How can I control blender camera in real time with android app called Sensor node Pro or Wireless IMU or Sensor Stream or SensorNode free and HyperIMU and lot of similar apps which provides python script for every app respectively.
At a very high level, you would write a modal operator that uses a timer event to communicate with your external software. You could do this by reading from a temp file that software writes to, or by using tcp sockets if your software supports that. Once you have your gimbal information you can easily apply it to the viewport camera. On the blender side of things it’s trivial, but I have no experience with your Android software so that part is a mystery to me.
Not a quick reply but i saw this post while i was researching for a solution
