Extracting data using Mavlink Router and using that data in a custom app on HereLink

Hi,

We are currently using an orange cube, and a herelink controller unit to control and move a robot. We are trying to make a custom app that will visualise important data such as voltage, current, battery, etc. However, im a bit confused on where to get started, i’ve done some research and found that the easiest most effecient way to extract the data is by using mavlink router - but how does this actually work? if i was doing this on linux i would do the following:

  1. download putty (or another similar software) and open up a new uart port
  2. set up mavlink router to route to the new uart port
  3. extract and store the data using C

can i follow the same concept on the herelink controller? is there a Putty like application that i can use on the herelink to open a Uart port? Or am i thinking to deep and there is a simpler solution?
