Multi Peripherals and One Central : BLE Configuration

I'm working on a project based on an e-paper display, I needed to send data to multiple nodes through a central node. Central Node gets the data through an online Server.

What I need help with is, how can I connect with multi UUID of peripherals as required through one Central Node. I can send the Specific data to a specific UUID by scanning all UUID around Central node.

This Communication is based on BLE.

Using Module Bluefruit nRF52832 on central node and nRF52810 on peripherals nodes.

A central device has to scan first to find the peripheral devices. A central device has to then iteratively connect to each peripheral device - it cannot connect to multiple devices simultaneously. As you are simply transferring data, I would therefore suggest doing the connect, data transfer and disconnect process for each peripheral device on your list iteratively.

Yes, I'll scan and send data to the specific node one by one which is required to update. But I can't find any code reference to set up UUID Services and Characteristics.

Where were you looking? There is plenty online, but this depends on what SDK and IDE you want to use.

For example, if you plan to use the Arduino IDE then you'll need specific libraries for the Bluefruit nRF52832 board. This is explained by Adafruit's learning guide: https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/introduction

You haven't told us what type of nRF52810 node/(ePaper) dev board you're using. If it's generic then you'll have to work out what SDK you plan to use as there is quite a few options. There is also an Arduino library, which could work too: github.com/.../arduino-nRF5
