/jtop/fan service not blocking until fan speed is reached

[ghost]

Hi,

I'm using the /jtop/fan service with the following request "{mode: manual, fanSpeed: 0}". I'm using this call in a shutdown script on a jetson nano. Even if the request is properly formed and the response is valid, when the jetson shutsdown a few seconds after the response, the fan is going back to full speed.

I'd like to have a parameter added to request a response only once the target fanSpeed is reached. I'd suggest the keyword blocking

I looked at the code and I can't seem to understand where I could get the current fanSpeed value to validate against?
