Meta Quest 3 and unity

Hi Everyone
I have a meta quest project so i need to read data from esp32 and then do something based on output
I'm using unity 6 and Meta XR AIO SDK
So could u help me so i can do it in standalone mode of Quest (not pcvr)
(If u could give me sample codes too i will be so grateful )
BTW I'm a newbie in unity 
Thanks in advance
