Listen for Beacons
Hi;
Very frustrated with noble so testing out your libraries.
I am able to discover my devices, but how would I use this to listen for beacon transmissions and read the device manufacturer's data ?
I don't see any method or property related to the manufacturer's data.
Id not want to connect to the device, but to simply read the raw data and decode it ?
Thanks
I know, I wrote this library because I was frustrated too by noble. :) This project is quite new, It will allow you to get advertised data, but today I can't provide you an official release date. I hope to start working on it soon.
@chrvadala hey, any update on your progress? because project seems to be dead currently :(
i was looking for alternative to noble too, still no stable library for node
For anyone interested, I added the function below to node-ble/src/Device.js to receive manufacturing data (useful for reading data from Beacons):
async getManfData() { return this.helper.prop('ManufacturerData') }
which you can call like so:
const mdata = await device.getManfData()
This returns an object whose keys are the 16-bit Manufacturer ID. You may get the raw data by doing (for example):
const mdataRaw = m[Object.keys(m)[0]].value
Hope this helps!
