomously.
Any guide/input is greatly appreciated.

Hi

If I am not worng you may connect the Pin 0 (Rx) and Pin 1 (Tx) with either the UART or I2C port on your Pixhawk

Then using MAVlink you can control it
