Multi connection via NUS

[Giang]

Hi all , I have 2 board peripheral run example ble_app_uart . I want to modify example ble_app_uart_c for concurrent connections to 2 board peripheral and send data between them . Can you show me how to modify ble_app_uart_c example for my problem . Thank ! I am using NRF52832 S132v5.0.0 SDK14.0

Hi Giang,

Please try to follow our multilink example here.

The main point is to start scanning after you get the first connection to connect to the second one.

Note that peermanager library wasn't really made to handle multiple peripherals, you may want to handle the connection event by the application.

Hi Hung Bui , I tested success the multilink example but It used lbs service and can't send string . So I want to use nus service with multilink for send string data between boards . Can you suggest me to do that ?

Do your homework, Giang. How difficult is it to change 1 byte data length to multiple bytes data length ?? Please study the code, especially on how characteristics are declared and how it's used to send and receive data. There is a tutorials section on top of this page that you can follow.

Hi Hung Bui , I have ideas is change lbs file for send multi bytes (string ) . But , a Nodric employee speak to me don't change lbs file for send multi byte that must be used nus service for this . And now I'm really confused !!

They are all proprietary services that we created as example. It's up to you to modify and change to whatever fits your need.

It's also not too hard to replace lbs with nus service. Again, up to you.
