NVIDIA Jetson AGX Outputting PWM to Flipsky VESC Issue

Hi,

I am new to working with VESC. I am developing a project where an NVIDIA Jetson Orin AGX outputs a PWM ranging from 1ms - 2ms duty cycle at 50Hz. I was able to confirm this output with an oscilloscope. When I attached it to the FLIPSKY Mini FSESC6.7 PRO 70A base on VESC6.6 in the receiver pins (meant for a radio receiver), which is connected to a Flipsky Sensored Outrunner Brushless DC Motor Battle hardened 63100 140KV, no signal was detected in the Real Time Data view of the VESC tool. I followed all of the instructions on setting up a motor and a PPM input.

I replicated it with an Arduino UNO to see if it was an issue with the 5V PWM vs 3.3V PWM and neither duty cycle showed up in the Real Time Data view.

Has anyone been able to accomplish a project similar to this where a PWM from a computer is able to control the duty cycle of the VESC?
