你好， 我用的板子是 PCA10001 ，sdk 6，s110_nrf51822_7.0.0_softdevice.hex，s120_nrf51822_1.0.0-1.alpha_softdevice.hex，代码路径：S120: \nrf6310\s120\experimental\ble_app_hrs_c s110：pca10001\s110\ble_app_hrs ，我修改了s120的led 、button、uart的管脚重定义。 我想要让主机连上从机，从机可以发送广播，但是主机不会触发任何的事件，我想要问怎么才能让主机连上从机？是不是需要特别的外部硬件？
hello my board is PCA10001 ，the sdk is 6，s110_nrf51822_7.0.0_softdevice.hex，s120_nrf51822_1.0.0-1.alpha_softdevice.hex，Code path is S120: \nrf6310\s120\experimental\ble_app_hrs_c s110：pca10001\s110\ble_app_hrs ， I modified the pin redefine led, button, uart's. I want to make a host connected to the slave, the slave can send a broadcast, but the host does not trigger any event, I want to ask how to make a host connected to the slave? Is not require special external hardware?
