Wow, that did the trick. Thank you very much RK. Regards.

so it looks like you haven't initialised the app_timer module, probably didn't need it before now, so initialise it.

i just have stepped through the ble_conn_params_init_function, the code goes all the way to:

return app_timer_create(&m_conn_params_timer_id,
                        APP_TIMER_MODE_SINGLE_SHOT,
                        update_timeout_handler);

going inside app_timer_create, and the NRF_ERROR_INVALID_STATE is returned by the very first lines of code:

// Check state and parameters
if (mp_nodes == NULL)
{
    return NRF_ERROR_INVALID_STATE;
}

Where does it fail? The APP_ERROR_CHECK() in the conn params init function or somewhere else? Have you single-stepped into the ble_conn_params_init() function to see which of the calls is returning the error? I don't see anything in the code for ble_conn_params_init() which can return that invalid state error, so perhaps it's coming from elsewhere.

And what softdevice and version?
