How to send message from two slave to one master in nRF52

[JW]

I hope to send a message from two slave to one master using nRF52 through bluetooth.

I send a message from a slave to a master with ble_app_uart_c and ble_app_uart. And I also connected two slave and one master with ble_app_multilink_central and peripheral. But I can't combine and apply that two case.

So please tell me how to send a message in multilink code, or how to use ble_app_uart as multilink.

I also found some information on internet, but I can't understand with them.

Yes,  on_ble_evt() is the same as ble_evt_handler(). 

The steps above is based on SDK 12 or 13.

From SDK 14.0.0, ble_evt_dispatch() was replaced by NRF_SDH_BLE_OBSERVER().

Thanks for your reply, but I can't get it to work, do I need to more settings ? or do I need to copy more form the uart example?
