A "Ble_app_multirole_lesc" program that modifies the number of "Peripheral" devices connected and changes to support "ble_nus"

Question

OS in development environment ：Windows10 HARD :(Taiyo Yuden)EBSHSN Series Evaluation Board : Central / Peripherals CPU :(Nordic) nRF52832 / ARMR Cortex-M4F 32 bit processor 28-pin Land Grid Array / 15GPIOs / SWD Soft Ver:nRF5_SDK_15.3.0_59ac345 Sample program to use: "ble_app_multirole_lesc" 
 1) Is it possible to change the number of connections by changing "NRF_SDH_BLE_PERIPHERAL_LINK_COUNT", "NRF_SDH_BLE_CENTRAL_LINK_COUNT", and "NRF_SDH_BLE_TOTAL_LINK_COUNT" of "Ble_app_multirole_lesc", and be careful? Are there any points to consider? 2) When supporting ble_nus, are "ble_app_uart_c" and "ble_app_uart" helpful? 
 Thank you

1. That is possible, just make sure you understand this affect the amount of RAM the softdevice will allocate. You should thereby check that after calling sd_ble_enable() to find the amount of RAM required by the softdevice and adjust project settings in SES or Keil accordingly. You can find example of this in nrf_sdh_ble_enable(). 
 2. Yes, and also look at the documentation: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_nus_eval.html https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_nus_c.html 
 I recommend to order an nRF52-DK for comparison when developing.
