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

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.

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

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,

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,
I'm not sure I understand what you are trying to do. Which blog are you talking about ?
Please try testing PYACI on a PC before you test with RPi.

I would suggest to think about the solution to make your own UART protocol between a client and RPi.

HI Hung Bui

As per the above blog

1. I used Raspberry pi 3 model B with a 16 GB SD card and newly installed os
2. python version ==> 3.9.2
then after that, I am stuck

cant able go ahead to further procedure

NOTE: I am newly installed Raspberry os, rest of python I didn't install anything

Is there any Prerequisites procedure or software required for installing in raspberry pi

Kindly help me I am new to raspberry pi regarding nrf mesh

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.

Hi team,
Sorry for inconvenience
On the subject of the ticket, they were a spelling mistake
instead of word "Cloud" mistakenly typed "Clound"
