Thank you very much. I forgot to get the error code of sd_ble_gatts_characteristic_add(). It return NRF_ERROR_INVALID_PARAM when I set read_perm to BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM

Per spec the cccd has to be readable (BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.read_perm);). Did you check if you got an error when trying to set cccd.read_perm to BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM?

Now I can bond device with phones, thank you. I didn't remove event that on_ble_evt handled which should be handled by device manager. On more question, if I set BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM to all the read_perm/write_perm of cccd_md and attr_md, then phone will not find the device, why will this hanppen?

I would recommend that you look at one of the other examples that is using bonding, e.g. Heart rate... You are right that you need to add device manager and change the conns sec modes. In addition you should make sure you also remove events from on_ble_evt that is now handled by the device manager. And you should add sys_evt_dispatch, which is probably the part that is hardest to spot without knowing it(register with softdevice using softdevice_sys_evt_handler_set).
