@zcmm: sd_ble_gap_conn_param_update should not be called after you call sd_ble_gap_disconnect(). But it won't harm, except for the return code 0x08 that you can ignore.

When do you start the Disconnect timer ? Note that the connection parameter update may not start immediately after you get connected but when a notification handle is enabled, depend on how you configure the start_on_notify_cccd_handle in conn_params_init().

thanks. i'm sure i can't set the interrupt priority.i find the reasons that sd_ble_gap_conn_param_updata fuc is conflict with sd_ble_gap_disconnect. After use sd_ble_gap_disconnect fuc, the link is still connected,then sd_ble_gap_conn_param_updata fuc is used and the response code is 0x00000008. at the same time,i have other questions.the APP_timer is not accuracy. In the case of the same time both #define DISCONNECT_LEVEL_MEAS_INTERVAL APP_TIMER_TICKS(5000, APP_TIMER_PRESCALER) and #define FIRST_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(5000, APP_TIMER_PRESCALER) , first of all, first open app_timer_start(m_conn_params_timer_id, timeout_ticks, NULL)（timer1） at conn_params_negotiation fuc, and then open the disconnect timer （timer 2）, but the timer 2 faster than the timer 1. why ？

@zcmm: I tried to reproduce the issue here but I haven't managed to. Attach is an example where I trigger a 1 second timer after I connect. The device got disconected and start advertising again.

Have you make sure you don't set the interrupt priority of RTC1 and SWI0 to something higher than APP_IRQ_PRIORITY_LOW ? Also please check if you have an assert when in Disconnect event. You can add a breakpoint in the app assert handler to find the error code, line number & file name of the code that cause the issue, if any.
