i'm currently working on an object tracking drone project. I'm using a raspberry Pi as the companion computer and pixhawk as flight controller. I'm using a baud rate of 921600 since at other baud rates, i'm getting garbage values when communication is happening between pi and pixhawk. waiting for heartbeat was also shown. But this is eliminated when i use a baud rate of 921600. but when i'm running the simple goto program from dronekit, these garbage values are popping up. Can someone guide me with this?
