If you are using esp-idf v4.x or master, you can try to use this option:
CONFIG_BT_SMP_SLAVE_CON_PARAMS_UPD_ENABLE: │
│ │
│ In order to reduce the pairing time, slave actively initiates connection parameters │
│ update during pairing. │
│ │
│ Symbol: BT_SMP_SLAVE_CON_PARAMS_UPD_ENABLE [=n] │
│ Type : boolean │
│ Prompt: Slave enable connection parameters update during pairing │
│ Location: │
│ -> Component config │
│ -> Bluetooth │
│ -> Bluedroid Options │
│ -> Bluetooth Low Energy (BT_BLE_ENABLED [=y]) │
│ -> Include BLE security module(SMP) (BT_BLE_SMP_ENABLE [=y])
Also make sure you not try to send conn param update few times, because error log is suggesting you do.
