Could you double check that your application actually do the connection parameter update request?

You can for example do so by running the application in debug mode and put a breakpoint where sd_ble_gap_conn_param_update() is called?

hi, kristin,, i use Nordic's nRF Toolbox app,,, so i think this issue is not cause by APP.

also, my application is base on "nRF5_SDK_13.0.0-1.alpha\examples\ble_peripheral\ble_app_hrs", and i see that, update_timeout_handler() call sd_ble_gap_conn_param_update() to do a connection parameter update.

In a connection, the peripheral cannot decide the connection parameters, but it can request a set of connection parameters, and the central can choose to accept or reject the update. Does your application do a connection parameter update? (sd_ble_gap_conn_param_update() )
