What is Noble and How do I use it?

[jdelapena]

I have a BLE device that runs nrf51. I have an rpi3 and I want them to communicate with each other via BLE communication.

I understand that I need to develop a python application on the rpi3 side.

I have come across Noble. What is it? Will it be useful for my python application?

Thanks

Noble is a Node.js BLE (Bluetooth Low Energy) central module, so its Javascript and not python.

You will have to install the Node.js runtime on the Raspberry Pi 3, see this guide on how to install it on the Raspberry Pi 3

I have used Node.js to create a webserver using Express.js and then used Noble to receive sensor data from three BLE beacons and then display the data on a webpage.

How did you interface Noble (JavaScript) and nRF (Nordic API) ?

Hi Ananda, 
I used this example from the Noble github repo as a reference for creating the BLE central on the RPi3 side and I used this tutorial/example on the nRF Side. 

Best regards
