Send mesh network data to clound via Raspberry pi Gateway

[Venkat RAM]

Hi Team,

I am working on NRF52832 based on the BLE mesh protocol

here I am using the Light_switch example of SDK - nrf5sdkformeshv500src 

Here I am trying on transmit a bool data from Light_switch - Client to Light_switch - Server  which ran successfully

Now my need is i want to upload all received data  in Light_switch - server  to the Cloud with raspberry pi Gateway

How to collect the data from several Light_switch - Server  in the mesh network and send it to the raspberry pi gateway

kindly guide me, Thanks in Advance

Best Regards,

Venkatraaman J S.

Hi Venkataaman, 

We don't haven an example that work out of the box to send data to the RPi. 

You need to think about how you gather data from RPi. The easiest one is to connect one of the mesh client to RPi via UART/USB. 

You can run a proprietary UART protocol between the two. 

Another option is to use our serial example on the mesh node and connect to RPi via UART and use the mesh node as connectivity device. 

You can find this implemented in the PyACI interactive example. You can find the documentation here.

Hai Hung Bui,

I am trying to install PYACI as per the blog
https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v5.0.0%2Fmd_scripts_README.html&cp=8_2_2_4_9

But the blog covers the direct information as a fresher I cant able to understand
guide me on how to install PYACI 

Kindly do needful

Hi, 

Are you familiar with Python ? 
At which step do you have an issue ? 

If you are new to embedded programming, I would suggest to find an easier solution, for example simply send the data you collect via UART and write an application on RPi to collect data in UART. 
You need to figure out how to communicate between RPi and nRF52 via UART first.

Hai Hung Bui,
" how to communicate between RPi and nRF52 via UART first" 

this only I am looking for that only I referred to the

Kindly tell me how to

I'm not very familiar with RPi development. So I can't really help you here. 
There are other threat that people have managed to make it work: 
UART Connection NRF52832 with Raspberry Pi

I would suggest you to get familiar with the UART communication between NRF52 and a PC (Windows/Linux) before you move to RPi.

Hi 
I have  well experience in python and raspberry pi

To control your device, use d[x], where x is the device index.
Devices are indexed based on the order of the COM ports specified by the -d option.
The first device, d[0], can also be accessed using device.

I am stucking here only,

as before I asked  "how to communicate between RPi and nRF52 via UART ?"
I had opened the terminal 
Here my question is  how to receive data from the nordic board
NOTE:
connection:
I had connected the nordic board with raspberry via USB
