How to set up NCS so that the Bluetooth connection interval can always send data

[SOK_LiWang]

in NRF5 SDK , i can set CLE(Connection event length extension) equal to Gap event length . but in the NCS SDK , I can't find the relevant Settings . The third lesson 3  in DevAcademy's Bluetooth Low Energy Fundamentals is only about data length Settings . Whether the library can send data multiple times within a connection interval by default ?  I hope you can solve my doubts. Thank you very much .

Hello,

The event length is configured through the CONFIG_BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT symbol. Note that if you are using the nRF5340, the symbol must be applied to the BT controller running on the network core, not the main application on the appcore. You can see how the symbol is set in our 'throughput' sample here: https://github.com/nrfconnect/sdk-nrf/blob/fd87be083a2e45cb26ff09dff7380b7584095891/samples/bluetooth/throughput/child_image/hci_ipc.conf#L7C1-L7C46 

Best regards,
