Hi, 

i want nRF52840 to acts as central and peripheral simultaneously . how can i achieve this ?

 Please see this post.

 

i  have seen in website  nRF52840 can concurrent upto 20 link (multilink). how to do this ? which example i have to work out .

 SoftDevice S132 v4.x.x, S140 v5.x.x and later supports up to 20 concurrent connections in total. The connections can be any combination of central and peripheral.

A device can have several peripheral links.

The multilink example can be modified to support 20 connections, but currently it supports 8.

In sdk_config.h, you can modify NRF_SDH_BLE_CENTRAL_LINK_COUNT for the maximum number of central links.

thank you for your response Amanda . I have tried the central & peripheral example , i can able to connect only to one device (one peripheral ) how to connect to multiple peripheral and one central ,  i tried with the example LE secure connection multirole example, device are connecting using matched uuid , how to change uuid if i want to connect with ble uart instead of heart rate service ,how to modify the program

no no ... i want to acts as peripheral and central simultaneously , i need connect two central&peripheral combination device and 10 peripheral device , these device want to interact with each other . so how to connect the multi peripheral to central & peripheral device

The multilink example shows you how to manage multiple links.

So you take that, and use it to make your Peripheral+Central manage multiple Peripherals & Centrals.

Are you still trying to invent your own Mesh?
