How to identify the peripheral in Multilink central link ?

[Vipul2988]

I have connected 3 Peripheral using Name Filters and 1 central.

I am able to connect and communicate with all correctly.

But I need to identify that  conn_handle 0x0 , 0x1 and 0x2 is connected to respected which peripheral ?

I am trying on Standard example " ble_app_multilink_central "  with SDK 17.0.2. with nRF-DK 52840

Hi,

You should store this mapping yourself in the application. For instance on the BLE_GAP_EVT_CONNECTED event. You then have to use the mapping (both ways) whenever you get an event from a handle or want to send something to a given device. Remember to remove the mapping on disconnect.

Is there any standard example in SDK use same thing ?

Hi,

Yes, I found this approach in the Experimental: BLE Relay Example, which attaches to one Heart Rate Service and one Running Speed and Cadence Service. It stores in main.c the handles as m_conn_handle_hrs_c and m_conn_handle_rscs_c. That way it keeps track of which connected peripheral is which.
