You just need to start reading through the documentation on the Espruino site. Here's one I linked for you previously which explains it: https://www.espruino.com/About+Bluetooth+LE

also , what does "data" mean? how can I understadn what he sending?

It's the 'raw' Bluetooth data that describes the other fields. You can ignore it.

is there a list of manufacturers? so number 76 is iphone (for example?)

Literally just google bluetooth le manufacturer: https://www.bluetooth.com/specifications/assigned-numbers/company-identifiers/

also what does the manufacturerData mean? how can I understand it?

It's unique to the manufacturer - so you'll have to google it and see if it is described somewhere
